"ah! Wake up, wake up! " Little John shook his father hard.
"Bah, I just lie down, what are you yelling about? ! "Old John lost his temper.
"I think you have been snoring for two hours. You are really tired. I hope you sit up and have a good rest.
Question 2: Has the excrement of foreigners been processed into food? This is a satire novel.
Gulliver visited the local Lagardo Academy of Sciences. Scientists there believe that "saying a word will erode the lungs more or less, thus shortening our life span." So they came up with a remedy: since words are just the names of things, isn't it more convenient to carry what you need to express your views when talking about something? This invention would have been realized long ago if women had not joined the opposition of laymen and illiterate people. "
Here, we can see at once that the author is satirizing some so-called scientists, who are thinking strange and irrelevant boring things all day. They are far less intelligent and pragmatic than ordinary people.
The author points the edge of irony at contemporary British philosophers, scientists who are divorced from reality and addicted to fantasy, absurd inventors, critics and historians who turn black and white upside down, and Britain's exposure of Irish colonial rule and oppression. Through the boring and absurd scientific research conducted by the people of the Lagardo Academy of Sciences, the pseudo-science in Britain at that time was satirized; The description of the island of Lepita criticizes the British exploitation and oppression of Ireland.
When I went to the Lagardo Academy of Sciences, I saw that unrealistic research such as extracting sunlight from cucumbers and reducing feces into food was actually aimed at the Royal Society. It can be said that it is a kind of worry first expressed in modern science and technology.
Question 3: Why do Europeans and Americans have such smelly shit ... old blacks and whites can do it. Know that you have a heavy body odor, and often use perfume for bathing. I went from high school in the United States to the second year of high school now, and those black people around me are still ok. The most unbearable thing is that people in India and the Middle East ... their underarm odor and body odor are worse than those of blacks, and they don't often take a shower and change clothes. This woman from the Middle East sat in front of my economics class, with a black headscarf on her head, and always smelled that terrible smell in class. I remember one exam, I almost fainted by her. ......
Question 4: Why do some people think that foreigners' excrement is fragrant and China stinks? I said: do you feel particularly comfortable because you were eaten ~!
The basic meaning is dissatisfaction with today's society ~ Don't be so ugly, everyone has their own right to reasonable demands ~
Question 5: 300: What do foreigners use to wipe their hands after defecation?
Question 6: Why do westerners and Americans like to eat shit and eat it with relish for 20 minutes? This question is easy to answer, just like a fish knows the happiness of a fish. If you are not a dog, how do you know why dogs eat shit? So this question is not worth going into, unless. . . You want to be. . . Forget it, okay?
Question 7: How do foreigners shit? Poop? Yes, children usually say poopoopoo, and when they are dirty, they say shit, where shit is a verb.
Question 8: How to deal with human excrement According to the co-construction mode of urban excrement treatment plant and urban sewage treatment plant, the excrement treatment plant, as the pretreatment workshop of excrement treatment, adopts physical pretreatment, that is, mechanical equipment is used to separate the residue and moisture in excrement. After harmless treatment, the separated residue can be directly buried or used as fertilizer for landscaping, and the separated sewage can be directly discharged into the urban sewage treatment plant as its nutrient water.
In order to choose a good process and achieve an ideal treatment effect, the following three schemes are tentatively compared.
Scheme I evaluation:
Main advantages:
The main purpose of this scheme is to separate large solid particles from fecal liquid, avoid blocking the pipeline when discharged into sewage pipe network and increase the solid load of sewage plant.
Main defects:
1. Because fecal liquid is mainly extracted from chemical septic tanks, the sand content in fecal liquid is very high. If only a grid is separated, a large number of sand grains in the dung liquid will be discharged into the urban sewage pipe network with the pipeline, and the volume will be deposited in the pipe network, which will directly affect the smooth drainage pipe and sewage discharge, resulting in serious consequences.
2. Due to the extremely high organic matter content in fecal liquid, the COD content is about 20,000 mg/L, which is about 100 times that of municipal sewage. If this kind of high-concentration sewage is directly discharged into the urban sewage pipe network, it will be fatal to urban sewage treatment. Because the sewage concentration designed by the sewage plant is the concentration of urban sewage, the treatment structures and equipment of the sewage plant are also designed according to this concentration. If fecal sewage is added, the load of each treatment link of the sewage plant will increase a lot, and the same biochemical treatment capacity will meet the design requirements, and the effluent will not meet the standard.
Option 2 Assessment:
Main advantages:
1. Due to the coarse grille, larger solid particles in the feces will be separated to avoid blocking the pipeline when discharged into the sewage pipe network and increase the solid load of the sewage plant.
2. An integrated separation device is added, including a fine grid and a grit chamber. Its main function is to further effectively separate the small solid particles in the fecal liquid intercepted by the coarse grid, and at the same time, separate the sand particles that are easy to deposit in the fecal liquid through the grit chamber to avoid the sand accumulation problem in the sewage pipe network.
Main defects:
Because the coarse grid and the integrated separator only remove the inorganic substances in the fecal liquid, the ability to remove the organic substances in the fecal liquid is very small. Similarly, the COD concentration of the sewage discharged through the integrated separator is still very high, which has a great impact on the urban sewage treatment plant and seriously affects the normal operation of the sewage plant.
Option 3 Assessment:
Main advantages:
1. Due to the coarse grid and integrated separation device, the solid suspended solids and sand grains in the fecal liquid will be effectively removed, and there will be no problem of sewage pipe network blockage and the influence of solid load on the sewage plant.
2. Due to the addition of a sludge dewatering machine, the sludge dewatering is to add a polymer flocculant to the fecal liquid, so that most of the flocculatable organic matter and suspended inorganic matter in the fecal liquid form flocs, and then the filtered liquid is squeezed by the sludge dewatering machine, so that the COD concentration in the fecal liquid can be greatly reduced, and the COD concentration in the filtered liquid is below 2000 mg/L. Thus, the filtered liquid is discharged into the sewage pipe network, and the diluted concentration of the sewage has little influence on the sewage, which is harmful to the urban sewage plant.
3. The sludge dehydrated by the sludge dehydrator can be recycled, which is a high-quality fertilizer raw material with higher utilization value than chemical fertilizer and organic fertilizer, and can be used for farmland or tree planting.
To sum up, in order to ensure the harmless discharge of feces and reduce the impact on sewage treatment plants, Scheme III is better.
3. Process introduction
Firstly, the excrement is discharged into a ditch with a coarse grid, and the larger solid particles in the excrement are intercepted by the coarse grid, and then enter an integrated separation device, and the small particles in the excrement liquid are intercepted by the fine grid, and then the sand particles in the excrement liquid are precipitated and lifted by a grit chamber. The sewage discharged from the integrated separation device enters a large-volume dung storage tank, and a stirrer is installed in the dung storage tank to evenly mix the dung liquid, and then the dung liquid is pumped into the sludge dehydrator by a lift pump. Polymer flocculant is added in the lifting process, so that the organic matter and suspended matter in the sewage form flocs and enter the dehydrator for dehydration. Finally, the dehydrated sludge is transported away for utilization, and the filtered liquid is discharged into the sewage pipe network. ...& gt& gt
Question 9: Do foreigners grow vegetables and dump manure? It should be said that people all over the world grow vegetables with manure. The difference is that some are treated and some are directly watered.
Question 10: Where did ancient westerners urinate? There were no toilets in early residential buildings, and people used toilets. The use of toilets is only a few cases in the history of western civilization. Although the Roman Empire had an advanced sewage and drainage network as early as the 4th century BC, it was not until the 9th century AD/KLOC-0 that the modern sewage and drainage system was gradually developed in Britain. The excavation of Herculaneum shows that all the houses, even the apartments on the second floor, are equipped with toilets. According to the records in the later period of the empire, there were 144 public toilets in Rome, all of which were built next to public bathhouses, so it was convenient to wash them with dirty water from bathhouses. blog.sina/s/blog_485a49d90 10008se
