Micro-power sewage treatment process--Integrated buried domestic sewage treatment equipment (each part of the introduction)?
(1) Class A biochemical tank?
In order to control the dissolved oxygen in the class A biochemical tank at about 0.5mg/l, the tank adopts interstitial aeration. the packing of the class A biochemical tank adopts the new type of elastic three-dimensional packing, which has the advantages of not easy to be blocked, light weight, large specific surface area, stable treatment effect, etc., and it is easy to be overhauled and replaced.
(2) O-level biochemical tank?
The packing of A/O biochemical tank adopts columnar bio-carrier packing, which has a large specific surface area and is 16-20 times of the general bio-filling (same unit volume), so the tank maintains a high biomass to achieve the purpose of high-speed removal of organic pollutants. The aeration equipment adopts blower and microporous aerator, the utilization rate of oxygen is more than 30%, which effectively saves the operation cost.
(3) two sedimentation tank?
After the sewage is treated by the O-level biochemical tank, the water contains a large number of suspended solids (biofilm detachment), in order to make the effluent SS meet the discharge standard, the vertical flow sedimentation tank is used to carry out solid-liquid separation. There is one sedimentation tank, with a surface load of 1.0m3/m2-hr. The sludge of the sedimentation tank is lifted to the sludge tank by pneumatic lifting equipment, and at the same time, the sludge can be partially lifted to the A-stage biochemical tank for sludge reflux according to the actual water quality to increase the concentration of the sludge in the O-stage biochemical tank and to improve the removal efficiency.
(4) Sludge tank?
Sedimentation tank sludge is lifted by air to the sludge tank for nitrification at room temperature, and the supernatant of the sludge tank is refluxed to the contact oxidation tank for reprocessing, and the remaining sludge after nitrification is very little, and it can be cleaned up generally more than half a year. The cleaning method can be used suction manure truck from the sludge pool inspection hole into the bottom of the sludge for suction transportation can be.
Micro power sewage treatment process--? Scope of application
Integrated sewage treatment equipment is suitable for residential areas, villages, villages and towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, institutions, schools, troops, hospitals, highways, railroads, factories, mines, tourist attractions and other domestic sewage and similar slaughtering, aquatic products, food and other small and medium-sized scale industrial organic wastewater treatment and reuse. The sewage treated by the equipment, the water quality to meet the national sewage treatment standards for the comprehensive discharge of primary B standards.
Micro-power wastewater treatment process - integrated wastewater treatment equipment, has the following characteristics:
(1) High efficiency.
The process has high removal effect on organic matter, ammonia and nitrogen in wastewater. When the total retention time is more than 54h, the effluent after biological denitrification and then after coagulation and precipitation, the COD value can be reduced to less than 100mg/L, and other indicators also meet the discharge standards, the total nitrogen removal rate of more than 70%.
(2) Simple process, investment, low operating costs.
The process is to use the organic matter in wastewater as the carbon source for denitrification, so there is no need to add another expensive carbon source such as methanol. Especially, after the ammonia evaporation tower is set up with the device of removing fixed ammonia, the carbon and nitrogen ratio is improved, and the alkalinity produced in the denitrification process correspondingly reduces the alkali consumption required for the nitrification process.
(3) high volumetric load.
Since the nitrification stage adopts enhanced biochemical, denitrification stage and the use of high concentration of sludge membrane technology, effectively improve the nitrification and denitrification of sludge concentration, compared with similar processes abroad, has a high volumetric load.
(4) The anoxic/aerobic process has a strong load impact resistance.
When the influent water quality fluctuates greatly or the concentration of pollutants is high, this process can maintain normal operation, so the operation and management is also very simple. Through the comparison of the above processes, it is easy to see that the biological denitrification process itself is to remove nitrogen at the same time, but also degradation of phenol, cyanide, COD and other organic matter. Combined with the amount of water, water quality characteristics, we recommend the use of anoxic / aerobic (A/O) biological denitrification (internal circulation) process, so that the wastewater treatment plant can not only meet the requirements of nitrogen removal, but also other indicators to meet the emission standards.
Micro-power sewage treatment process - the role of anaerobic biofilter principle
1), filtration: filler retention of large particles and suspended solids filtered into the water;
2), hydrolysis: anaerobic microorganisms can be hydrolyzed large molecules of insoluble substances into small molecules of soluble substances;
2), hydrolysis: anaerobic microorganisms can hydrolyze large molecules of insoluble substances into small molecules of soluble substances. soluble substances;
3), absorption: anaerobic microorganisms adsorb and absorb organic pollutants in water, part of which is used for their own growth and reproduction, and part of which is in the form of biogas through the U-type water seal;
4), denitrification: the effluent from the contact oxidation bed is refluxed into the anaerobic filtration tank, and the denitrifying bacteria in the anaerobic microorganisms can utilize the nitrate nitrogen in the refluxed water and convert it into nitrogen, so as to remove the nitrogen in the wastewater. to nitrogen to remove the nitrogen in the sewage.
