Question 3: What about high ammonia nitrogen in sewage treatment? Reduce the amount of water intake, reduce the internal reflux ratio, extend the actual hydraulic retention time of the aerobic unit, improve the nitrification effect pay close attention to other water quality indicators and sludge indicators of change;
Try to avoid the phenomenon of sludge disintegration or sludge expansion; if the case should be quickly to the system to add rogue coagulant or iron salts, to improve the performance of the sludge flocculation and settling;
Concerned about the pH and TP situation, try to ensure that the system is in a weakly alkaline environment, to ensure that the system is in a weakly alkaline environment.
If the TP concentration in the reactor is significantly lower than the usual level, the system should be supplemented with appropriate dihydrogen phosphate bait or phosphate fertilizer to improve the flocculation effect of the sludge and the nitrification ability;
Increase the external reflux ratio, maintain the relatively high sludge concentration in the biochemical unit, and improve the system's resistance to flocculation and nitrification.
Increase the ratio of external return flow, maintain a relatively high sludge concentration in the biochemical unit to improve the shock load resistance of the system;
Increase the DO concentration (2.5 -4.0 mglL) to improve the nitrification effect;
After this part of sludge enters the secondary sedimentation tank, reduce the external return flow and increase the discharge of residual sludge, so that this part of the sludge can be treated as soon as possible without any harmful effects;
If the condition permits, you can determine the respiration index and nitrification rate of the sludge respectively.
If conditions permit, the sludge respiration index and nitrification rate can be measured separately to assist in the judgment of the cause of exceeding the standard;
Increase the sampling frequency of laboratory analysis to test the effect of emergency measures taken to improve the quality of the effluent, or else other methods should be replaced or a variety of methods should be used in conjunction with each other to shorten the recovery time of the treatment system as much as possible.

Question 4: municipal wastewater treatment plant influent ammonia nitrogen is too high out of the water is constantly rising how? Only the nitrification process can be converted to nitrate or nitrite nitrogen, not to rise, may be only treated to the carbonation stage of sewage, not convulsive into the nitrification stage, in the process of some organic nitrogen into ammonia nitrogen it!
Not into the nitrification stage should be more general, organic nitrogen in the nitrification stage before the ammonification stage of organic nitrogen into ammoniacal nitrogen, which caused the measurement before and after the later does not fall but rise.
1. Through the aeration of the biofilter after the wastewater in the organic nitrogen is ammoniated to ammonia nitrogen, so the monitoring of ammonia nitrogen will be found to be elevated;
2. Aeration of the pool of filter media and aeration method of choice has a problem, the pool of sludge is basically a reproduction of the water discharged with the water, there is no guarantee of the age of the natural nitrification of the bacteria can not be formed, that is to say, the NH4-N elevated, but was not removed;
3. p>
3. Aerated biofilter gas can not be large and must be uniform, for the influent COD higher wastewater is not suitable, of course, the exception of the contact oxidation process;
Problem 5: how to do the wastewater ammonia nitrogen exceeds the standard? Wastewater ammonia nitrogen removal of the most traditional process is blowing off the method, but this process has a large footprint, high operating costs, noise and other shortcomings. At present, the most effective method for ammonia wastewater treatment should be the deamination membrane method, this equipment technology NH3 separation and absorption is completed at the same time on the inside and outside of the membrane filament, eliminating the action of the traditional process of blowing air, saving a lot of power consumption, but also enhance the ammonia nitrogen removal rate.
Question 6: What causes high ammonia nitrogen Ammonia nitrogen (NH3-N) mainly comes from bait (feed), aquatic animal excreta, fertilizers and animal carcasses decomposition. Ammonia nitrogen is the main waste nitrogen in the water body, in the pool water pH is high, ammonia nitrogen can return to the atmosphere, or in the form of nitrogen back to the atmosphere, but also partially consumed by aquatic plants, partially adsorbed by the substrate. Ammonia nitrogen is usually produced as a result of the decomposition of nitrogenous organic matter in times of insufficient oxygen, or as a result of the reduction of nitrogen compounds by denitrifying bacteria.
Question 7: Please ask the CEO's of wastewater treatment. Please ask the CEO's of sewage treatment. Please ask the CEO of domestic wastewater treatment ammonia nitrogen is high, what to be Ammonia nitrogen is nitrogen that exists in water in the form of free ammonia (NH3) and ammonium ions (NH4+). Biological method is to use the synergistic effect of various microorganisms, through the ammonia, nitrification, denitrification and a series of reactions to make the ammonia nitrogen in the wastewater is ultimately converted into nitrogen gas emissions so as to remove the ammonia nitrogen method, mainly including the traditional nitrification denitrification, short-range nitrification denitrification, synchronous nitrification denitrification and anaerobic ammonia oxidation and other processes. The high concentration of ammonia nitrogen has an inhibitory effect on the nitrification process, so the biological method is often used to treat domestic wastewater containing more organic matter but relatively low ammonia nitrogen concentration. Ammonia nitrogen in domestic wastewater treatment is removed through the nitrification process, high ammonia nitrogen in wastewater treatment effluent is caused by the nitrification process is not complete.
Corresponding treatment:
1, to solve the problem of insufficient charcoal source
2, to control the aerobic stage DO for 0.5 mg/L
Attachment: charcoal consumption and supplementation of the principle of work
Nitrification reaction process: under aerobic conditions, ammonia nitrogen is oxidized by the nitrifying bacteria to become nitrite and nitrate. He includes two basic reaction steps: the nitrite bacteria (Nitrosomonas sp) involved in the conversion of ammonia nitrogen into nitrite reaction; nitrate bacteria (Nitrobactersp) involved in the conversion of nitrite into nitrate reaction, nitrite bacteria and nitrate bacteria are chemo-energetic autotrophic bacteria, which use CO2, CO32-, HCO3- and so on as a carbon source, by the NH3, NH4+, or NO2- redox reaction to obtain energy. The nitrification process needs to be carried out under aerobic (Aerobic or Oxic) conditions, with oxygen as the electron acceptor and nitrogen as the electron donor. The corresponding reaction equation is: nitrosation reaction equation: 55NH4 + + 76O2 + 109HCO3 → C5H7O2N + 54NO2 - + 57H2O + 104H2CO3 nitrification reaction equation: 400NO2 - + 195O2 + NH4 - + 4H2CO3 + HCO3 - → C5H7O2N + 400NO3 - + 3H2O nitrification Process total reaction equation: NH4-+1.83O2+1.98HCO3→0.021C5H7O2N+0.98NO3-+1.04H2O+1.884H2CO3 Through the material accounting of the above reaction process, it can be seen that, in the process of nitrification reaction, oxidizing 1 gram of ammonia nitrogen to nitrate nitrogen requires 4.57 grams of oxygen (of which nitrosation requires 3.43 grams of oxygen consumption. Nitrification reaction consumes 1.14 grams of oxygen), while about 7.14 grams of bicarbonate (as CaCO3) alkalinity need to be consumed. During the nitrification reaction, the conversion of nitrogen undergoes the following processes:
Ammonia ion NH4-→hydroxylamine NH2OH→nitroyl NOH→nitrite NO2-→nitrate NO3-.
