Lysine production wastewater reuse to remove ammonia nitrogen denitrification factors in a few days ago in a wastewater treatment technology on the BBS see wastewater treatment to remove ammonia nitrogen denitrification technology, but also influence the wastewater treatment of removing ammonia nitrogen factors affecting denitrification also list, just a little bit up, for your reference. The main factors affecting denitrification: ( 1) , temperature, the influence of temperature on the denitrification than other wastewater biological treatment processes be larger, generally, in order to maintain 20 ~ 40 ℃ advisable. Bitter at low temperature in winter, can be taken to increase the sludge retention time and reduce the load, in order to keep good denitrification effect. ( 2) , pH value, the pH of the denitrification process control at 7. 0 to 8. 0. ( 3) , dissolved oxygen, oxygen has inhibitory effect on denitrifying denitrification, in dissolved oxygen in the denitrifying reactor should be controlled in 0. Below 5 mg/L ( Activated sludge process) Or below 1 mg/L ( Biological membrane method) 。 ( 4) , organic carbon source: when the wastewater contains enough organic carbon source, BOD5 / TN> ( 3 ~ 5) When no additional carbon source. When the wastewater contains carbon and nitrogen ratio is lower than the ratio, we have to another additive organic carbon. Plus more organic carbon by methanol. Considering the additional methanol of dissolved oxygen consumption, methanol dosage for NO3 - in general - - - - - - N three times, in addition, still can use microbial death, autolyzed released after that part of the organic carbon, namely & quot; The carbon source & quot; , but this requires that the sludge retention time long or low load rate, make the growth curve of the stationary phase in the microbial or decline phase, therefore ChiRong increases accordingly. For wastewater treatment to remove ammonia nitrogen denitrification effect is simple and to the point, if you have a good method of removing ammonia nitrogen wastewater treatment can be below comments and discussion, let's learn together.
