Question

摘要 宏昌制革厂的废水生化处理性较好，现有的工艺能使CODcr保持300 mg/L左右但氨氮不达标。标该公司通过投加德国的硝化菌种、系统调试以及优化现有污水处理工艺等措施来降低氨氮指标，前期一段时间最低氨氮降至10mg/L以下，目前由于气温有所下降，但也在70至90mg/L左右波动，去除率在40%至50%左右，相信再经过一段时间可以达到更低的范围。并积极开发韩国新的工艺来降低废水中氨氮含量。

Answer 1

Summary: Hong Chang tanyard is good at the biochemical treatment of wastewater ,the existing process can make CODcr maintain about 300 mg/L but ammonia nitrogen be discontinued. The company has put added the Germany denitrification stains, System debug and optimize the existing sewage disposal process and other measures to reduce the ammonia nitrogen indicators, the earlier stage of ammonia nitrogen dropped to below the minimum 10mg/L.At present for the temperature has dropped, but in volatile about 70-90mg/L , the removal rate of 40% to 50%, it could be even lower scope after a period of time . and actively develop the South korea's new technologies to reduce wastewater content of the ammonia nitrogen.

Answer 2

The wastewater biochemical place HongChang manufacture leather rational better, the existing technology can make CODcr keep 300 mg/L or so but ammonia nitrogen substandard. Marking the company through the dosing German nitration strains, system and adjustment and optimization existing measures such as sewage treatment process to reduce the ammonia nitrogen index, the prophase period of time reduced to the minimum ammonia nitrogen 10mg/L below, at present due to temperature has dropped, but also in the 70 to 90mg/L or so fluctuations in 40% to 50%, removal rate around again, believe that over a period of time, can achieve lower range. And actively develops the Korean new technology to reduce the waste of ammonia nitrogen content.
