英语翻译摘要 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

Abstract:Venture tannery wastewater treatment is better,to maintain the existing technology can CODcr 300 mg / L,but ammonia is not about standards.The pany marked the addition of nitrification bacteria in Germany,system debugging and optimization of existing sewage treatment process indicators and other measures to reduce ammonia,ammonia down to a minimum period of time pre-10mg / L below the present,because the temperature has dropped,but also 70 to 90mg / L is about fluctuations in the removal rate 40% to 50%,then after a period of time that can reach the lower range.And actively develop new technology to reduce South Korea in the ammonia content of wastewater.
