摘要
肉鸭养殖厂废水中污染物浓度高,简单处理后的尾水外排对当地水质构成威胁,且由于回用率低而造成水资源浪费。为改善环境污染现状,提高水资源利用率,本文根据废水特点,对原有废水处理工艺进行了改造。通过固液分离、厌氧(UASB)、好氧(接触氧化)和深度处理组合工艺方案的实施,降低了污染物的排放量,实现了90%的废水回用率,不仅减轻了当地水域的污染负荷,对于改善生态环境起到了明显的作用,具有明显的环境效益、经济效益和社会效益。
Because the high concentration of pollutants in the wastewater of duck breeding,wastewater discharged after simple treatment created a threat to local water quality,and water resources were wasted due to the low reuse rate.In order to improve the status of environmental pollution,the original wastewater treatment process was modified.Through the implementation of a combination of solid-liquid separation,anaerobic(UASB),aerobic(contact oxidation)and advanced treatment,the discharge of pollutants was reduced and 90%of wastewater was reused.The process not only reduced the pollution load of the local water,but also played a significant role in improving the ecological environment.
