摘要
肉鸭养殖宰杀产业废水排放量大,污染物浓度高,简单处理后的水外排对水质有较大影响。在此以某肉鸭养殖宰杀企业为例,对原有污水处理工艺进行改造,通过增加深度处理单元以及对废水进行回用,降低了污染物的浓度,实现了80%的废水回用率。工程的实施给企业带来巨大的经济效益,减轻了当地水域的污染负荷,对于改善其生态环境起到了巨大的作用,具有明显的环境、经济和社会效益。
Duck cultivation and slaughter industry produces a large quantity of wastewater with high concentration pollutants. The external effluent discharge by simple treatment has great impact on Huaihe river. Therefore, taking some duck cultivation and slaughter enterprise as an example, through transforming the original sewage treatment craft, increasing the advanced treatment unit and reusing wastewater, the enterprise reduced the pollutant concentration and realized to recycle 80 percent of wastewater. This project can bring the huge benefit to the enterprise, while alleviate the local water pollution load and improve the local ecological environment, with obvious environmental, economic and social efficiency.
