摘要
某机械加工企业园区建设不同途径水环境综合治理工程,采用生物流化床、人工湿地等技术对企业生产废水和生活污水进行处理和生态净化,对收集到的雨水进行过滤净化。生产废水、生活污水和雨水经处理后达到GB/T 18921—2002《城市污水再生利用景观环境用水水质》要求后,回用于景观湖给水。该工程的建设减少了企业污染物的排放,节约水资源,实现了水资源的再利用。
A project of comprehensive treatment of water environment was constructed in a mechanical processing enterprise park. The industrial wastewater and domestic sewage was treated and purified by biological fluidized bed, artificial wetland and some other process, meanwhile, the collected rainwater was also filtrated and purified. Through the treatment, the quality of the industrial wastewater, the domestic sewage and the rainwater met the requirement of GB/T 18921 -2002 The Reuse of Urban Recycling Water -Water Quality Standard for Scenic Environment Use, which could be reused as the make-up water of landscape lake. Benefit from the said project, pollutants discharge from the enterprise was reduced, water resource was saved, and water resource reutilization was realized.
