【摘要】：近年来随着环保技术的日益完善和环保形势的日益严峻,与铜冶炼企业相关的行业规范条件、清洁生产标准以及其它环境保护政策不断出台,为节约水资源和保护水环境,金隆公司实施水环境综合治理工程。金隆公司是国内首座自行设计的大型闪速铜冶炼厂,工艺流程较长且工艺过程复杂,通过分析铜冶炼企业废水的来源与性质,深入细致调研金隆公司水环境现状,结合国内铜冶炼企业实际,针对金隆公司目前存在总给排水量较大,工业用水重复利用率偏低,且排水管网为合流制,平时及下雨时SS、COD及重金属元素未稳定达标,生产污水处理站处理能力不够,未设置事故水池等问题,确定技改方案。主要技术措施如下:(1)从源头节水减污,清污分流,控制污染,一水多用,生产废水分质收集、处理和重复利用,提高工业用水重复利用率,最大限度减少废水产生量,降低末端治理成本。完善设备循环冷却水设施,增设生活污水管及收集池、增设生产废水管及收集池,分区域治理和收集目前厂区界内未收集的受污染场地及道路冲洗水、道路初期雨水,改造雨水排水系统,减少工厂对外排水口,每个排水口前均设置事故及初期雨水收集池,以防止污染外部水体。(2)增设或改扩建各类废水处理及回用设施。改扩建酸性污水处理站,提高污水处理能力;增设废水深度处理站,达标废水全部回用于生产;增设初期雨水处理站,初期雨水处理达标后外排或回用;增设生活污水处理设施,生活污水处理达标后回用于绿化或浇洒道路。工程实施后,能较好地解决含重金属离子污水对环境的污染,满足现行国家环保要求,实现企业社会效益和环境效益,还可为其它同类铜冶炼企业提供良好的参考与示范。
[Abstract]:In recent years, with the improvement of environmental protection technology and the increasingly severe environmental protection situation, the industry standard conditions, cleaner production standards and other environmental protection policies related to copper smelting enterprises have been issued continuously, in order to save water resources and protect the water environment, Jinlong company implements water environment comprehensive treatment project. Jinlong Company is the first large flash copper smelter designed by itself in China. The process is long and complex. By analyzing the sources and properties of wastewater from copper smelting enterprises, the present situation of water environment in Jinlong Company is investigated deeply and meticulously. In view of the actual situation of domestic copper smelting enterprises, there is a large amount of total water supply and drainage in Jinlong Company, the reuse rate of industrial water is on the low side, and the drainage pipe network is a combined flow system. The SS,COD and heavy metal elements are not stable up to the standard at ordinary times and when it rains. The treatment capacity of the sewage treatment station is not enough and the accident pool is not set up. The main technical measures are as follows: (1) Water saving and pollution reduction, decontamination and diversion, pollution control, multi-use of water, collection, treatment and reuse of production wastewater, increasing the reuse rate of industrial water, and minimizing the amount of wastewater production, Reduce terminal management costs. Improve equipment circulating cooling water facilities, add domestic sewage pipes and collection ponds, increase production wastewater pipes and collection ponds, treat and collect contaminated sites and roads not collected at present in the factory area, and wash water from roads, Rain Water at the beginning of the road, In order to prevent the pollution of external water body, Rain Water drainage system is reformed and the external drainage outlet of the factory is reduced. In order to prevent the pollution of the external water body, an accident and an initial Rain Water collection pool are set up in front of each drain outlet. (2) various kinds of wastewater treatment and reuse facilities are added or renovated. To rebuild and expand the acid sewage treatment station to improve the sewage treatment capacity, to increase the advanced treatment station of wastewater, to reuse all the wastewater up to the standard in production, to add the initial Rain Water treatment station, and to discharge or reuse the wastewater after the initial UNOMI_person1# treatment reached the standard; Additional domestic sewage treatment facilities, domestic sewage treatment standards for reuse in greening or sprinkling roads. After the implementation of the project, the pollution caused by the sewage containing heavy metal ions to the environment can be well solved, the current national environmental protection requirements can be satisfied, and the social and environmental benefits of the enterprise can be realized. It can also provide a good reference and demonstration for other similar copper smelting enterprises.
