化工废水是指化工厂生产产品过程中所生产的废水，如生产乙烯、聚乙烯、橡胶、聚酯、甲醇、乙二醇、油品罐区、空分空压站等装置的含油废水，经过生化处理后，一般可达到国家二级排放标准，现由于水资源的短缺，需将达到排放标准的水再经过进一步深度处理后，达到工业补水的要求并回用。

Chemical wastewater is a waste produced by the production of chemical products factory in the process of oily wastewater such as the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank, air pressure station device, after biochemical treatment, which can reach two national emission standards, due to the shortage of water resources the need to reach the discharge standard of water after further treatment, meet the industrial requirements and water reuse.

化工厂作为用水大户，年新鲜水用量一般为几百万立方米，水的重复利用率低，同时外排污水几百万立方米，不仅浪费大量水资源，也造成环境污染，并且水资源的短缺已对这些工业用水大户的生产造成威胁。为保持企业的可持续发展及减少水资源的浪费，降低生产成本，提高企业经济效益和社会效益。需对化工废水进行深度处理(三级处理)，作为循环水的补水或动力脱盐水的补水，实现污水回用。

Chemical plant as the major water users, annual amount of fresh water is generally millions of cubic meters, the water reuse rate is low, while the sewage discharged from millions of cubic meters, not only waste a lot of water resources, but also cause environmental pollution and the shortage of water resources has the large industrial water production threat. In order to maintain the sustainable development of the enterprise and reduce the waste of water resources, reduce the cost of production, improve the economic and social benefits of the enterprise. It is necessary to treat the chemical wastewater in depth (three grade treatment), which can be used as the supplement of circulating water or the supplement of power desalted water to realize the reuse of sewage.

由于水中杂质主要为悬浮颗粒和细毛纤维，利用机械过滤原理，采用微孔过滤技术将杂质去除。由PLC或时间继电器控制过滤器设备工作状况，实现自动反冲洗、自动运行，提升水泵提供过滤器所需水头，出水直接引入生产系统。

Because the impurities in the water are mainly suspended particles and fine wool fibers, the impurities are removed by microporous filtration technology by the principle of mechanical filtration. The PLC or time relay controls the working state of the filter equipment, realizes automatic backwashing and automatic operation, and improves the water head needed by the pump to provide the filter, and the effluent is directly introduced into the production system.
