Complete oily sewage treatment system

近年来石化企业多次发生污水外排及着火事件，污水处理设施的危险性并不低于生产装置。

In recent years, petrochemical enterprises have repeatedly experienced sewage discharge and fire accidents, and the risk of sewage treatment facilities is not lower than that of production devices.

石化装置生产污水及雨水均排放至废水池，此种污水组成复杂，而且事故状态下还可能排出大量的污油，这部分污油温度高、冲击量大，如果不加处理可能造成污染水体事件或火灾爆炸事故。石化含油污水组成复杂，废水主要来自费热锅炉、蒸汽发生器、碱洗塔、设备清洗时,废水种类主要是含酸、硫、碱油等。

The production sewage and rainwater of petrochemical units are discharged into the waste water tank. The composition of this kind of sewage is complex, and a large amount of waste oil may be discharged under the accident state. This part of waste oil has high temperature and large impact. If it is not treated, it may cause water pollution events or fire and explosion accidents. Petrochemical oily sewage has a complex composition. The wastewater mainly comes from waste heat boilers, steam generators, alkali washing towers and equipment cleaning. The types of wastewater are mainly acid, sulfur, alkali oil, etc.

生产车间的各股污水合并进入废水池系统后，由于原水组成复杂，在池中如果悬浮物和油的含量过高，则会形成以悬浮物和油等为载体的聚合体。聚合体长时间积累越来越大则会形成“肤皮”封死均质池，然后造成池中厌氧分解过程，产生臭气，恶化池体周围环境。

After the sewage from the production workshop is merged into the waste water tank system, due to the complex composition of raw water, if the content of suspended solids and oil in the tank is too high, it will form a polymer with suspended solids and oil as the carrier. If the polymer accumulates for a long time, it will form a “skin” to seal the homogeneous tank, and then cause the anaerobic decomposition process in the tank, generate odor, and deteriorate the surrounding environment of the tank.

根据以上实际情况开发出与废水池污水实际情况相匹配的含油污水处理成套系统。

According to the above actual situation, a complete set of oily sewage treatment system matching the actual situation of sewage in the wastewater pool is developed.

该系统可实现：出水油<50mg/l；COD<500mg/l；SS<100mg/l；

The system can achieve: outlet free oil content <50mg/l; COD<500mg/l； SS<100mg/l；
