Abstract

The invention provides a chemical sewage treatment method. Operation is completed through cooperation of an outer frame, a grinding device, a stirring device, a sediment collecting device and a sealing device. According to the invention, the problems that during precipitation treatment, a solid precipitant is put into sewage for precipitation treatment, however, due to the fact that the sewage conveying flow speed is high, particles of the solid precipitant are large, the solid precipitant is difficult to dissolve quickly when placed in sewage, precipitates stand in a precipitation tank afterprecipitation, and when the sewage flows and is discharged again, the standing precipitates can be turned over again under the flowing condition of the sewage, and collection of the precipitates is not facilitated are solved.

Description

technical field [0001] The invention relates to the technical field of chemical sewage treatment, in particular to a chemical sewage treatment method. Background technique [0002] Chemical sewage refers to pure water that has changed its original physical or chemical properties after use and has become wastewater containing different types of impurities. Chemical sewage is process wastewater, cooling water, exhaust gas washing water, Equipment and site flushing water and other wastewater, if discharged without treatment, will cause different properties and degrees of pollution of the water body, thereby endangering human health and affecting industrial and agricultural production. [0003] People usually carry out sedimentation treatment on chemical sewage. During the treatment, solid precipitants are usually put into the sewage for precipitation treatment. However, some problems are often encountered during the precipitation process. Due to the fast flow rate of sewage tra...
