Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of sewage-treating agent and preparation method thereof.
Background technique
With the continuous development of industry, the usage amount of water resource is consequently increased, and fresh water data increasingly lacks, and saves water money
Source and recycling water resource become focus concerned by people.In the recycling of water resource, sewage treatment is the most important thing.
Currently, the method for sewage treatment has the methods of physical method, chemical method, biological treatment, although processing method type is more, in crowd
Generally existing following problem in multiprocessing method: economic cost is high, and complex treatment process can not disposably handle harmful substance；
Often cause that treated because sewage treatment is not thorough water source still generates different degrees of harm to human body.Oil-containing in petroleum industry
Waste water mostlys come from the processes such as oil exploitation, petroleum refining and petrochemical industry production.With the development of petroleum industry, generate
Oily waste water it is more and more, its depth is buried in the soil or by the channels discharge to river of city by the selection of most of producer.
In this way, not only resulting in waste of resources, but also very big pollution is brought to environment.If oily waste water enters in soil, soil can be utilized
Earth gap forms oil film, generates clogging, causes air, moisture content and fertilizer that cannot penetrate into soil, destroys soil layer
Structure, is unfavorable for the growth of crops, will lead to crops death when serious.If oily waste water is by city channels discharge, right
Channel, auxiliary device and municipal sewage plant can all cause adverse effect.Currently, the processing for oily waste water, a part
Producer is injected into oil separator, and the oil droplet that density is less than water can rise to the water surface, and the granule foreign greater than water is sunken to bottom of pond.Needle
Insufficient to existing sewage-treating agent processing capacity, the effect for handling sewage is poor, does not fill to the processing such as particle, grease type in sewage
The problems such as dividing, the invention proposes a kind of sewage-treating agents and preparation method thereof thus.
