Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a sewage treatment device used in a concrete mixing station. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added in a certain proportion, which are uniformly mixed, compacted, cured and hardened. As a concrete prefabrication site, a concrete mixing station will produce sewage in the process of mixing and preparing concrete. The main sources of this sewage are sewage generated by the washing of transportation vehicles, sewage generated by site cleaning, and sewage generated by the cleaning of supporting facilities of the mixing building during the production process. These sewages not only contain cement, soil, sand and other materials, but also contain oil, concrete additives and other ingredients. If discharged at will, it will pollute water sources and soil. Therefore, it is necessary to treat the sewage step by step. Therefore, a sewage treatment device for a concrete mixing station is needed.

This not only easily causes a large amount of fine sand and mud to accumulate and precipitate in the pool, but also requires regular manual cleaning of the pool, which is labor-consuming and time-consuming. In response to this technical problem, this application proposes a sewage treatment device for a concrete mixing station. Utility Model Content
