Problems solved by technology

[0003] At present, although the sewage treatment system has been widely used in concrete mixing plants, it can complete the separation of sand, stone and sewage, but it has not realized the treatment of sewage. The sewage contains more fine sand and mortar, and the cleanliness is not high.

Abstract

The invention relates to a sewage treatment zero discharge system which comprises a sand and stone separation system used for sand and stone separation, a fine sand recovery system used for fine sandrecovery, a sewage stirring system used for preventing sewage precipitation and solidification, a sewage concentration regulating system used for regulating the sewage concentration and a sewage recycling system used for sewage recycling. The fine sand recovery system, the sewage stirring system, the sewage concentration regulating system and the sewage recycling system are sequentially connectedthrough a sewage pipeline. The sewage treatment zero discharge system provided by the invention has the benefits that sand and stones in waste materials are separated and then are recycled, the sewageis recycled through concentration regulation, the zero sewage discharge of an environmentally-friendly stirring station is achieved, the problems of excessive discharge of the various waste materialsand muddy water at the stirring station site and environmental pollution are effectively solved, and meanwhile, the problem that the waste materials cannot be effectively utilized is solved.

Description

technical field [0001] The present invention relates to the technical field of sewage treatment, and concrete sewage treatment equipment, in particular, to a sewage treatment zero discharge system, which is mainly used to separate and recycle stones, sand and mortar water in the process of sewage recovery, It can achieve zero discharge of fine sand and sewage. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete is widely used in the field of civil engineering construction. In the concrete mixing plant, the main sources of sewage generated are as follows: 1. A part of the concrete remaining in the tank truc...
