Construction method of rain and sewage purification treatment system in ready-mixed concrete production plant area

Abstract

The invention relates to a construction method of a rain and sewage purification treatment system in a ready-mixed concrete production plant area. The method includes the following steps: (1) designing a drainage ditch, a sedimentation tank, a water collecting tank and a car washing room; (2) preforming drainage ditch construction; (3) preforming sedimentation tank construction; (4) preforming water collecting tank construction; (5) arranging the car washing room. The method has the advantages that a ditch top cover plate of the drainage ditch is connected with a cover plate cross beam, so that the bearing capacity of the ditch top cover plate can be effectively improved; through the arrangement of a shock absorption layer at the bottom of the beam, the anti-seismic performance of the structure can be improved; an elastic connector is arranged between a sliding groove channel and a sliding pull rod, so that the quality of dirt removal in the drainage ditch can be effectively improved;the sliding groove channel is formed in the bottom of the sedimentation tank, and the sliding groove channel is connected with a sliding limiting plate, so that the efficiency of removing dirt insidethe sedimentation tank can be effectively improved; and the water collecting tank is communicated with a dirt collecting tank, so that the layered filtering effect is good, dirt is respectively liftedand taken out in the dirt collecting tank through a lifting ring, and the on-site construction efficiency is high.

Description

technical field [0001] The invention relates to a construction method of a rainwater purification treatment system in a ready-mixed concrete production plant area, belongs to the field of architecture and civil engineering, and is suitable for a rainwater sewage purification treatment project in a ready-mixed concrete production plant area. Background technique [0002] When producing and transporting various types of concrete products in commercial mixing plants, a large amount of sewage will inevitably be produced. The main sources of sewage are cleaning concrete transport vehicles, transport pump trucks, sewage from the mixing plant itself, and precipitation in the production plant area. These rain Sewage contains a large amount of insoluble matter such as cement and sand, which must be treated before discharge. [0003] In the prior art, the existing mixing station adopts the one-time full recycling method of sewage with low treatment cost, that is, the sewage is not sep...

Problems solved by technology

The advantages of adopting such a full-cycle sewage recovery method are: greatly reduced pollution, basically zero discharge, zero cleaning, zero external transportation, and most of the resources can be recovered, but there are still disadvantages such as high energy consumption for stir
