Problems solved by technology

[0002] The wastewater from the sintering plant usually needs to be pretreated in the neutralization coagulation tank, the sedimentation tank and the concentration tank before entering the purifier. When the wastewater enters each tank, it hardly flows, or the flow path is very short, which seriously hinders the suspension of the wastewater. Separation and removal of sediment, etc.

Abstract

The invention discloses wastewater pretreatment equipment, comprising a treatment basin. The treatment basin has a bottom wall, a front inner wall, a rear inner wall, a left inner wall and a right inner wall; the bottom wall is provided with a first guide plate extending up and out; one of the front inner wall and the rear inner wall is connected with the first guide plate, and the other and the first guide plate are provided with a guide opening therebetween. The first guide plate divides the treatment basin into a flow passage bending in a sinuous manner; wastewater flows in the flow passage along the first guide plate; the first guide plate helps prolong a flow path of the wastewater and thus quicken separation and removal of suspended matters, precipitates and the like.

Description

technical field [0001] The invention relates to a waste water pretreatment device. Background technique [0002] The wastewater from the sintering plant usually needs to be pretreated in the neutralization coagulation tank, the sedimentation tank and the concentration tank before entering the purifier. The wastewater enters each tank and hardly flows, or the flow path is very short, which seriously hinders the suspension of the wastewater. Separation and removal of precipitates, etc. Contents of the invention [0003] The problem to be solved by the present invention is to provide a wastewater pretreatment device that can speed up the separation and removal of suspended solids and sediments. [0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: a wastewater pretreatment device, including a treatment tank, the treatment tank has a bottom wall, a front inner wall, a rear inner wall, a left inner wall and a righ...
