Sewage precipitation and purification control method for sewage plant

Abstract

The invention provides a sewage precipitation and purification control method for a sewage plant. The precipitation and purification method is realized based on inclined plate and inclined pipe precipitation equipment, the inclined plate and inclined pipe precipitation equipment comprises hanging support rods, top support connecting rods, threaded rods, vertical mounting rods, transverse support rods, positioning insertion rods, a mounting support frame and a spiral feeding pipe. The precipitation tank is integrally rectangular, a water baffle and a first spacing plate are welded to the rightside in the precipitation tank at an interval of crosspiece, the height of the first spacing plate is higher than that of the water baffle, and the tail end of the first spacing plate is not directlywelded to a bottom plate of the precipitation tank, and a water passing space exists between a bottom end face and a bottom plate of the precipitation tank. The spiral feeding pipe is disposed in theequipment, nozzles on the spiral feeding pipe are in spiral arrangement, and achieve synchronous jetting from top to bottom and jetting of a flocculant into a guide cylinder for uniform mixing with sewage, and then impurity pollution components in the sewage can be fully and massively separated out, thus improving the purification treatment effect of sewage.

Description

technical field [0001] This application is a divisional application of the Chinese invention patent application with the application number 201910273761.7 submitted on April 7, 2019, and the title of the invention is a kind of inclined plate and inclined tube sedimentation equipment used in sewage plants. Background technique [0002] Inclined tube sedimentation equipment refers to a sedimentation tank with inclined tubes in the sedimentation area. Inclined tube sedimentation equipment refers to a sedimentation tank with inclined tubes in the sedimentation area. There are two kinds of assembly forms: inclined pipe and branch pipe. In the sedimentation zone of the flat flow or vertical flow sedimentation tank, the inclined parallel pipes or parallel pipes (sometimes honeycomb packing can be used) are used to divide into a series of shallow sedimentation layers, and the treated and settled sediments are in each sedimentation shallow layer. Mutual movement and separation, the...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides an inclined plate and inclined tube sedimentation equipment used in the sewage plant to solve the problem that the feeding and mixing of the flocculant in the existing inclined tube sedimentation equipment is not uniform enough, resulting in a small amount of impurity precipitation, which affects the sewage purification effect , and the removal process of components such as inclined pipes is relatively cumbersome, and it is not convenient to remove for internal cleaning
