Comprehensive decontamination method for forebay of pump station

Abstract

Provided is a comprehensive decontamination method for a forebay of a pump station. The comprehensive decontamination method comprises the following steps that (1), a rotary chain net trash remover ismounted on a water inlet of the forebay of the pump station, a chain plate type conveyor is mounted below the left side of the rotary chain net trash remover, a U-type screw conveyer is mounted in front of the edge of the front side of the upper portion of the forebay of the pump station, a movable dredging device is mounted above the forebay of the pump station, and a lifting type trash holdingdevice is mounted on each water gate on the rear side of the forebay of the pump station; (2), floating objects (algae) in water of a water inlet of the forebay of the pump station are collected and removed through the rotary chain net trash remover; (3), sludge in the forebay of the pump station is pumped and removed through the movable dredging device; and (4), the large floating objects in thewater of each water gate in the rear side of the forebay of the pump station are held up through the lifting type trash holding devices. According to the comprehensive decontamination method, decontamination is carried out in three parts, the quality of the water in the forebay of the pump station can be guaranteed, the water security of waterworks is ensured, and it is guaranteed that water conveying work of each conveying pipeline is conducted normally.

Description

technical field [0001] The invention relates to the technical field of decontamination of a pump station forebay, in particular to a comprehensive decontamination method for a pump station forebay. Background technique [0002] Usually, the water in the channel enters the forebay of the pump station through the water diversion port, and is transported by the pump station to the waterworks. Due to the characteristics of the forebay structure of the pump station, it is easy to form floating debris, and the bottom of the pool will continue to accumulate silt over time, and the pump will Larger floating objects (leaves, branches, plastic bags, etc.) that fall from the outside are easy to float in the forebay of the pumping station, which will affect the water delivery work of the pipelines behind the gates of the forebay of the pumping station. Contents of the invention [0003] The purpose of the present invention is to provide a comprehensive cleaning method for the forebay ...

[0002] Usually, the water in the channel enters the forebay of the pump station through the water diversion port, and is transported by the pump station to the waterworks. Due to the characteristics of the forebay structure of the pump station, it is easy to form floating debris, and the bottom of the pool will continue to accumulate silt over time. Larger floating objects (leaves, branches, plastic bags, etc.) that fall from the outside are easy to float in the front pool of the pumping station, which will affect the water delivery work of the pipelines behind the gates of the pumping station front pool
