Sewage purification process for lake and river regulation

Abstract

The invention discloses a sewage purification process for lake and river regulation. A filtering tank is mounted at the top of an adsorption tank; a tank cover is arranged at the top of the filteringtank; a tank gate is mounted on the front side of the adsorption tank through bolts; a sealing gasket is arranged at the connecting part of the adsorption tank and the tank gate; the adsorption tank is positioned above a sterilization tank; the adsorption tank is mounted at the top of a support rack; the sterilization tank is mounted in the middle of the support rack; the adsorption tank communicates with the sterilization tank through a communicating tube; a feeding tube is arranged at the top of the sterilization tank; a water outlet tube is arranged at the bottom of the sterilization tank;and both the communicating tube and the water outlet tube are provided with valves. The sewage purification process has the advantages that integral purification operation of river sewage filtering, deodorization and sterilization is achieved, continuous production is achieved, and the river sewage purification efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of lake and river course management, and relates to a sewage purification process, in particular to a sewage purification process for lake and river course treatment. Background technique [0002] River sewage purification realizes the process of recycling water. [0003] The comparative document CN209507871U discloses a domestic sewage purification treatment device, including a water purification treatment box, the upper surface of the water purification treatment box is provided with a generator, a storage battery, a motor, a medicine inlet pipe and a circular through hole in sequence from left to right , the left side of the water purification treatment tank is provided with a water inlet pipe, a rectangular through hole and a dirt outlet pipe successively from top to bottom. Inside, there are four semicircular blades arranged in an array on the side of the first rotating shaft. The top of the first rota...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that the filtration efficiency of river sewage purification is relatively slow, which affects the speed of sewage purification in the later stage, resulting in a relatively slow overall purification speed of sewage; the fixed impurities produced by filtration need to be carried out intermittently Cleaning, and during the cleaning process, it is necessary to stop the purification equipment, and then the staff uses auxiliary tools to clean up the impurities accumulated in the filter cartridge, which not only affects the progress of the entire purification process, but also makes the purification device unable to continue production; When performing deodorization, activated carbon powder is usually directly added and stirred directly, so that the sewage needs to be re-filtered and cleaned in the subsequent process, and then the activated carbon powder is collected and cleaned, resulting in increased operating steps and increased labor; The mixing effect is not good, and the mixing is not uniform enough, and a sewage purification process for lake and river treatment is proposed
