Novel biochemical disinfection integrated device

Abstract

The invention relates to a novel biochemical disinfection integrated device, comprising an external fan, and a facultative zone, a self-aeration biological runner aerobic zone, an inclined plate settling zone and a disinfection function section which are sequentially connected, wherein the facultative zone is provided with partition plates; the facultative zone is divided into a plurality of zones by the partition plates, and diversion pipes are arranged among the zones; the self-aeration biological runner aerobic zone is provided with a self-aeration biological runner, bionic filler, particle filler, a bottom-perforated aerator pipe and an internal circulation pipeline; the inclined plate settling zone is provided with inclined plate filler, a three-phase separator, a stainless steel isolation net and an effluent weir trough; the disinfection function section is installed on a water outlet pipe. The novel biochemical disinfection integrated device solves the problem of a large boundary effect of bottom microporous aeration, has excellent sewage decontamination ability, and is simple and easy in system control operation, full in stirring of the particle filler and simple in structure of the disinfection function section.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a new type of integrated biochemical disinfection equipment. Background technique [0002] Some existing traditional sewage treatment equipment used in rural areas has a series of problems such as insufficient treatment effect, large area for the overall structure of the equipment, high operating cost, low system integration, complex control methods, and unattended operation. [0003] Chinese patent CN 204474501U discloses a new type of integrated rural sewage treatment equipment, but it has the following shortcomings: [0004] ①Using traditional microporous aeration, because the aeration method uses the traditional bottom microporous aeration method, for small water projects, the boundary effect is large, that is, if a small part of the aeration head is blocked or damaged, the water will be affected. The water quality has a very large impact, and the maintenance of the aeration...

AI Technical Summary

Problems solved by technology

[0004] ①Traditional microporous aeration is adopted. Since the aeration method adopts the traditional microporous aeration method at the bottom, for projects with small water volume, the boundary effect is large, that is, if a small part of the aeration head is blocked or damaged, the water outlet will be affected. The water quality is greatly affected, and the maintenance of the aeration head needs to completely drain the water in the area where the aeration head is located, and the maintenance workload is heavy

[0005] ②The MBR membrane process requires regular cleaning of the membrane, and the cleaning process is complicated and requires professional maintenance. The clear water needs to be pumped to be discharged, which is equivalent to adding a level of upgrade, and the operating cost is high.

[0006] ③The granular filler is placed in a fixed stainless steel mesh cage, and the granular filler is stirred only by aeration at the bottom, which cannot guarantee the mixing effect, the film removal effect cannot be guaranteed, and it is easy to form a dead zone

[0007] ④ There are many auxiliary equipment, difficult to operate and maintain, and professional technical personnel are required to be stationed for a long time
