Modular distributed sewage treatment device and construction method thereof

Abstract

The invention discloses a modular distributed sewage treatment device comprising a box body and a function module; the box body comprises a main body part, a front end plate, a rear end plate and a cover plate; a plurality of guide rail sets are arranged on the main body part; first guide grooves are formed in the functional module; the first guide grooves are formed in two side surfaces and the bottom surface of the functional module in an extending manner; the front end plate and the rear end plate are provided with second guide grooves respectively, the front end of the main body part is provided with a first table top, the rear end of the main body part is provided with a second table top, the first table top is provided with a third guide groove, and the second table top is provided with the guide rail sets. The invention further discloses a construction method of the modular distributed sewage treatment device. Modular design is adopted; the functional module is inserted and positioned on the box body through matching of the first guide grooves and the guide rail sets, when the types of accepted residents are changed, the types, the number and the arrangement sequence of thefunction module can be flexibly adjusted according to different inlet water quality conditions, and meanwhile, when the function module breaks down, the fault function module can be conveniently takenout to be overhauled or replaced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a modularized decentralized sewage treatment device and a construction method thereof. Background technique [0002] The decentralized sewage treatment device is a domestic sewage treatment device set up for relatively scattered residential areas. It can divert the domestic sewage that is inconvenient to be collected to the sewage treatment plant for centralized treatment. It has a small volume and corresponds to various types of users. Features. [0003] Since each decentralized sewage treatment device accepts a very small number of residential users, the composition of the personnel who accept users has a great impact on the quality of the influent water (the quality of domestic sewage). Flushing sewage and washing water are mainly used, the water quality is relatively weak, and the concentrations of COD and TN are not high. A little treatment can meet the discharge s...

Problems solved by technology

[0004] At the same time, with the passage of time, the types of residents accepted by decentralized sewage treatment plants often change. The existing decentralized sewage treatment plants are all fixed structures, which cannot be flexibly adjusted according to different influent water quality conditions, such as The type of residents accepted during installation is mainly the elderly. After a period of time, the proportion of young and middle-aged residents will increase, and the water quality will exceed the standard. If the type of residents accepted during installation is mainly young and middle-aged, after a period of time, the residents will be elderly If the ratio increases, it will cause waste of resources

In the face of changing influent water quality, there are certain limitations in adopting a fixed-structure decentralized sewage treatment device, which often cannot achieve good application results

[0005] Furthermore, since the existing distributed sewage treatment device is a fixed structure, when it breaks down, the disassembly and maintenance process is very cumbersome
