Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] like figure 1 As shown, the present invention includes an outer pool, and the outer pool is divided into a pre-sedimentation area, an anoxic area, a reaction area, and an air lift area from left to right by inserting plates; a facultative oxygen reaction module is set in the anoxic area, and a An aerobic reaction module, an air stripping module is arranged in the air stripping area.

[0017] The incoming water enters the pre-sedimentation zone 2 through the water inlet pipe 7 set on the outer pool 1 for initial solid-liquid separation to remove large suspended particles in the water; the pre-settled water enters the anoxic zone 3 through the insert plate 11; in the anoxic zone 3 Inside, the mixed liquid returned from the stripping zone 5 enters the facultative oxygen reaction module 14, and the reaction module 14 includes fillers for t...

Abstract

The invention discloses an integrated sewage treatment device, comprising an outer pool (1) which is divided into a pre-precipitation zone (2), an anoxic zone (3), a reaction zone (4) and gas stripping zone (5) from left to right by inserting plates (11); the outer pool (1) is provided with a water inlet pipe (7), a water outlet pipe (8) and a sludge discharge pipe (9); a?facultative?reaction module (14) is arranged in an anoxic zone (3); an aerobic reaction module (15) is arranged in a reaction zone (4); a gas stripping module (16) is arranged in a gas stripping zone (5); the upper parts of the aerobic reaction module (15) and the gas stripping reaction module (16) are provided with air pipes (12), which are connected with a fan (6); the lower part of the gas stripping module (16) is connected with the sludge discharge pipe (9), and the upper part of the gas stripping module (16) is provided with a mixed liquid return pipe (13); the mixed liquid return pipe (13) is connected with one end of a mixed liquor reflux tank (10); and the other end of the mixed liquor reflux tank (10) is connected with the facultative reaction module (14). The invention adopts a modular design with reasonable structure, so as to realize quick construction and installation, convenience for operation and maintenance and strong operability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an integrated sewage treatment device. Background technique [0002] While the development of industrialization and modern agriculture has created huge material wealth, it has also brought serious pollution to the water environment. As centralized sewage treatment solves the water pollution problem that people are concerned about, centralized sewage treatment has become the main way of urban sewage treatment. However, when carrying out large-scale centralized sewage treatment, the corresponding pipeline network construction must be carried out, which requires a huge pipeline network system and midway lifting pumping stations. The investment is huge, and the operation and maintenance costs are expensive. Centralized wastewater treatment is clearly unsustainable in terms of pollution spread. Sanitation and disposal systems are currently only available in wealthy countries. No ma...
