Embodiment Construction

[0028] The following combination figure 1 , figure 2 and image 3 The present invention is described in further detail from the angle of water treatment process:

[0029] The urban sewage is sent to the pretreatment structure 2 through the water inlet pipe 1. Firstly, it can be pretreated through the grille 21 and the grit chamber 22 to remove the floating matter, suspended matter and sediment with large particle size, so as to avoid subsequent deflection The wetland filter is clogged. Then the sewage can adjust the water quantity and water quality through the regulating tank 23, and further remove suspended solids with larger particle diameters at the same time.

[0030] The pretreated raw sewage enters the baffled wetland filter group 3 through the pipeline. The baffle type wetland filter group 3 is composed of three filter tanks with a depth of 700-1000 mm arranged in a downward gradient. Each filter is provided with a vertical retaining wall 31, and a water flow chan...

Abstract

A system for treating sewage is composed of a pretreating construction, a deflection-type nunja filter pool group and a lateral underflow nunja bed group, which are arranged in gradient mode from high level to low level. Each filter pool contains a vertical retention wall, filler (haydite or zeolite) and aquatic plant. Said lateral underflow nunja bed group consists of multi-stage lateral underflow nunja bed, natural oxygen-aerating area and anaerobic stabilizing pond. Its method is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and environmental protection, and in particular relates to a sewage treatment system and a treatment method of a baffle wetland filter + a lateral underflow wetland bed. Background technique [0002] Through scientific and technological novelty search, there is no research literature report on the use of baffled wetland filter and lateral subsurface flow wetland bed technology to treat urban sewage at home and abroad, and there is no combination of baffled wetland filter + lateral subsurface flow wetland bed Related reports on technology treatment of sewage. [0003] The ecological treatment process using the "natural purification system" plays a role by recycling and utilizing the resources in the biological system. It is a low-cost, low-energy, simple and effective treatment technology combined with ecological landscape in sewage treatment. It is a desirable water pollution prevention ...
