A negative pressure sewage ecological treatment pool

Abstract

The application discloses a negative pressure sewage ecological treatment pool, which includes a main pool. The main pool is divided into: a water inlet section, a negative pressure section and a water outlet section. There are water inlet pipe, high-pressure air pipe and silt discharge pipe, and the high-pressure air pipe is connected to the high-pressure air source system; the upper part of the negative pressure section is provided with a negative pressure chamber, the lower port of the negative pressure chamber is located below the water surface, and the top of the negative pressure chamber is connected to the exhaust pipe. A water flow channel is set in the negative pressure chamber, and aquatic plant planting frames and aquatic plants are arranged in the water flow channel. The two ends of the water flow channel are respectively connected with the water inlet section and the water outlet section; , the overflow wall is located between the adsorption medium and the nozzle of the outlet pipe. The negative pressure sewage ecological treatment pool of this application has a small footprint, a large sewage capacity, and a shallow pool bottom, which can fully mix diatomite mud and sewage, and has a long ecological decontamination process, which can make the treated sewage meet the national discharge standards .

Description

technical field [0001] The application belongs to the technical field of sewage treatment facilities, and in particular relates to a negative-pressure sewage ecological treatment pool. Background technique [0002] Existing sewage treatment tanks generally use electricity to supply air to the sewage to increase oxygen. Due to the large volume of the sewage treatment tank, there will be a problem of insufficient dissolved oxygen. During the sewage treatment process, diatomite mud and silt generally accumulate at the bottom of the pond, and the diatomite mud and sewage are not mixed enough. Moreover, sewage treatment tanks generally occupy a large area. At present, every inch of land is very expensive, and the cost of occupying land for large-scale sewage treatment tanks is high. In order to reduce the floor area of ​​the sewage treatment tank without reducing the volume of the sewage treatment tank, the sewage treatment tank can only be built deeper, so that the bottom of t...

AI Technical Summary

Problems solved by technology

During sewage treatment, diatomite mud and silt generally accumulate at the bottom of the pond, and diatomite mud and sewage are not mixed sufficiently

Moreover, the sewage treatment tank generally occupies a large area

At present, the cost of land is very high, and the cost of occupying land for large-scale sewage treatment tanks is high

In order to reduce the floor area of ​​the sewage treatment tank without reducing the volume of the sewage treatment tank, the sewage treatment tank can only be built deeper, so that the bottom of the sewage treatment tank is difficult to transmit light and has insufficient dissolved oxygen

Moreover, the diatomite mud at the bottom of the pool is not mixed enough with the sewage, and the sediment is not easy to clean up. The end of the ecological decontamination process leads to a decline in the sewage treatment capacity of the sewage treatment pool.
