Sewage treatment device for river sewage outlet

Abstract

The invention discloses a sewage treatment device for a river channel sewage outlet, which comprises a shell and a floating plate, the floating plate is placed on the upper part of the shell, and its edge extends out of the outer edge of the shell; The mud port is on the lower side of the water inlet; there is a cavity inside the shell, and the cavity is divided into three chambers by the first partition and the second partition, which are cement separation chamber, first filter chamber and The second filter chamber; the middle part of the cement separation chamber is provided with a filter layer, and the upper part of the cement separation chamber separated by the filter layer is filled with fillers, while the first filter chamber and the second filter chamber are filled with fillers; in the first compartment A filter is arranged between the plate and the floating plate, and a filter is also arranged between the second partition and the bottom plate of the casing. The sewage treatment device disclosed in the present invention adopts cement separation to improve the efficiency of sewage treatment; at the same time, it realizes on-site interception and degradation of pollutants in sewage, making the device a hydrophilic platform with the function of beautifying rivers.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device for a river sewage outlet. Background technique [0002] Urban river pollution is one of the major environmental and public health problems faced by most cities in my country. The main causes of urban river pollution include: (1) The urban sewage pipe network is not perfect, causing a large amount of domestic sewage to be directly discharged into the river without treatment; (2) The surface runoff formed by urban precipitation carries a large amount of non-point source pollutants into the river course. Therefore, controlling the discharge of pollutants into rivers from the source, that is, sewage treatment, is the key to controlling river pollution and improving river water quality. [0003] Existing sewage treatment devices for river sewage outlets generally include engineering measures such as dredging, sewage interception, bank revetment, and aeratio...

AI Technical Summary

Problems solved by technology

Due to incomplete interception or no interception measures at all, sewage is continuously discharged into rivers

Although ecological restoration measures can play a certain role in controlling river water pollution, these measures are basically methods that treat the "symptoms" rather than the "roots", and cannot fundamentally solve the problem of river pollution.

In addition, although the sewage treatment pipe project can completely solve the pollution problem caused by the direct discharge of sewage into the river, it is difficult to implement the sewage treatment plan in many urban areas, especially the old urban areas and suburban areas. That is to say, even if the sewage in these areas is intercepted, it is difficult to discharge into the sewage treatment plant for treatment
