Sewage treatment device

Abstract

The invention relates to a sewage treatment device. A body is separated into three cavities by a separation plate; the volumes of the three cavities are sequentially decreased from inside to outside;the flow rate of the sewage can be sequentially accelerated from inside to outside, so that the sludge accumulation can be sequentially increased from inside to outside; the effect of primarily eliminating silt is achieved; an atomization device is arranged on the surface of a micro filtering sieve screen; an atomization gas outlet is formed in the surface of the atomization device; a plurality ofbranch pipes are arranged in a box body cavity; a plurality of small branch pipes are arranged on the surface of the branch pipes; the branch pipes and an air inlet pipeline are connected; the air inlet pipeline is connected with an oxygen gas inlet pipe; harmful substances contained in the sewage are oxidized through oxygen gas; the atomization device is used for merging the sewage atomization and oxygen gas, so that the harmful substances are sufficiently treated; a micro sun burning filtering screen B is arranged in a purification chamber; an active carbon layer is arranged under the microsun burning filtering screen B; the sewage is further treated again, so that the safety is higher.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sewage treatment device. 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 ground runoff formed by urban precipitation carries a large amount of non-point source pollution into the river. 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 at river channel sewage outlets generally include engineering measures such as dredging, sewage interception, bank revetment, and aeration...

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 a palliative, not a permanent solution, 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
