Modularized underground sewage treating system based on cylindrical precast element

Abstract

The invention relates to a modularized underground sewage treating system based on a cylindrical precast element. The system comprises a grating filtering module, a preprocessing module, a biochemical treatment module, a secondary treatment module and a sludge processing module, a water outlet of the grating filtering module is connected with a water inlet of the preprocessor module through pipelines and a pressure pump, a water outlet of the preprocessing module is connected with a water inlet of the biochemical treatment module through pipelines, a sludge outlet of the preprocessing module is connected with a sludge inlet of the sludge processing module through pipelines, a water outlet of the biochemical treatment module is connected with a water inlet of the secondary treatment module, a sludge outlet of the biochemical treatment module is connected with the sludge inlet of the sludge processing module, a sludge outlet of the secondary treatment module is connected with the sludge inlet of the sludge processing module, a standard water discharge port is arranged on the secondary treatment module, and a sludge outlet is arranged on the sludge processing module. The present invention has advantages of scientific design, simple structure, small occupation area, short construction cycle, low construction cost, safety and reliability.

Description

technical field [0001] The invention belongs to the field of underground sewage treatment systems, in particular to a modular underground sewage treatment system based on cylindrical prefabricated components. Background technique [0002] With the rapid development of my country's economy, the process of urbanization is further accelerated, the scale of cities is expanding day by day, and the amount of sewage discharge is rising rapidly, which puts forward higher requirements for the capacity of urban sewage treatment. The existing sewage treatment facilities are relatively backward, and there are disadvantages such as large area, limited sewage treatment capacity, backward traditional sewage treatment technology, pollution of the surrounding environment by the above-ground sewage treatment facilities, and affecting the quality of life of the surrounding residents. A series of issues such as equipment transformation and pipeline network supporting construction. According to...
