Small town sewage treatment multifunctional integrated equipment

Abstract

The invention relates to small town sewage treatment multifunctional integrated equipment, which includes a reaction tank, a host above the reaction tank, a main shaft connected to the host output end, and an aeration component, a stirring component and a mud scraping component that are disposed on the main shaft from top to bottom in order. The main shaft consists of the rotation shafts of the aeration component, the stirring component and the mud scraping component together. The host comprises a double speed motor, a speed reducer connected to the output shaft of the double speed motor, and a frequency conversion control cabinet for controlling the double speed motor. Specifically, the aeration component is used for realizing the aeration function so as to complete organic matter degradation and ammonia nitrogen nitrification of the reaction tank water body; the stirring component is used for realizing the mixing function so as to complete nitrogen removal by denitrification of the organic carbon source in the reaction tank water body; and the mud scraping component is used for realizing the mud scraping function so as to complete discharge of mud sinking at the reaction tank bottom. The equipment provided by the invention can serve several purposes, and finishes multiple sewage treatment processes in the same reaction tank, thus having very high promotional value for small town sewage treatment.

Description

technical field [0001] The invention relates to equipment for sewage treatment biochemistry and sludge discharge technology, in particular to equipment integrating the functions of stirring, aeration and mud scraping, and is especially suitable for scattered point source sewage treatment equipment in small towns in rural areas. Background technique [0002] With the acceleration of urbanization in rural areas, the problem of water pollution has become increasingly prominent, and has become a new hot spot after sewage treatment in large and medium-sized cities. Its effectiveness will directly affect the overall condition of my country's water environment and the quality of harmonious development between man and nature. Sewage treatment in small rural towns in my country really originated from the treatment of the Three Gorges Reservoir area, and it is worth analyzing and thinking about the existing difficulties and problems so far. Due to historical reasons, the infrastructu...

AI Technical Summary

Problems solved by technology

The continuity of the sewage treatment oxidation ditch process is not suitable for the current situation of unstable sewage water in small towns, and the bottom aeration of the sewage treatment SBR process is not suitable for the current situation of large differences in small town sewage water quality. Therefore, these two mature processes are used in small towns. Sewage treatment has been severely restricted
