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

The invention relates to sewage treatment processes and particularly relates to a reaction tank integrating denitrification, nitrification, water discharging and sludge discharging. The reaction tank is a circular building. A combined device is disposed in the center of the tank, and is formed by coaxially connecting a stirring part, an aeration part and a sludge scraping part, wherein the three parts rotate at different speeds and different directions and complete different functions. A water inlet channel and a water outlet are disposed in the periphery of the tank. The water inlet channel is connected to a water feeding pump. An effluent weir is disposed at the water outlet and is an electric downward-opening type plate-laminated valve, wherein a wedge plate is opened downward, and supernatant overflows from the top. The bottom of the reaction tank is provided with a sludge collecting pit. The sludge collecting pit is connected to a sludge pump to discharge sludge. The whole process of the reaction tank can adopt liquid-level, dissolved oxygen and time control. A plurality of sewage treatment steps can be completed automatically in the reaction tank. The reaction tank is suitable for dispersive point source sewage treatment in countryside and small towns, and has a wide application prospect.
Description
technical field [0001] The invention relates to equipment for sewage treatment biochemical and sludge discharge processes, in particular to a reaction pool integrating denitrification, nitrification, water discharge and sludge discharge, and is especially suitable for scattered point source sewage treatment 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 inf...
