Abstract

The invention discloses a rural domestic waste treatment device. Floc sludge is respectively placed in a pre-treatment region and a main reaction region; a guide region is arranged between the pre-treatment region and the main reaction region; a water outlet of the pre-treatment region automatically flows into the guide region and the main reaction region through a penetrating tube; a gas diffuser, a stirring device and a water outlet tube are arranged in each of the pre-treatment region and the main reaction region; the pre-treatment region and the main reaction region are connected through a hose; an adjustable partition plate is arranged in the main reaction region for realizing different functional regions of the main reaction region. According to the rural domestic waste treatment device disclosed by the invention, the problems of low efficiency, large floor space and high operation cost of an existing rural domestic waste treatment process are solved. The rural domestic waste treatment device has the advantages of good treatment effect, low operation cost, simple structure and the like. The rural domestic waste treatment device can be independently used and also can be in series connected for use, further can be used for upgrading and modifying the existing wastewater treatment facilities, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a wastewater biological treatment device, which belongs to the technical field of wastewater treatment equipment. Background technique [0002] In recent years, my country has made great progress in the treatment of urban water environment, and the urban water environment has been significantly improved. With the development of economy and the improvement of people's living standards, the problem of water environment pollution in rural areas of my country has become increasingly prominent. Due to the weak rural infrastructure and the lack of a complete sewage collection and discharge system, untreated sewage is directly discharged to nearby water bodies in street ditches, seriously polluting the water body environment, and farmland sewage irrigation and random flow are common. In order to improve the rural living environment and improve the quality of rural water environment, it is necessary to strengthen the treatment and disp...
