Problems solved by technology

The traditional three-format septic tank has dead angles due to underutilization of the volume, and it is difficult to effectively mix sewage and activated sludge, and the treatment efficiency for sewage treatment is low
On the other hand, due to the low temperature, the sewage treatment effect is worse in winter

Abstract

The invention discloses an unpowered mixing and low temperature resistant biochemical treatment device for rural (community) sewage mud liquid, and the device includes a floating precipitation separation pool, a baffle mixed fermentation pool and an efficient biochemical treatment pool. The middle of the floating precipitation separation pool is communicated with the baffle mixed fermentation tank through a stream guidance tube, the upper part of the baffle mixed fermentation tank enters into the bottom of the efficient biochemical treatment pool through a three-way stream guidance tube, and the upper part of the efficient biochemical treatment pool through a stream guidance tube enters into a depth treatment facility or external environment. The baffle mixed fermentation tank is provided inside with a baffle plate, and stereo elastic packing suitable for biological biofilm culturing is suspended in the efficient biochemical treatment pool. The invention optimizes the process of a traditional three-case septic tank, extends the residence time of waste water, improves the degree of mixing of sewage and activated sludge, utilizes the geothermal to improve the treatment effect of sewage in winter, and has the characteristics of low cost, low operation cost, high efficiency, and easy popularization.

Description

technical field [0001] The invention relates to a biological anaerobic fermentation treatment system capable of biochemically treating sewage in the field of environmental protection engineering, in particular to a non-powered mixing, anti-low temperature biochemical treatment device and treatment method for rural (community) sewage sludge. Background technique [0002] In recent years, with the advancement of new rural construction and urbanization, a large number of villages and small towns similar to urban communities have emerged in rural areas, and there is an urgent need for new environmental protection facilities to deal with relatively centralized decentralized domestic sewage. [0003] Due to the significant advantages of anaerobic technology in terms of energy saving, material and energy recovery, the anaerobic biological treatment technology of wastewater has become the core technology of sustainable development. [0004] Anaerobic biological treatment technologie...
