Embodiment Construction
[0013] The present invention is an assembled three-dimensional type A for rural decentralized sewage treatment 2 / O reaction tank, including anaerobic zone 1, anoxic zone 2, aerobic zone 3 and precipitation zone 4.
[0014] Each area is an independent unit, and the top of the shell of each independent unit is provided with a flange, which is connected in series from bottom to top through the flange. The areas are fixed with screws and leak-proof gaskets are installed. .
[0015] The tank body described above adopts a stainless steel structure with a thickness of 5-10mm, and the different units are separated by partitions, which are a stainless steel structure with a thickness of 5mm.
[0016] The above-mentioned anaerobic zone 1 is provided with a water inlet 7 and a sludge return port 9. The sludge return port is connected to a sludge return pump 29 through a pipeline, and a top cover is provided on the top of the anaerobic zone to play a sealing role.
[0017] The above-mentioned an...

Abstract
The invention relates to an assembled stereoscopic A2 / O reaction tank for rural dispersible sewage treatment and in particular relates to an assembled stereoscopic nitrogen and phosphorus removal device applicable to rural dispersible domestic wastewater treatment and a treatment method thereof. The assembled stereoscopic A2 / O reaction tank is characterized in that an A2 / O process is adopted, the whole reaction tank is wholly in a cylindrical structure, four units, namely an anaerobic zone, an anoxic zone, an aerobic zone and a settling zone, are sequentially arranged from top to bottom in a serial splicing mode, and the device is miniature and small in floor space. Each unit of the device is independent, and the device is compact in structure, convenient to mount, detach and maintain. The reaction tank adopts the A2 / O process, fine bubble aeration is adopted in the aerobic zone, and stereoscopic flexible stuffing is hung, so that the system is stable in operation and high in purification efficiency. By adopting the A2 / O process, the integrated domestic wastewater treatment device is high in integration degree, compact in structure, good in treatment effect, small in floor space and easy and convenient to detach and maintain, and a novel technical scheme is provided for rural domestic wastewater treatment in vast rural areas, particularly mountainous areas.
Description
Technical field: [0001] The invention belongs to the technical field of sewage treatment, and is specifically an assembled three-dimensional type A for rural decentralized sewage treatment. 2 / O reaction tank. Background technique: [0002] There are nearly 800 million farmers living in the rural areas of our country, and more than 600 million farmers have basically achieved drinking water safety, but the rural drainage situation is not optimistic. 96% of the villages do not have complete drainage channels and sewage treatment systems. The main discharge method of domestic sewage is directly sprayed on the ground, untreated or simply treated in a septic tank, then discharged into the nearby river or into the river through the sewer, etc., making the water pollution more and more serious. The requirements for control are getting higher and higher. In this context, our country has put forward the huge historical task of building a new socialist countryside and clarified the requir...
