Problems solved by technology

[0003] The existing method is to use three-stage septic tanks for sewage treatment. Three-stage septic tanks have been widely used in sewage treatment methods. The sewage treated by three-stage septic tanks includes BOD, COD, NH4- Pollutants such as N have great removal efficiency, but the traditional three-stage septic tank does not have a good removal effect on rural high-P sewage, and adding post-treatment facilities alone will inevitably increase the cost of rural domestic sewage treatment, so The existing rural domestic sewage treatment equipment is still not perfect

Embodiment 1

[0029] see figure 1 , in an embodiment of the present invention, an integrated equipment for unpowered biologically coupled rural sewage treatment, including a sedimentation tank 1, a hydrolytic acidification tank 2 and a biologically coupled diafiltration tank 3, a sedimentation tank 1, a hydrolytic acidification tank 2 and a biologically coupled diafiltration tank The pool 3 can be buried underground to reduce space occupation. The sedimentation tank 1 is connected to the hydrolysis acidification pool 2 through the hydrolysis acidification water distribution pipe 5, and a combined filler 6 is arranged in the hydrolysis acidification pool 2. The biological coupling diafiltration The pool 3 is connected to the hydrolytic acidification pool 2 through the water distribution pipe 7, and a packing layer is arranged in the biocoupling infiltration pool 3, and the packing layer includes a planting cover layer 8 and a water distribution layer 9 arranged in sequence from top to bottom....

Embodiment 2

[0047] A rural sewage treatment system, including the unpowered biologically coupled rural sewage treatment integrated equipment described in Example 1.

[0048] The unpowered biological coupling rural sewage treatment integrated equipment has the following outstanding advantages:

[0049] 1) Sewage treatment has been realized for rural decentralized and individual households, and the treated water is stored in the sump for recycling;

[0050] 2) Realized the non-powered water intake and drainage of the high-load underground infiltration composite unit, the sewage load was greatly increased, and the effluent water quality was also better;

[0051] 3) A non-powered oxygen supply mechanism is set up to ventilate the high-load underground infiltration composite unit, which ensures the supply of oxygen to the system and realizes the coordinated progress of nitrification and denitrification reactions;

[0052] 4) The overall cost is low, the construction speed is fast, and it is m...

Abstract

The invention relates to the technical field of environment engineering sewage treatment and discloses powerless biological coupling rural sewage treatment integral equipment which comprises a settling pond, a hydrolysis acidification pool and a biological coupling diffusion cell, wherein the settling pond is connected with the hydrolysis acidification pool through a hydrolysis acidification waterdistribution tube; a combined filler is arranged inside the hydrolysis acidification pool; the biological coupling diffusion cell is connected with the hydrolysis acidification pool through a water distribution tube; a filler layer is arranged inside the biological coupling diffusion cell; the filler layer comprises a planting covering layer, a water distribution layer, a fine filtering layer, anair introduction layer, a refined filtration layer, a deep treatment layer and a water drainage layer. The equipment is low in construction cost, simple in structure, nearly free of operation cost, convenient to operate and high in treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental engineering sewage treatment, in particular to an integrated equipment for rural sewage treatment without power and biological coupling. Background technique [0002] At present, the domestic sewage in rural areas of our country is directly discharged, and finally converges into village ditches, fish ponds and lakes. This kind of untreated direct sewage exceeds the carrying capacity of natural water bodies, destroys the water body environment, and threatens drinking water safety in vast rural areas. In the hilly areas of central and western my country, rural households are scattered. This geographical distribution makes it difficult to collect sewage. At the same time, most rural households do not have complete sewage collection pipes and corresponding treatment facilities. Most of the sewage is untreated. The treatment is directly discharged, and these sewages have high N and P contents, an...
