Description
Technical field
The present invention relates to technical field of sewage, more particularly to a kind of integrated rural domestic sewage processing method.
Background technology
Mainly there are kitchen, shower in the source of domestic sewage in rural areas, wash and flush the toilet, its quantity, composition, pollutant concentration
Habits and customs, living standard and water consumption with urban residents are relevant.In general, domestic sewage in rural areas has following features：
Content of organics is higher, and biodegradability is good, and the poisonous and harmful substance content such as heavy metal is low, and water quality and quantity fluctuation is big.
Through retrieval, the A of Chinese patent application publication No. CN 107200432 are disclosed at a kind of integrated rural sanitary sewage
Reason method, including：S1, sewage is discharged into the coarse grid room being sequentially arranged from inside to outside；S2, the sewage for treating coarse grid room
Thin grid room is discharged into, row buffering regulation is entered to sewage；S3, by overflow manner, the water after being handled in thin grid room is discharged into MBR
Film process room；S4, by overflow manner, the water after being handled in MBR film process room is discharged into oxidizing chamber；S5, at thin grid room bottom
Portion sets the first mud discharging mouth, and the second mud discharging mouth is set in MBR film process room bottom, and the 3rd mud discharging mouth is set in oxidizing chamber bottom,
Three mud discharging mouths lead to the mud room of chambers bottom, and mud room is used to accept the sludge in sewage.
The characteristics of country sewage emission source is that discharge capacity is little, and emission point disperses, and sewage is collected by extensive pipe network
Medium-and-large-sized sewage treatment plant is concentrated to have any problem, and it is uneconomical.But be such as allowed to free discharge, then larger shadow is caused to environment
Ring, existing sewage disposal process is comparatively laborious, and processing cost is higher, and operating efficiency is relatively low, and treatment effect is good.
The content of the invention
It is an object of the invention to provide a kind of integrated rural domestic sewage processing method, possesses cost of sewage disposal
Low, the advantages of operating efficiency is high, high treating effect, solve that existing sewage disposal process is comparatively laborious, processing cost is high, work
The problem of efficiency is low.
A kind of integrated rural domestic sewage processing method according to embodiments of the present invention, specifically comprises the following steps：
S1：Sanitary sewage is filtered for the first time by grid solarium；
S2：The sewage treated by grid is discharged into setting pot, carrying out sedimentation separation to the sand in sewage goes
Remove；
S3：The sewage treated by setting pot is drained into first shallow lake pond, the sludge in sewage separate removing；
S4：The process sewage that just shallow lake pond treats is drained into biological treatment tank and handled；
S5：The sewage treated by biological treatment tank is drained into secondary sedimentation tank, the sludge in sewage is carried out
Secondary precipitation；
S6：The sewage treated by secondary sedimentation tank is drained into coagulating sedimentation tank, added in coagulating sedimentation tank
CuSO4, per 1000m31.5-3 ㎏ CuSO is added in sewage4, the debris in sewage is precipitated again；
S7：The sewage treated by coagulating sedimentation tank is drained into filtering tank and carries out filtration treatment；
S8：After adding disinfectant in the liquid after filter tank filtering, the concentration for adding disinfectant is 0.15-0.30 ㎎/L.
On the basis of such scheme, after being precipitated in S3 to the sludge in sewage, logistics is flowed into slurries filter
Filtered, the sludge after filtering is flowed into mud concentration tank and concentrated.
On the basis of such scheme, after secondary to the sludge progress in sewage in S5, partial sludge flows again into life
Handled in thing process tank, excess sludge is flowed on slurries filter and filtered, and the sludge after filtering is flowed into mud
Concentrated in concentration tank.
On the basis of such scheme, the sludge after the mud concentration tank concentration is sent to slurry dewatering tank and is dehydrated.
On the basis of such scheme, in S8, the composition of used disinfectant is ClO2。
On the basis of such scheme, the temperature control of liquid is at 4 DEG C -6 DEG C when disinfectant is added in S8.
The present invention has an advantageous effect in that compared with prior art：
1st, can be respectively to miscellaneous in sewage by setting grid solarium, setting pot, biological treatment tank and secondary sedimentation tank
Thing and sand carry out preliminary filtering, and sewage, which is sent in biological treatment tank, effectively to carry out biological treatment to sewage,
Environment is protected, sets secondary sedimentation tank to carry out secondary precipitation to the impurity in sewage, it is simple and effective to remove in decontaminated water
Impurity, add CuSO in coagulating sedimentation tank4The cuprous iodide sediment of the iodide ion generation white in decontaminated water can be removed,
The debris in decontaminated water, high treating effect can effectively be removed.
2nd, by setting filtering tank to be filtered again to the sewage for removing debris, added in sewage after filtration
Disinfectant can remove the bacterium in decontaminated water, can be effectively to precipitation by setting mud concentration tank and slurry dewatering tank
Sludge is concentrated and is dehydrated, and the sludge after the processing of slurry dewatering tank can be used for filling, is agricultural and make compost, and protect
Environmental beneficial effect, reduce the cost of sewage disposal.
