Technical field
This utility model relates to sewage treatment area, and in particular, it relates to a kind of sewage disposal system.
Background technology
Sewage disposal is widely used in building, agricultural, the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, comes into the daily life of common people the most more and more.But, most sewage does not obtain appropriate process, but has been directly discharged into the regions such as river, the serious environment that have impact on periphery.The sewage quality that life or industry produce is complicated, and containing a large amount of antibacterials, virus, parasitic ovum and poisonous and harmful substance in sewage, conventional process mode is difficult to reach discharging standards.
A kind of sewage disposal system as disclosed in the Chinese patent that Authorization Notice No. is CN204727693U, it includes being sequentially connected logical former pond, mixing pit, sedimentation tank, filtering ponds and clear water reserviors, it is characterized in that, the side of described mixing pit is provided with chemicals dosing plant, described chemicals dosing plant is for adding medicament in described mixing pit, being provided with trapezoidal inclined tube body in described sedimentation tank, described filtering ponds are gravity type valveless water filter pond.When using above-mentioned sewage disposal system to carry out sewage disposal, sewage is successively via former pond, mixing pit, sedimentation tank, filtering ponds and clear water reserviors, in mixing pit, medicament is added by chemicals dosing plant, sewage is carried out pretreatment, sewage through pretreatment subsequently enters sedimentation tank, by the bulky grain in sewage and the Impurity removal of easily sedimentation, flows afterwards through filtering ponds, the residue in water can be removed further, reduce the turbidity of water.Trapezoidal inclined tube body it is provided with in the sedimentation tank of this sewage disposal system, effectively large granular impurity can be settled, and owing to filtering ponds are gravity type valveless water filter pond, i.e. use full-automatic waterpower control mode, when filtration resistance reaches certain value, can automatically carry out backwash, automatically into filtration condition after flushing, need not energy, there is obvious energy-saving effect.Sewage is after processing, it is possible to substantially removes the large granular impurity in sewage and little particle residue thing, reduces the turbidity of sewage.As mentioned above, this sewage disposal system is only capable of the large granular impurity removed in sewage, for molecule, its poor processing effect, so poor to the clean-up effect of sewage, and a large amount of antibacterials contained in sewage, virus, parasitic ovum etc. can not be effectively treated.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of sewage disposal system, and it can be effectively treated for a large amount of antibacterials contained in molecule and sewage, virus, parasitic ovum etc., good purification.
For achieving the above object, this utility model provides following technical scheme: a kind of sewage disposal system, including the rotational flow grit chamber being sequentially communicated, biochemistry pool, sedimentation tank, filter tank and sterilization pool, also include coarse rack and fine fack, described fine fack is positioned at the upstream of described rotational flow grit chamber, described coarse rack is positioned at the upstream of described fine fack, is provided with the first gas-liquid mixing pump in described sterilization pool, and described first gas-liquid mixing pump is communicated with ozonator.
By using technique scheme, coarse rack, fine fack, rotational flow grit chamber, biochemistry pool, sedimentation tank, filter tank and sterilization pool are capable of the precipitation to bulky grain thing, finely ground particles and purify, and the antibacterial in sewage, virus, parasitic ovum etc. can be effectively treated by biochemistry pool with sterilization pool, good purification.Ozonator pours into ozone in sterilization pool can sterilize and have the effect of deodorization to sewage, and, the ozone that the first gas-liquid mixing pump makes ozonator pour in sterilization pool is more abundant with contacting of sewage, and then makes its clean-up effect more preferable.
Being provided with the second gas-liquid mixing pump in rotational flow grit chamber it is also preferred that the left state, described ozonator has two gas outlets, and another opening of described ozonator connects with described second gas-liquid mixing pump.
By using technique scheme, ozonator can carry out preliminary treatment by the second gas-liquid mixing pump to the sewage in rotational flow grit chamber so that the clean-up effect of this system is more preferable.
It is also preferred that the left be provided with Flat Flow Final Settling Basin between described biochemistry pool and described sedimentation tank.
By using technique scheme, carrying out outside mud-water separation, also carry out sludge condensation, active sludge intermixture concentration is high (generally 2000-4000mg/L), has flocculability, belongs to stratification precipitation.Precipitation is to have interface clearly between muddy water, and floccule body combines overall common sinking.There is the effect that preferably precipitation purifies.
It is also preferred that the left be provided with Radial Flow Secondary Sedimentation Tank between described biochemistry pool and described sedimentation tank.
By using technique scheme, carrying out outside mud-water separation, also carry out sludge condensation, active sludge intermixture concentration is high (generally 2000-4000mg/L), has flocculability, belongs to stratification precipitation.Precipitation is to have interface clearly between muddy water, and floccule body combines overall common sinking.There is the effect that preferably precipitation purifies.
It is also preferred that the left be provided with Flat Flow Final Settling Basin and Radial Flow Secondary Sedimentation Tank between described biochemistry pool and described sedimentation tank, described Flat Flow Final Settling Basin is positioned at the upstream of described Radial Flow Secondary Sedimentation Tank.
By using technique scheme, its precipitation clean-up effect is more preferable.
It is also preferred that the left be provided with Flat Flow Final Settling Basin and Radial Flow Secondary Sedimentation Tank between described biochemistry pool and described sedimentation tank, described Radial Flow Secondary Sedimentation Tank is positioned at the upstream of described Flat Flow Final Settling Basin.
By using technique scheme, its precipitation clean-up effect is more preferable.
It is also preferred that the left described biochemistry pool includes anaerobic pond, anoxic pond and the Aerobic Pond being sequentially communicated, anaerobic pond is connected with rotational flow grit chamber, and Aerobic Pond is connected with sedimentation tank.
By using technique scheme, more comprehensive to dirty water purification.
This utility model has an advantage that this utility model can not only realize the precipitation to bulky grain thing, finely ground particles and purify, and the antibacterial in sewage, virus, parasitic ovum etc. can be effectively treated by biochemistry pool with sterilization pool, good purification.
