Description
Technical field
Municipal wastewater processing technology field is the utility model is related to, is more particularly to a kind of with the municipal administration of multistage impurity removal function
Use sewage disposal system.
Background technology
Sewage disposal is exactly to the various economy of city domestic sewage and industrial wastewater, rationally.The effective work of science
Process, sewage disposal be widely used in municipal administration, building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment,
The every field such as food and drink.
With the rapid development of China's economy, China's water environmental problems become increasingly conspicuous, and town and country water environment has in various degree
Pollution.Seriously degenerated because of pollution, its ecosystem in town and country river course.River water quality is deteriorated, and most river water bodies are seriously polluted, rich
Nutrient laden, water hypoxia, blackening are fouled, and cause the Environmental situations of sternness.
Urban sewage treatment process is typically according to the utilization of municipal sewage or emission direction and considers the self-purification of water body
Ability, the degree for the treatment of of sewage and corresponding handling process are determined, the sewage after processing, no matter is used for industry, agricultural either
Recharge recharge of groundwater, it is necessary to meet the oil pipe water standard that country issues.Modern sewage disposal technology is according to processing journey
Degree division, can be divided into one-level, two level and tertiary treatment process.Sewage coagulation Applied Physics method, such as sieving, precipitation are gone
Except undissolved suspended solid and floating substance in sewage.Sewage second-level processing mainly applies bioremediation, that is, passes through
The metabolism of microorganism carries out the process of material conversion, and the various complicated oxidation operations in sewage are degraded to simply
Material.Biological treatment has certain requirement to the dissolved oxygen amount in sewage quality, water temperature, water, pH value etc..Tertiary sewage treatment be
On the basis of I and II processing, it is difficult in sewage to be removed using the physics such as coagulation, filtering, ion exchange, counter-infiltration, chemical method
The nutritional substances such as the organic matter of dissolving, phosphorus, nitrogen.Groups of contaminants in sewage is into extremely complex, it is often necessary to several sides above
Method combines, and can be only achieved processing requirement.Sewage coagulation is pretreatment, and two stage treatment is main body, and the sewage after processing is general

Sewage second-level treatment plant, to solve the water pollution problems of getting worse.Municipal wastewater treatment technology mainly has biological at present
Oxidizing process, activated sludge process, biofilter etc., but due to municipal sanitary sewage impurity seriously spread unchecked and existing sewage at
The backwardness of the simple and technology of flow is managed, is caused in actual motion processing procedure to the treatment effect wretched insufficiency of sewage, place
Serious poisonous and harmful and condensation product still be present in the sewage after reason；
In order to solve the above problems, Application No.：201610794084.X patent is entitled：A kind of sewage disposal system
Patent discloses a kind of device of sewage disposal, but the processing equipment investment in this technology to municipal wastewater is larger, operation
Cost is too high, is not suitable for promoting the use of.
In addition, existing down-stream processing unit, only the residual husky, profit in water is handled, and it is right
Metallics in water could not timely separating treatment, can not reclaim and utilize for metal, cause to waste, can usually block out
The position at the mouth of a river, existing device is only simple sewage disposal in addition, and dynamics is not powerful enough, it is impossible to reaches draining water quality
Standard.For this reason, it may be necessary to design a kind of new sewage disposal system, above-mentioned sewage of the prior art can be comprehensively overcome
It is insufficient existing for processing system.
Utility model content
The purpose of this utility model be to provide it is a kind of there is multistage impurity removal function municipal administration sewage disposal system, solved with this
Certainly after the standard simple, backward in technique, that draining water quality can not be reached of waste water processes present in prior art, processing
Still there is the problems such as serious poisonous and harmful and condensation product in sewage, by setting multistage sewage disposal system, baffling iron removaling
