Description

A kind of aquaculture ecological purified water system
Technical field
The present invention designs sewage purification field, especially a kind of aquaculture ecological purified water system.
Background technology
Sewage typically refers to waste water centainly polluted, from life and production discharge.Sewage disposal (sewage Treatment, wastewater treatment), refer to the water quality for draining a certain water body to make sewage reach or reusing It is required that the process purified to it.Sewage disposal is widely used in building, agricultural, traffic, the energy, petrochemical industry, environmental protection, city The every field such as city's landscape, medical treatment, food and drink also come into the daily life of common people more and more.Sewage disposal is to make dirt Water, which reaches, drains a certain water body or process that the water quality requirement that reuses purifies it, and sewage disposal is widely used in Building, agricultural, the every field such as traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, food and drink are also come into and are sought more and more The daily life of the normal common people, classifies by sewage source, and sewage disposal is generally divided into production sewage treatment and sanitary sewage disposal, raw Production sewage includes trade effluent, rural sewage and medical sewage etc., and sanitary sewage is exactly the sewage that daily life generates, and is Refer to the complex mixture of various forms of inorganic matters and organic matter, including the size solid particle for floating and suspending, it is gluey and solidifying Gluey diffusate, pure solution are divided by the matter of water dirt, and it is natural pollution that the pollution of water, which has two classes, one kind, and another kind of is artificial Pollution, it is artificial pollution currently to endanger larger water body, and water pollution can be broadly divided into chemistry according to the difference of pollution impurity Contact scar, physical pollution and biologic contamination three categories, pollutant mainly have, unprocessed and discharge industrial wastewater, not The sanitary sewage discharged through processing largely uses the farmland sewage of chemical fertilizer, pesticide, herbicide, stacks Industry Waste by the river Gurry and house refuse, soil erosion, mine system engineering.
Many lakes and reservoir because nitrogen, phosphorus discharge caused by body eutrophication, seriously threaten the production and living of the mankind And the ecological balance.Existing sewage technique is to first pass through the raw sewage of coarse rack after sewage pump is promoted, by grid or Person's sand filter enters setting pot later, and the sewage by girt-water separation enters primary sedimentation pond, and above is coagulation (i.e. object Reason processing), the water outlet of primary sedimentation tank enters biological treating equipment, active sludge and biofilm, and biological treating equipment goes out Water enters secondary sedimentation tank, and the water outlet of secondary settling tank by disinfection discharge or enters tertiary treatment, coagulation terminate be to this Two stage treatment, tertiary treatment include biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, ion-exchange And electroosmose process.A sludge part for secondary settling tank is back to primary sedimentation pond or biological treating equipment, and a part enters sludge Concentration basin enters sludge digestion tank later, and by being dehydrated with after drying equipment, sludge is finally utilized.
To sum up, the prior art is mostly that drug is added into water treatment system so that separated from contaminants, which can be because The drug of addition generates secondary pollution, and needs during separated from contaminants to consume a large amount of energy.Therefore, there is an urgent need for one Kind environmental protection and lower-cost water cleaning systems.
