Description
Technical field
The invention belongs to Industrial Waste Water Treatments applied technical fields, and in particular to a kind of high stability for trade effluent
Processing system.
Background technique
Sewage refers to the general name of the water discharged in production and life activity, loses the original water for using function and is referred to as
Sewage, sewage are to cause aqueous metamorphism cannot be after continuation of insurance due to being mixed with new substance in water or because of the variation of external condition
Hold original use function.
The harm of water pollution is various, wherein the influence to human health is to cause acute and chronic poisoning, water
After body is polluted by toxic and harmful substance, poisoning just may cause by drinking-water or food chain, such as famous minamata disease, pain pain
Disease is as caused by water pollution；Carcinogenesis, certain chemical substances for having carcinogenesis such as arsenic, chromium, nickel, beryllium, aniline, benzo
(a) after pyrene and other polycyclic aromatic hydrocarbons, contaminated with halogenated hydrocarbons water body, it can be suspended object, bed mud absorption, it can also be in aquatic organism inner product
Tired, long-term drinking contains the water of this substance, or edible accumulation in vivo has the biology (such as fish) of this substance that may induce
Cancer；Occur using water as the infectious disease of medium.The biological pollutants polluted-water such as human and animal excreta may cause bacillary enteron aisle and pass
It catches an illness such as typhoid fever, dysentery, enteritis, cholera；Common virus such as gray nucleus viroid, Coxsackie virus, infectiousness in enteron aisle
Hepatitis virus etc. can all cause corresponding infectious disease by water pollution；It influences indirectly, after water pollution, can often cause water
Sensory properties deteriorates, and such as certain pollutants are under a certain concentration, though water generation can be made different without directly endangering the health of people
It is smelly, heterochromatic, foam and oil film etc. is presented, interferes the normal utilization of water body.The substances such as copper, zinc, nickel can inhibit under a certain concentration
The growth and breeding of microorganism decline water body self-purification ability to influence the decomposition and biological oxidation of Organic substance in water, influence
The sanitary condition of water body.
Water pollution can both seriously endanger the ecosystem, can also cause serious economic loss, so current water pollution
Improvement has attracted people's attention, and before the sewage such as production, life are discharged, needs to carry out a series of processing, so that
Its standard for reaching discharge.
Currently, for producing the processing system of trade effluent, design it is unreasonable, cannot be in efficient, high-quality removal sewage
The mixed harmful substance of institute and solid sundries etc., i.e., production Industrial Waste Water Treatments quality is low, the sewage treatment time is long, at high cost
Deng.
Therefore, based on the above issues, the present invention provides a kind of high stability processing system for trade effluent.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of high stability processing system for trade effluent, designs
Rationally, stable working state and harmful substance such as COD, NH3-N, T-N in sewage can efficiently be removed etc., improves sewage treatment effect
Rate and processing quality, shorten the processing time of sewage, reduce cost.
Technical solution: the present invention provides a kind of high stability processing system for trade effluent, including sequentially connected
Conditioning tank, grille well, aerated grit chamber, hybrid reaction sedimentation basin, mixing distribution reservoir, BBR device, aeration tank, secondary settling tank, turntable
Filtering cloth filtering pool, ultraviolet disinfection canal, reuse or discharge；Sewage is evacuated to sediment by aeration by installation sewage pump in the grille well
Pond；The sewage is successively carried out different procedures processing by above system component parts, and by final reuse or discharge.
The technical program, the BBR device is biofilm processing, by being attached on BBR device medium surface
Organic matter, ammonia nitrogen and phosphate in the absorption of Bacillus bacterium and decomposition water inlet, reach 40-75% to the removal rate of organic matter.
The technical program, the grid slag in trade effluent is screened out outward transport by the grille well, and the aerated grit chamber will
Sand setting in trade effluent screens out outward transport, and flocculant, the mixing water distribution is added when handling operation in the hybrid reaction sedimentation basin
Nutrient solution is added in pond when handling operation, air is added when handling operation in the BBR device, aeration tank.
The technical program, the hybrid reaction sedimentation basin is connect with thickened sludge pond, thickened sludge pond and sludge dewatering
Machine connection, the mud cake outward transport handled through dense sludge dewatering equipment.
The technical program, the aeration tank, secondary settling tank are connect with mixing distribution reservoir respectively, and the interior reflux of aeration tank is dirty
Water, secondary settling tank returned sludge be back to respectively mixing distribution reservoir carry out circular treatment again.
Compared with prior art, a kind of beneficial effect of the high stability processing system for trade effluent of the present invention exists
In: it designs reasonable, stable working state and can efficiently remove harmful substance such as COD, NH3-N, T-N in sewage etc., improves
Sewage treating efficiency and processing quality, shorten the processing time of sewage, reduce cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of high stability processing system for trade effluent of the invention；
Fig. 2 is a kind of water outlet detection data of high stability processing system for trade effluent of the invention.
