Water outlet 17 is fixedly mounted on the right side of the clarifier-tank 15.
A kind of technique of economic benefits and social benefits denitrogenation dephosphorizing the following steps are included:
Step 1: the foul gas respectively generated in processing structures, is sent under the action of pump orifice, conveying air hose and blower
Spray column carries out primary treatment.Odorous gas comes into full contact with water, and the stench particle in air is only absorbed by the water and removes.At the same level
Reason system (main function: by particulate matter, floccule, hydrogen sulfide, ammonia, acid waste gas and the solution soluble easily in water in foul gas
Ingredient)；
Step 2: by spray column treated exhaust gas, handle by drier (main function: the floccule in exhaust gas is intercepted,
And the moisture content in exhaust gas is taken off to 85% to the normal operation hereinafter, to guarantee lower one for the treatment of process)；
Step 3: being sufficiently disengaged from the moisture content in exhaust gas by drier, then handled by UV photodissociation device.It is ultraviolet in C-band
It under light irradiation, send to composite photocatalyst metallic nickel net unit, under the ultraviolet light irradiation of C-band, forming TiO2 photochemical catalytic oxidation is
Activity hydroxy (OH) and other active oxidation substance (O2-, OOH, H2O2) coefficient results.It is raw on the surface TiO2
At OH group reactivity it is very high, there is the reaction energy for being higher than all kinds of chemical bond energys in organic matter, add O2-, OOH,
The synergistic effect of H2O2 active oxidation substance, can quickly and effectively decomposing organic matter.(main function: remove a part of exhaust gas
In benzene,toluene,xylene, non-methane total hydrocarbons and VOCs, and unstable organic principle is decomposed)
Step 4: the exhaust gas after the decomposition of UV photodissociation device enters biological deodorizing filter tank and further absorbs organic point that goes removing exhaust gas to have
Son.Absorption, suction of the foul smell by wet, porous and full of active microorganism filtering layer, using microbial cell to odorant
Receipts and degradation function, resolve into the simple inorganic matter such as CO2, H2O after odorant is adsorbed.(main function: further removal is useless
Organic principle in gas, it is ensured that VOCs qualified discharge).
Maximum discharge (15m or more height) is drawn by chimney step 5: being handled exhaust gas up to standard.
The working principle of the invention:
In use, sewage outlet is connect with oxidation ditch anaerobic pond 1, sewage is made to enter water inlet pipe 2, in no dissolved oxygen and nitre
Under anaerobic condition existing for state nitrogen, the organic matter in sewage is decomposed by anaerobic bacteria, metabolism, is digested, so that organic in sewage
Object content is greatly decreased, and several biologic packing material filter screens 4 are equipped in water inlet pipe 2, and reticular structure can increase water body and anaerobic bacteria
Contact area, increase Anaerobic Treatment efficiency.Later, sewage enters anoxic pond 5, with the denitrifying bacteria in anoxic pond 5 by nitre
Hydrochlorate and organic matter are removed by denitrification, to reach denitrogenation and remove the dual purpose of COD, sewage is through anoxic pond 5
Enter aerobic tank 7 afterwards, sewage circular treatment in aeration zone aeration tank 8 is divided oxidation operation in sewage by aerobic bacteria
Solution enters ecological pool 11 at more stable inorganic matter later, and the water surface of ecological pool 11 is equipped with artificial ecology floating bed 12, utilizes water
Plant carries out absorption point to elements such as nitrogen, phosphorus, and the root system of plant has huge specific surface area, is micro- in water body
Biology provides good carrier, plays the role of biofilm carrier, can be good at adsorbing suspended material, Er Qiezhi
Object root system can also be enriched with a series of heavy metal element and organic pollutant in water body, achieve the purpose that purification of water quality；So
Sewage enters mud-water separation pond 13 afterwards, further diverges to the sludge impurity in sewage, finally enters clarifier-tank 15, utilizes
Carbon net 16 carries out last time filtering to sewage, is discharged therewith by water outlet 17.
Finally it is pointed out that above embodiments are only the more representational examples of the present invention.It is clear that the invention is not restricted to
Above-described embodiment, acceptable there are many deformations.Any letter to the above embodiments according to the technical essence of the invention
Single modification, equivalent variations and modification, are considered as belonging to the scope of protection of the present invention.
