Between 200mg/l, it is necessary to advanced treating is carried out using appropriate technology, further to reduce the indexs such as COD, SS, colourity.Mesh
Before, the application on wood-based plate Sewage advanced treatment is few, has indivedual enterprises by increasing single coagulation after biochemical treatment
Precipitation or increase sand filtration, also some enterprises add Fenton reagent in advanced treating, otherwise the processing of these methods does not reach standard
It is required that or larger operating cost is produced, operational administrative is also more complicated.Lack complete set can stable operation, behaviour
Facilitate, operating cost is low, strong shock resistance, and and can makes water outlet reach the system and technique chain of standard.
Authorization Notice No. CN104261634B, the utility model patent of entitled " a kind of wood-based plate Waste Water Treatment ",
Disclose it is a kind of since original sub-block to advanced treating a whole set of wood-based plate wastewater treatment flow process, in advanced treating
During employ the steps such as coagulating, ozone oxidation, although to a certain extent can be preferably to high-concentration hardly-degradable
Organic wastewater handled, but still exist cannot ensure handled water reach higher discharge standard (particularly COD,
That is COD standard), it is also difficult to control it to realize continuous discharge in the case of standard stabiliser.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of not only easy to operate, operation
Expense is low, strong shock resistance, and and can makes water outlet reach the wood-based plate advanced waste treatment systems of high standard stable emissions.
A kind of wood-based plate advanced waste treatment system, including coagulation reaction tank and ozone-oxidizing device, at secondary biochemical
In wood-based plate waste water access coagulation reaction tank after reason；The water side access inclined-plate clarifying basin of the coagulation reaction tank, ozone oxygen
Makeup is put to connect with the supernatant outlet of inclined-plate clarifying basin, the water side access BAF of ozone-oxidizing device, exposes
Decolouring pond is accessed after the filtered device in water side of gas biofilter, water outlet up to standard is offered in decolouring pond.
Further described as to above-mentioned technical proposal：
Mixing and flocculation stirring machine are provided with the coagulation reaction tank.
Further described as to above-mentioned technical proposal：
PVC swash plates and effluent weir are provided with the inclined-plate clarifying basin.
Further described as to above-mentioned technical proposal：
Filtrate employed in the BAF is ceramic grain filter, ceramic grain filter height 3.0-3.5m, crosses filtering velocity
Spend 2-4m/h.
The utility model is given birth to by the efficient combination of six processing units such as coagulation reaction tank in wood-based plate waste water through two level
After change processing, the indexs such as the organic matter, suspension, colourity of water outlet are effectively reduced, water outlet is as clear as crystal, can qualified discharge or straight
Take back for producing, and realize that system stably reaching standard is run, be particularly strict in the ground of national grade one discharge standard to Effluent criteria
Area.Not only effluent quality is good for the system, and with it is stable, operating cost is low, the advantage of strong shock resistance.
