Description
Technical field
The invention belongs to technology for treating industrial waste water, relate in particular to a kind of advanced treatment of industrial waste water recycling system.
Background technology
At present, in large-scale chemical plant, all will produce a large amount of trade effluents every day, even its COD(chemical oxygen demand (COD) after processing by biological method or physical method) and turbidity also only can reach secondary discharge standard (COD is generally 90mg/L); The cooling tower of factory needs again to add a large amount of water coolants simultaneously, but directly adds the waste water after processing can cause the water coolant bacteria content sharply to raise, and affects cooling performance and service life of equipment, also can bring extra maintenance, cleaning up cost.
Summary of the invention
The object of the present invention is to provide a kind of advanced treatment of industrial waste water recycling system, it can make the COD of waste water and turbidity reach middle water quality standard, then introduce used for cooling tower in the refrigeration cycle use of (once adding and moisturizing), make waste water realize recycle and zero release, to solve the problems referred to above that in prior art, reusing industrial effluent exists.
For reaching this purpose, the present invention by the following technical solutions:
A kind of advanced treatment of industrial waste water recycling system, it comprises settling tank, the coarse filtration device, the deep oxidation device, fine filtering apparatus and circulatory pool, wherein, described settling tank connects the coarse filtration device by pipeline, described coarse filtration device connects the deep oxidation device by pipeline, described deep oxidation device connects fine filtering apparatus by pipeline, described fine filtering apparatus connects circulatory pool by pipeline, described circulatory pool connects the cooling tower of coarse filtration device and fine filtering apparatus by circulation line, described deep oxidation device comprises ozone pretreatment unit and the activated carbon combined treatment unit of Chou Yang ∕ connected successively by pipeline.
Especially, described settling tank adopts the inclined tube-type settling tank.
Especially, described coarse filtration device comprises the first coarse filter and the second coarse filter connected successively by pipeline.
Especially, described fine filtering apparatus comprises the first fine filter and the second fine filter connected successively by pipeline.
The trade effluent that process biological method and physical method were processed enters sewage works by settling tank by pollutant emission, from settling tank, waste water out enters suspended solid coarse filtration device filtered water, the waste water penetration depth oxidation unit of processing through the coarse filtration device, waste water first contacts the ozone pretreatment layer, by aerating apparatus, ozone is fully mixed with water, decompose and be difficult to the pollutent decomposed by common biological method for treating waste water, larger molecular organics is decomposed into to small organic molecule, assist and fill into air simultaneously, enter the activated carbon combined treatment unit of Chou Yang ∕, the activated carbon combined treatment unit of described Chou Yang ∕ adsorbs small organic molecule, generate a kind of newborn OH simultaneously
-there is extremely strong oxidation activity, through fine filtering apparatus, filter afterwards, finally, the waste water of processing becomes middle water, and as the reuse of finished product water, described tube settler precipitates the macrobead pollutent in waste water, and according to action of gravity, pollutant emission being entered to sewage works, described fine filtering apparatus is removed mist of oil, the solid particulate in water.
Beneficial effect of the present invention is, after compared with prior art described advanced treatment of industrial waste water recycling system is carried out coarse filtration, deep oxidation and essence filtration successively by trade effluent, to make trade effluent reach middle water quality standard.Waste water can all reclaim as cooling water replenishment, has not only saved the water resources of a large amount of preciousnesses, and makes waste water realize zero release, is conducive to environment protection.
