The concrete steps that the waste water produced in cold-rolling process carries out advanced treatment through the utility model are as follows:
1) by cooling, neutralization reaction, coagulation, air supporting, roll waste water after inclined-plate clarifying basin process after biochemistry, more medium filter is entered by the first transfer lime, add appropriate flocculation agent PAC by flocculation agent chemicals dosing plant before entering more medium filter, in more medium filter, cold rolling wastewater removes SS, colloid and part COD in water through absorption, sedimentation, the mechanical picker effect of grading.
2) waste water of more medium filter process flows into ozone contact reaction pond through the second transfer lime, under the combined action of ozone, catalyzer, utilize the strong oxidizing property of ozone by inorganization for biochemical substances part difficult in cold rolling wastewater or be degraded to can biochemical substances, larger molecular organics is decomposed into small organic molecule, significantly improve the B/C ratio of waste water, strengthen rear class biological activated carbon filter to organic removal ability, thus reach the object effectively removing COD in waste water.
3) ozone contact reaction pond processed the 3rd transfer lime and entered intermediate pool, carried out buffer memory, and made ozone residual in waste water carry out self-decomposition, to eliminate the impact on rear class biochemical system.
4) water outlet of intermediate pool by the middle water pump lifting of the 4th transfer lime to biological activated carbon filter, the organism of biological activated carbon filter first in planar water, then degrade to the organism of absorption again, thus remove the COD in water, last water outlet enters outlet sump.
5) backwash is replaced to the air-water of more medium filter, ozone contact reaction tower and biological activated carbon filter; The water that backwash water pump extracts pond is washed more medium filter, ozone contact reaction tower and biological activated carbon filter; Backwash water enters biological activated carbon filter through backwash water house steward and the first backwash arm, discharges through the first backwash delivery pipe; Backwash water enters biological activated carbon filter through backwash water house steward and the second backwash arm, discharges through the second backwash delivery pipe; Backwash water enters biological activated carbon filter through backwash water house steward and the 3rd backwash arm, discharges through the 3rd backwash delivery pipe; Blower fan by inlet manifold be more medium filter, ozone contact reaction tower and biological activated carbon filter provide pressurized air, wherein pressurized air enters more medium filter by the first inlet pipe, enter biological activated carbon filter by the second inlet pipe, ozonizer enters ozone contact reaction tower by ozone inlet manifold.Water outlet is reused, arrives the effect of energy-saving and emission-reduction.
The beneficial effect of cold rolling wastewater system of the present utility model is:
Native system equipment is simple, reliable, ideal treatment effect.After this system process, the CODcr of water outlet is less than 30mg/L, and SS is less than 10mg/L, reaches emission request.Can be out of the water reuse simultaneously, and effluent quality can ensure the steady operation of follow-up reclaiming system, reduces the load of follow-up equipment.
