Description
Technical field
The utility model belongs to technical field of waste water processing, and in particular to a kind of mark that carries is to the industry for being better than IV class water of earth's surface
Level-one A standard waters are carried mark to better than IV class water of earth's surface or III class water quality standard by wastewater treatment equipment.
Background technology
As China's water pollution problems increasingly highlights, the raising of Industrial Wastewater Treatment discharge standard has been trend of the times.From
The requirement that current quality of water environment improves sees, treated that water outlet is often discharged into urban river for many industrial treatment factories, becomes
The water body in river.Existing industrial effluent treatment plant of China is discharged after advanced treating, and discharge standard refers to more《Integrated wastewater
Discharge standard》Level-one A in (GB 8978-1996).However for level-one A standards, water quality just corresponds to bad the V of surface water
Class water, and be used water difficult to degradate.This water quality is discharged into the water body environment there are few self-purification capacity, and water body is caused not have not only
It to reparation, is polluted instead, the phenomenon that ' the more controlling the more dirty ' then occurs.Water pollution increasingly sharpens, an urgent demand difficulty drop
The water outlet of solution industrial effluent treatment plant carries mark to IV class of earth's surface or III class standard by level-one emission standard A.At present, Beijing, Zhejiang etc.
More areas begin preparing for pilot work, to wastewater treatment plant effluent CODCr、BOD5, ammonia nitrogen, total nitrogen, TP, DO etc. requirement higher.
1 Effluent criteria level-one A of table carries mark to IV class of earth's surface or III class standard water quality contrast table
At present, including the nitrogenous organic industry difficult to degrade such as coking, chemical industry, petrochemical industry, printing and dyeing, leather, papermaking, medicine, pesticide
Waste water, though ammonia nitrogen and most of organic matter can be effectively removed, still contains certain dense after advanced treating in waste water
Hardly degraded organic substance, ammonia nitrogen, total nitrogen of degree etc., although up to standard to level-one A standards, this wastewater biodegradability after advanced treating
It is very poor, it needs that level-one A waste water could be carried to mark to IV class of earth's surface or III class water standard, intractability by further precision processing
It is higher；Traditional essence denitrogenation exists frequently with denitrification and denitrogenation biological filter：Denitrification bio-filter after additional carbon goes out
Water CODCrInfluent COD can be comparedCrGao Yue -10~15mg/L is discharged CODCrIt is unstable；Rarely have technique that can meet better than earth's surface at present
The mark transformation that carries of IV class or III class high-quality industrial wastewater requires.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of mark that carries to the industrial wastewater for being better than IV class water quality of earth's surface
Processing unit, it is characterised in that：It is aerobic except carbon/nitrification biofilter, second level anoxic by ozone precision processing pond, the first order
Denitrification bio-filter, the third level are aerobic except carbon biofilter, clear water reserviors, sterilization pool are sequentially connected in series；Second level anoxic is anti-
Nitrify biofilter setting additional carbon dosing system；Through the device, treated that effluent quality can reach IV class of earth's surface or III class
Water standard.
The first order is aerobic except carbon/nitrification biofilter and the third level are aerobic except carbon biofilter is preferably upward flow
It is aerobic except carbon/nitrification biofilter or it is interior cycle it is aerobic remove carbon/nitrification biofilter.
The second level anoxic denitrification biofilter is preferably upward flow anoxic denitrification biofilter；Described is outer
It is preferably methanol, sodium acetate to add carbon source；The additional denitrifying carbon source dosage is slightly excessive.
The beneficial effects of the utility model：Ozone precision processing effectively increases the biodegradability of waste water, and eliminating part has
Machine object；The first order removes the sufficiently effective water outlet dissolved oxygen that ozone precision processing is utilized in carbon/nitrification biofilter, degrades waste water
In whole ammonia nitrogens and biodegradability organic matter；It is thrown under the conditions of the carbon source added outside second level anoxic denitrification biofilter
The carbon source added is slightly excessive, to ensure to remove all total nitrogens；The third level carries out carburizing reagent except carbon biofilter, can consume
The residual COD of second level anoxic denitrification biofilter additional carbon ensures the stabilization of water outlet COD；The utility model can be true
It protects level-one A industrial wastewaters and carries mark to IV class of earth's surface earth's surface or III class high-quality water quality standard.
