Description
Technical field
The utility model relates to field of Environment Protection.Be specifically related to a kind of advanced oxidation Treatment of Wastewater in Coking bio-chemical effluent reclaiming system.
Background technology
The high concentrated organic wastewater that coking chemical waste water is coal coke, produce in gas purification and coke chemicals removal process.Coking chemical waste water mainly comprises the sewage that the Coal-gas Washing Water Using of the primary cooling stage gas condensed water of coal gas, gas end-cooling water, Coal-gas Washing Water Using and gas generating station, refining benzene Separation of Water, gas holder waste water, coke oven water seal water and other occasion produce.Coking chemical waste water principal pollutant matter has: COD, BOD, prussiate, ammonia nitrogen, suspended substance, phenol and benzene compounds etc., waste component is many, and complicated components, concentration are high, toxicity is large, difficult degradation.Containing tens of kinds of inorganic and organic compound in waste water, wherein mineral compound mainly a large amount of ammonium salt, sulphur, sulfide, prussiates etc.; Organic compound, except phenol, also has the organic pollutants such as biphenyl, pyridine, indoles and quinoline.Pollutent colourity is high, belongs to the high-concentration organic industrial waste water compared with bio-refractory.COD, NH in coking chemical waste water
3the Pollutant levels such as-N and volatile phenol are high, and these pollutents can have high risks to the mankind, aquatic products and farm crop.
At present, coking chemical waste water generally will just may qualified discharge after pre-treatment, second-stage treatment and advanced treatment, but in industry, situation up to standard is not satisfactory.After emission standard improves in present country, qualified discharge more becomes Treatment of Coking Effluent a great problem up to standard, and coking wastewater deep treatment qualified discharge has become a difficult problem in the urgent need to address.
Utility model content
The purpose of this utility model is to provide a kind of improvement by system and reaches discharged wastewater met the national standard and the Waste Water Treatment that can realize whole Water circulation.
In order to achieve the above object, the utility model has following technical scheme:
A kind of advanced oxidation Treatment of Wastewater in Coking bio-chemical effluent reclaiming system of the present utility model, comprise the collecting tank, lift pump, line mixer, combination type photocatalysis oxidizer system and the coagulation air-float system that successively connect successively, described coagulation air-float system is discharged pond with biochemical system sludge sump or reuse respectively and is connected.
Further, described combination type photocatalysis oxidizer system comprises gas-liquid photocatalysis oxidation reaction apparatus and ultraviolet catalytic oxidation waste disposal plant, is connected between described gas-liquid photocatalysis oxidation reaction apparatus and ultraviolet catalytic oxidation waste disposal plant by a high pressure transforming valve.
Further, described gas-liquid photocatalysis oxidation reaction apparatus comprises a still air feeder, and the hollow fiber film thread be provided with in described still air feeder becomes cross-like to arrange.
Further, described ultraviolet catalytic oxidation waste disposal plant also comprises a gas-water mixer, and the front end of described gas-water mixer is provided with a dropping valve.
Owing to taking above technical scheme, the utility model has the advantage of:
Advanced oxidation system is adopted to process the water outlet of coking wastewater biochemical system, organic pollutant remaining after sufficient oxidation mineralising biochemistry, organic pollutant after oxidation mineralising is completely broken down, the suspended substance in waste water is removed and on a small quantity by the organism adsorbed, water outlet can reach plant area's recycle water standard again through coagulation air-float system; Waste water realizes qualified discharge after treatment, and most of water outlet can be back to use in the production technique of front end, has both solved the difficult problem of environmental protection being difficult to coking chemical waste water qualified discharge, can carry out production reuse again, and reduce the production cost of enterprise to product water.
By the utility model be water saving, wastewater utilization, energy-saving and emission-reduction open new approach.
Structure of the present utility model is simple, easy to install, operation steps is simple.

Embodiment
Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.
See Fig. 1, a kind of advanced oxidation Treatment of Wastewater in Coking bio-chemical effluent reclaiming system of the present utility model, comprise the collecting tank, lift pump, line mixer, combination type photocatalysis oxidizer system and the coagulation air-float system that successively connect successively, coagulation air-float system is discharged pond with biochemical system sludge sump or reuse respectively and is connected.Combination type photocatalysis oxidizer system comprises gas-liquid photocatalysis oxidation reaction apparatus and ultraviolet catalytic oxidation waste disposal plant, is connected between gas-liquid photocatalysis oxidation reaction apparatus and ultraviolet catalytic oxidation waste disposal plant by a high pressure transforming valve.Ultraviolet catalytic oxidation waste disposal plant also comprises a gas-water mixer, and the front end of gas-water mixer is provided with a dropping valve.
More excellent, can comprise a still air feeder in gas-liquid photocatalysis oxidation reaction apparatus, the hollow fiber film thread be provided with in still air feeder becomes cross-like to arrange, and cross-like is arranged can more large-area fully oxidized reaction.
Pass through test in place, find that conventional deep treatment method is not suitable for Treatment of Coking Effluent, and due to coking chemical waste water bio-chemical effluent, to contain a large amount of hardly degraded organic substances, volatile phenol and COD concentration high, after biochemical system process, has been difficult to be removed by additive method; The utility model adopts knockdown photocatalytic advanced oxidation device system.Site test results shows, adopt this combination type photocatalysis advanced oxidation apparatus can reach 75% to the clearance of the COD in waste water, the clearance of hardly degraded organic substance, volatile phenol is more than 95%.
Due to organic pollutant very high concentrations various in coking chemical waste water, intractability is very large, and the utility model carries out advanced treatment for the problem that biochemical system water outlet is not up to standard; First coking chemical waste water bio-chemical effluent is entered collecting tank, then squeeze into line mixer by lift pump, then enter into combination type photocatalysis advanced oxidation device system, by photocatalytic oxidation, the organic pollutant in bio-chemical effluent can be removed in a large number; Waste water after the process of combination type photocatalysis advanced oxidation device enters into coagulation air-float system, and effectively can remove the suspended substance more than more than 99% in waste water, a small amount of organism is by scum silica frost Adsorption.Former coking chemical waste water bio-chemical effluent COD content is at 150-300mg/L, and the water outlet Absorbable organic halogens after the process of this patent system is at below 80mg/L, and water outlet is as clear as crystal, by qualified discharge device stably reaching standard discharge or reuse in production technique.
