Abstract
The invention relates to a remover for high-concentration hardly degraded organic pollutants, which is prepared by mixing hydrogen peroxide with the molecular formula of H2O2, ferrous sulfate with the molecular formula of FeSO4 and purified water, wherein the weight part ratio of the hydrogen peroxide to the ferrous sulfate is between 2.5:1 and 3:1. The invention has the benefits of lower cost and wider temperature and pH ranges and can reach higher COD (Chemical Oxygen Demand) removing rate; and the invention has the characteristics of quick degradation and favorable mineralizing effect and can realize that the biodegradability of organic matters in landfill leachate can be effectively improved in the pretreatment period.
Description
Technical field
The present invention relates to a kind of pollutant removal agent, relate in particular to the agent of a kind of high-concentration hardly-degradable organic pollutant removal.
Background technology
Raising along with living standards of the people, the solid waste of discharging is increasing, produce total amount to National urban rubbish in 2010 and be about 4,400 ten thousand tons, in the refuse treatment process, can produce the percolate of some amount, if percolate is not carried out effectively innoxious appropriate disposal, will cause serious secondary pollutions such as groundwater pollution, odor pollution.And percolate pollutant concentration content height is a kind of complicated component and is difficult to biodegradable waste water and environment is had bigger harm; Because the composition of percolate depends on the accumulation time limit and the accumulation mode of refuse landfill solid waste, wherein the variation of organism, inorganics and heavy metal composition is bigger and unstable, and therefore, the percolate of high density is more difficult.At present, percolate is through COD and NH3-N still the exceed standard discharging of biological treatment in the rear filtrate, through monitoring analysis, find to contain in the waste water 10%～15% and be difficult to biochemistry or can not biochemical organism, waste water disposal facility is imported and exported water sample analysis to be found, be partly with the cyclic organic compound in the sewage, mainly contain naphthenic hydrocarbon, acids, carboxylic-acid, phenol etc., its structure, composition and content do not change before and after sewage disposal basically, and the simple biochemical processing process flow process that adopts of this explanation has very big deficiency.Problem at original treatment process existence, people have increased the physico-chemical process treatment process, with the ring-type organism macromole chain rupture cracking that is difficult to biochemical degradation in the sewage become can be biochemical small-molecule substance, wherein the materialization removal method of COD mainly contains absorption, membrane sepn, coagulating sedimentation, chemical oxidation, reverse osmosis etc., but there is the expense height in conventional materialization removal method, is subject to the shortcomings such as influence of factors such as pH and water temperature, in addition, very easily cause secondary pollution.
Summary of the invention
At above defective, the invention provides that a kind of cost is lower, temperature and the pH scope with broad, the high-concentration hardly-degradable organic pollutant removal agent that can reach higher COD clearance, thereby can improve degradation speed and optimize the mineralising effect.
For achieving the above object, the present invention is by the following technical solutions:
The agent of a kind of high-concentration hardly-degradable organic pollutant removal comprises that by molecular formula be H
2O
2Hydrogen peroxide, molecular formula be FeSO
4Ferrous sulfate and pure water be mixed and made into, the ratio of the proportioning weight part of hydrogen peroxide wherein and ferrous sulfate is between 2.5: 1 to 3: 1 in the scope; The proportioning weight part of described hydrogen peroxide, ferrous sulfate and pure water respectively is 25%, 10%, 65%; The proportioning weight part of described hydrogen peroxide, ferrous sulfate and pure water can respectively be 30%, 10%, 60%.
The beneficial effect of high-concentration hardly-degradable organic pollutant removal of the present invention agent is: temperature and the pH scope that cost is lower, have broad, can reach higher COD clearance; Have degradation speed and reach the mineralising good effectiveness soon; Can be implemented in effective biodegradability that improves hardly degraded organic substance in the percolate of pre-treatment phase.
