Description
Technical field
The present invention relates to a kind of mosquito-repellent incense pretreatment method for wastewater, utilize pyrethroid to issue the principle of unboiled water solution and photolysis in alkalescence and UV-irradiation condition, in the basic conditions uv irradiating is carried out to mosquito-repellent incense waste water, promote that agricultural chemicals decomposes, reduce mosquito-repellent incense wastewater toxicity.
Background technology
In the process of producing coiled mosquito-repellent incense, electric mosquito repellent liquid, anti-mosquito incense sheet, discarded former medicine can be produced, the waste water that liquor piping, equipment and container produce is infected with in cleaning, these waste water are as directly entered sewage works without pre-treatment, can impact sewage plant, easily cause discharge to exceed standard, pastille waste water enters in aquatic ecological environment, can have a huge impact aquatic animals and plants, as dead in fishes and shrimps etc.So need first to carry out pre-treatment before pastille waste water enters sewage plant, enter sewage plant again after most farm chemical ingredients of first degrading, reach the operation not affecting sewage plant, the object of wastewater treatment qualified discharge.
Physics, chemistry, biological process etc. are had at present to the treatment process of agricultural chemicals waste water.Physical mainly contains absorption method, sonication, irradiation method etc. at present, absorption method has the material of adsorptivity or biological adsorption mainly through some and carrys out fractionation by adsorption and go out agricultural chemicals, but the material adsorbed has become again danger wastes needs process in addition, and the cost of investment of sorbing material is also higher simultaneously; Namely supersonic method utilizes liquid to produce cavitation effect under ul-trasonic irradiation to carry out degrading pesticide, at present technical comparative maturity, and shortcoming is that investment is large, running cost is high; Irradiation method is the method utilizing ionizing rays decomposing pesticide, does not need to add chemical agent, noresidue, energy consumption are low, but facility investment large, have radiological hazard etc., less use.Chemical method comprises the methods such as oxygenolysis, hydrolysis, coagulation, and wherein oxygenolysis utilizes strong oxidizer to process agricultural chemicals waste water, and running cost is high; Hydrolysis is that agricultural chemicals is unstable and hydrolytic action occurs in alkaline aqueous solution, but effect is general; Coagulation adopts coagulating agent process pastille waste water, and one is that medicament expense is comparatively large, and two is to produce pastille mud, and mud also needs other disposal.Biological process mainly carrys out degrading pesticide by enzymatic reactions such as microorganism, degrading enzyme, engineering bacterias, on the one hand because agricultural chemicals inherently has bio-toxicity, add the high and difficult degradation of concentration, cause Biochemical Treatment poor, at present separation and purification obtained to pesticide degradable enzyme and carried out more deep physiological and biochemical research, but still can not produce on a large scale and practical application.
Summary of the invention
For the treatment process of existing agricultural chemicals waste water, the object of the present invention is to provide a kind of mosquito-repellent incense pretreatment method for wastewater, utilize pyrethroid to issue the principle of unboiled water solution and photolysis in alkalescence and UV-irradiation condition, in the basic conditions uv irradiating is carried out to mosquito-repellent incense waste water, promote that agricultural chemicals decomposes, reduce mosquito-repellent incense wastewater toxicity.
