Background technology
Along with the development of China's science and technology in recent years, and to all kinds of production and the supervision of product and the reinforcement of inspecting force, emerge like the mushrooms after rain in all kinds of research and development type laboratory and detection type laboratory, cause that various laboratory waste water is anxious to be increased.Laboratory waste water mainly results from the process of various research and development experiment, inspection, and because of the special property of himself, such as quantity discharged is few, and discontinuity is strong, and the harm of high toxicity height, complicated component is changeable, causes the process of laboratory waste water very difficult.To be that many laboratory waste water are unprocessed be just directly discharged current reality, becomes serious water resource pollution source.
In the laboratory waste water of different operating character, the composition of contained pollutent is different, generally can be divided into inorganic wastewater and the large class of organic waste water two.Laboratory inorganic wastewater is mainly containing heavy metal, heavy metal complex, soda acid, prussiate, sulfide, halide-ions and other mineral ions etc.Laboratory organic waste water contains the materials such as conventional organic solvent, organic acid, ethers, polychlorobiphenyl, organo phosphorous compounds, petroleum-type, lipid, phenols, ketone, Comparatively speaking, organic waste water is higher than the toxicity of inorganic wastewater, pollution wider, and the harm brought is more serious.Chemistry of laboratory waste water, according to the difference of its concentration, can be divided into low concentration wastewater and high-concentration waste water again.Laboratory high-concentration waste water be mainly derived from label come off after not clear deliquescent agent, the liquid reagent (as organic solvent waste liquid etc.) lost efficacy, scientific research and the liquid state in testing test waste products or byproduct (sample analysis raffinate, liquid product and byproduct etc.), the washings etc. after hypertoxic drug study.Comprehensively above-mentioned two kinds of classification to laboratory waste water, obviously, the chemistry of laboratory waste water of high density, high toxicity (organic), especially difficult density of infection of decomposing organic composition is the highest, if very difficult imagination high density so, high toxicity laboratory waste water just discharge without thorough process the hazard rating produced environment.
The treatment process of existing laboratory waste water mainly comprises biological process and physico-chemical process.Biological process is the strong and laboratory that complicated component is changeable for high density, high toxicity, discontinuity
organicthe treatment effect of waste water is not good, and reason is the groundwork key element of biological process---and active sludge is easily dead by the pollution of toxic organic compound, is difficult to manipulation.And physico-chemical process, comprising the technology such as absorption, coagulation, membrane sepn, is after being reclaimed by the organic solvent in the organic waste water of laboratory etc., and recycling chemical process processes.Although the pollution that physico-chemical process reduces environment by the recovery to pharmaceutical chemicals, recycling, this method needs specific installation, and investment is large, complex process, and operating cost is high.The more important thing is, physico-chemical process is not suitable for the process of irretrievable high toxicity organic liquid waste.Therefore, this type of waste liquid generally carries out centralized burning process, and not only energy consumption is high, more has the potential secondary harm polluting air.
