Description
Technical field
The utility model relates to a kind of device of administering water containing chlorine organism, nitrate and heavy metal contaminants.
Background technology
Produce and life process in all contaminations that discharges enter environment by all means, severe contamination atmosphere, soil, underground water and surface water system, serious threat human beings'health and is lived.Chlorinated organics, nitrate and heavy metal etc. are ubiquitous priority pollutants in the underground water, and these pollutents all are to mix to be present in polluted-water or the soil usually.
Quite a few is listed in the environment priority pollutants in the chlorinated organics, especially persistence organic pollutant, as DDT, phenyl-hexachloride, PCBs, multi-chlorophenol, vinylchlorid (VC) etc., these materials have very strong resistivity for the biological metabolism under the natural condition, photodegradation, decomposition etc., in case enter environment, be difficult to be decomposed, particularly enter in the surrounding mediums such as soil, underground water and bed mud and retain several years even many decades or longer time; In addition on the earth annual amount of nitrogen fixation also considerably beyond the nitrogen amount that discharges by denitrification, thereby cause the long-term accumulation of nitrate nitrogen in soil and underground water, NO
3 -Be reduced to NO after entering human body
2 -, NO
2 -Carcinogenesis is arranged or cause infant's methemoglobinemia.Heavy metal be different from other hazardous contaminant, they can not biological degradation, and can accumulate in vivo, thereby causes various diseases, threatens human health.
All there is multiple treatment process to be removed for different pollutents, but all is mostly, adopt certain treatment process under given conditions at a certain pollutent.As, the treatment process that is usually used in the azotate pollution water body has: ion exchange method, reverse osmosis method, biological process etc.But contaminated water body can not be by only being polluted by a kind of pollutent, usually all contain multiple pollutent, common especially pollutent such as chlorinated organics, nitrate, heavy metal etc. are applicable to that the method (as ion exchange method, reverse osmosis method, biological process) of treatment of nitric acid salt pollution water body but can not effectively be removed chlorinated organics.Therefore developing a kind of treatment technology that can remove multiple pollutent cheap, fast and efficiently synchronously has very important significance.
Summary of the invention
The purpose of this utility model provides a kind of device of administering water containing chlorine organism, nitrate and heavy metal contaminants.
It is connected with hopper, first flow control valve, pump, second flowrate control valve, column type reactor in turn, set on the column type reactor thief hole, middle thief hole, on thief hole, be provided with water outlet in the column type reactor upper end.
The utility model has the advantages that:
1) technical process is short, operational efficiency is high.The current that contain pollutent are promptly finished purification through column type reactor, and the reaction times only is 0.5-12 hour.
2) energy consumption low, applied widely, do not produce secondary pollution.Only need to squeeze into column type reactor and get final product, need not to heat, steps such as the adjusting of acid, interpolation medicament with the water that pump will contain pollutent.
3) reaction unit of the present utility model can move at normal temperatures and pressures, and Pollutant levels are not had special requirement yet, and is applied widely; Main charges are the discarded iron filings of machine works, turn waste into wealth, and are with low cost.
