Abstract
The invention relates to a method for treating heavy metal polluted sewage through a chelating agent. The water chelating agent is added to the heavy metal polluted sewage, the adding amount ranges from 0.3 g/L to 1 g/L, then stirring is conducted for 10-20 min, and the sewage is filtered and separated after standing still for 1-3 hours; the chelating agent is prepared from, by weight, 1-terpene-8-farnesyl acetate, polyethylene glycol, polyoxyethylene glyceryl ether, 2-aminobutane, 4-(4-hydroxy-3-methoxyphenyl)-2-butanone, carboxymethyl cellulose, salicin, polyoxypropylene diol, polyoxyethylene styryl phenyl ether, dimeric fatty acid, 10-hydroxy-2-caproleic acid, sepiolite and the like. Multiple heavy metal ions can be treated at a time through the chelating agent, and the removal rate reaches 98% or above. Meanwhile, the use amount of the chelating agent is low, secondary pollution to water is low, the treatment method is simple, and treatment cost is low.
Description
Technical field
The present invention relates to a kind of method using sequestrant process heavy metal polluted waste water, belong to technical field of waste water processing.
Background technology
Heavy metal wastewater thereby refers to the waste water containing heavy metal of discharging in the Industrial processes such as mining and metallurgy, machinofacture, chemical industry, electronics and instrument.Heavy metal (as containing cadmium, nickel, mercury, zinc etc.) waste water is that environmental pollution is the most serious and endanger one of maximum trade effluent to the mankind.
At present except the method for middle heavy metal ion of anhydrating has ion reduction, coagulation, co-precipitation, membrane filtration, ion-exchange and absorption etc.But above-mentioned treatment process is when processing the polluted-water containing contents of many kinds of heavy metal ion, and treatment effect is not good, can not simultaneously by thorough for contents of many kinds of heavy metal ion process.In addition, if the concentration of the heavy metal ion in waste water is lower, then heavy metal ion is difficult to remove especially.
Therefore be necessary to provide a kind of sequestrant simultaneously can removing multiple low-concentration heavy metal ions in waste water, thus effectively solve the process problem of Compound Heavy Metals waste water.
Summary of the invention
