Cyanide containing wastewater treatment is oxidation cyanide breaking high cyanide wastewater treatm

Cyanide-containing wastewater treatment, cyanide-breaking wastewater treatment method? Chemical, electroplating, circuit board and other industries generally use cyanide-containing as intermediate raw materials, although the effect is better, but cyanide residue is a more difficult problem to solve, in addition to the use of sodium hypochlorite to solve, there are also a few factories using carbamine and other removal of cyanide, which leads to another problem, when using these special agents for treatment, it is necessary to adjust the cyanide-containing wastewater to acidic conditions, as we all know, under acidic conditions, cyanide is easy to become hydrocyanic acid and emit out, resulting in highly toxic surrounding gas. Based on this, Suzhou Yiqing Environmental Protection Technology Co., Ltd. has developed an oxidation cyanide breaking equipment, which occupies a small area and has low operating costs.

The treatment of cyanide-containing wastewater or nitrile-containing wastewater has always attracted much attention, Suzhou Yiqing Environmental Protection Technology has developed a new type of oxidation equipment, which only needs to consume hydrogen peroxide to greatly reduce the content of cyanide or organic nitrile, H2O2 can make free cyanide-containing and its metal complexes (but not iron-containing cyanide) oxidized into cyanate, copper, nickel and zinc and other metals in the form of metal cyanide complexes, once the cyanide is oxidized and removed, they will generate hydroxide precipitation. Those excess hydrogen peroxide can also quickly decompose into water and oxygen. The equipment can not only remove cyanide, but also break the metal complex bond to achieve the dual effect of breaking the cyanide and breaking the cyanide.

In addition, the treatment of cyanide-containing wastewater or nitrile-containing wastewater has been attracting much attention, and the existing treatment process in addition to adding chemicals, the commonly used processes also have electrocatalysis and Fenton processes, the treatment effect of these two processes has great limitations than the pharmaceutical method, and a large number of hazardous wastes will be produced simultaneously, and the disposal of these solid wastes is another problem that is difficult to solve. Suzhou Yiqing Environmental Protection Technology Co., Ltd. has developed another kind of oxidation and cyanide breaking equipment for the current market demand, the equipment only needs to consume hydrogen peroxide to greatly reduce the content of cyanide or organic nitrile, can completely degrade organic nitrile, cyanide from about 20,000 to 1ppm below, operating costs below 20 yuan tons, while not producing secondary pollution, no waste gas, no precipitation, no increase in salinity, at the same time can improve the B c of the effluent, the effluent directly into the biochemical process.
