Problems solved by technology

The biochemical treatment method has unstable treatment effect and high cost; although the separate incineration method has a good treatment effect, the treatment cost is high; the coal-water slurry preparation system of the coal-water slurry treatment method has a large investment, and many manufacturers do not have this system, so it is difficult implement

Abstract

The invention provides a treatment method of phenol-cyanogen wastewater generated by a coal gas producer. The method comprises the treatment work procedures of filtration, CO2 pressurized iron carbon micro-electrolysis, precipitation, hydrolytic acidification, aerobic treatment, biological filtration tower treatment and the like; the treated wastewater can be stably discharged in a standard reaching manner.

Description

technical field [0001] The invention relates to a treatment method for phenol cyanide wastewater produced by a gas generator. Background technique [0002] Coal gas is a kind of fuel widely used in production and life. It is produced from coal through a series of chemical reactions in a gas generator. In the process of preparing cold gas, phenol-cyanide wastewater (wastewater containing phenol and cyanide) will inevitably be produced. If the wastewater is directly discharged into the environment, it will cause serious pollution to the environment. At present, the treatment methods of phenol cyanide wastewater mainly include biochemical treatment method, separate incineration method, coal water slurry treatment method and raw material treatment method mixed into drying tower. The biochemical treatment method has unstable treatment effect and high cost; although the separate incineration method has a good treatment effect, the treatment cost is high; the coal-water slurry pre...
