Abstract

The invention relates to a phenol cyanide wastewater treatment system which comprises a water dividing device, a biochemical treatment device, an activated carbon adsorption device and a biological denitrification device. The water dividing device is respectively connected onto the biochemical treatment device and the biological denitrification device and selectively discharges wastewater to be processed into the biological treatment device or the biological denitrification device according to preset wastewater treatment standard. The biochemical treatment device is formed by an activated sludge treatment device or a biofilm treatment device and connected with the activated carbon adsorption device. Activated carbon used for further treating wastewater treated by the biochemical treatment device is arranged in the activated carbon adsorption device. Aerobic bacteria and anaerobic bacteria are arranged in the biological denitrification device. The phenol cyanide wastewater treatment system respectively adopts the biochemical treatment device, the activated carbon adsorption device and the biological denitrification device to treat phenol cyanide wastewater, is capable of adapting to phenol cyanide wastewater with various properties and discharged under different working conditions and achieves the aim of unite treatment of the wastewater.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a phenol cyanide wastewater treatment system. Background technique [0002] The wastewater containing phenol and cyanide mainly comes from the coking production of the coking plant, followed by the gas generation station and the blast furnace gas washing circulating water system. During coal dry distillation, the moisture in coal escapes together with the gas, and is discharged during the gas cooling and gas-liquid separation process. Another part of phenol cyanide wastewater comes from the separation water and sewage in the process of gas purification and chemical product processing. Under normal circumstances, the amount of wastewater generated in coking plants is about 0.51-0.82m per ton of coal 3 , the composition of the waste water is complex and the concentration is high. In addition to phenol and cyanide, there are ammonia and sulfide. Generally,...
