Embodiment 1

[0040] A specific embodiment of the present invention discloses a method for reducing the amount of phenol cyanide wastewater, such as figure 1 As shown, the source of phenol cyanide wastewater includes ammonium sulfate acid gas condensate, gas condensate, accident pool and defoaming water of phenol cyanide wastewater treatment station.

[0041] The method for reducing phenol cyanide wastewater includes reduction treatment of ammonium sulfate acid gas condensate water, reduction treatment of gas condensate water, reduction treatment of accident pools and reduction treatment of defoaming water in a phenol cyanide wastewater treatment station.

[0042] Each reduction treatment in the reduction method of phenol cyanide wastewater is described in detail respectively below.

[0043] Firstly, the ammonium sulfate acid gas condensate reduction treatment is introduced. The pollutants in the ammonium sulfate acid gas condensate water are mainly ammonia nitrogen.

[0044] The pickling ...

Abstract

The invention relates to a method for reducing the amount of phenol-cyanide wastewater, which belongs to the technical field of phenol-cyanide wastewater and solves the problem that there is currently no related technology for reducing the generation of wastewater from the source of phenol-cyanide wastewater, and the waste water produced in each link of the coking process is mixed with many types of pollutants. Handle difficult and high-volume problems. The reduction methods of phenol cyanide wastewater include the reduction treatment of ammonium sulfate acid gas condensate water, the reduction treatment of gas condensate water, the reduction treatment of defoaming water in the phenol cyanide wastewater treatment station and the reduction treatment of accident pools. The invention realizes reducing the production amount of phenol cyanide wastewater from the source.

Description

technical field [0001] The invention relates to the technical field of phenol cyanide wastewater, in particular to a method for reducing the amount of phenol cyanide wastewater. Background technique [0002] The toxic and harmful wastewater containing phenol, cyanide, oil and ammonia nitrogen produced during the coal coking process is called phenol-cyanide wastewater. Since this part of the wastewater contains various pollutants with high concentrations and multiple components, if it is discharged directly, it will pollute the environment. And the hazards are quite serious, so this part of the wastewater must be treated up to the standard before it can be discharged or recycled. [0003] With the country's economic development while ensuring the environment of "green mountains and green waters", pollution reduction has been determined as a binding indicator in the national environmental protection plan. Increase pollution reduction and environmental protection efforts, and ...
