Problems solved by technology
At the same time, the ammonia and phenolic gases in the sewage are easy to volatilize into the atmosphere and reduce the air quality in the lives of the surrounding residents.
Although there are many water treatment technologies at present, the treatment effect on organic macromolecules in semi-coke wastewater is not ideal, and there are also disadvantages of high cost. It is necessary to propose a more effective semi-coke treatment device

The invention discloses a device for treating semi coke waste water, and belongs to the technical field of wastewater treatment in the process of preparing semi coke through low-temperature carbonization of coal. The device comprises a steam stripping chamber, a condenser and a condensing box which are sequentially connected through pipelines; a steam pipe and a waste water inlet pipe are arranged on the side wall at one side of the steam stripping chamber, a purifying chamber is formed in the bottom of the side wall at the other side, and a molecular sieve is arranged on an connector of the purifying chamber and the steam stripping chamber; a cold pressure gauge is arranged at the top of the steam stripping chamber, splitter plates for distributing waste water are arranged in the steam stripping chamber and comprise a first splitter plate, a second splitter plate, a third splitter plate and a fourth splitter plate, and the four splitter plates are arranged on the inner walls of the steam stripping chamber in a pairwise staggered mode. The device is simple in structure, convenient to use, environmentally friendly, capable of effectively treating phenols, ammonia nitrogen and other substances in the semi coke waste water and low in cost and saves energy.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment in the process of preparing semi-coke by low-temperature dry distillation of coal, and relates to a device for treating semi-coke wastewater. Background technique [0002] In the field of coal chemical industry in Shenfu, Yulin, Shaanxi, the basis of coal utilization technology is to prepare semi-coke by low-temperature dry distillation of coal and condense the discharged raw coal gas to produce coal tar. Coke quenching wastewater and condensed coal tar wastewater will be produced during the production process. These wastewaters contain ammonia nitrogen and phenolic substances. If these wastewaters are discharged into rivers and lakes, they will seriously pollute the water environment and soil environment. At the same time, the ammonia and phenolic gases in the sewage are easy to volatilize into the atmosphere and reduce the air quality in the lives of the surrounding residents. Alth...
