Coking wastewater treatment agent and use method thereof

Abstract

The invention provides a coking wastewater treatment agent and a coking wastewater treatment process. The coking wastewater treatment agent comprises activity transforming agent, highly-efficient dispersant and coacervating agent. The coking wastewater treatment process comprises the steps of adding the activity transforming agent in the coking wastewater and well mixing the activity transforming agent and the coking wastewater, adding the highly-efficient dispersant to the solution and well mixing the high-efficient dispersant and the solution, adding the coacervating agent to the new solution and well mixing the coacervating agent with the new solution, and standing the solution until the solution is layered with light oil at the upper layer, treated water in the middle layer and solid precipitate at the lower layer. The coking wastewater treatment agent has unique effect on the coking sewage of high-concentration petroleum, suspended substance and COD in the coking wastewater, and the coking wastewater treatment agent is less affected by temperature. The coking wastewater treatment process is stable and reliable and convenient to manage, ensures the stable running of a sewage treatment plant and the discharge of the sewage after reaching standard, can treat the coking wastewater through slightly renovating original equipment and reduces the coking wastewater treatment cost.

Description

technical field [0001] The invention relates to an industrial wastewater treatment agent and a production process, in particular to a coking wastewater treatment agent and a use method. Background technique [0002] Coking wastewater is high-concentration organic wastewater produced in the process of coal coke, gas purification and coking product recovery. Its composition is complex, containing a large amount of organic pollutants such as phenols, biphenyl, pyridine, indole and quinoline, as well as toxic and harmful substances such as cyanide, inorganic fluoride ions and ammonia nitrogen. The pollutants have high chroma and are relatively difficult to biodegrade. High concentration organic industrial wastewater. Discharge that does not meet the standards will cause serious pollution to the environment and directly threaten human health. For this reason, the treatment of coking wastewater has always been a major problem in the field of wastewater treatment at home and abro...

AI Technical Summary

Problems solved by technology

In recent years, the method of industrial sewage chemical dosing treatment has been gradually improved. Due to its scientific principle and simple operation, it occupies a certain proportion of sewage treatment in large and medium-sized industrial enterprises. Coking factories generally use polyferric sulfate, but it has no effect on organic matter. The removal of

And the treatment of coking wastewater requires a lot of special equipment, which occupies a large area and costs a lot.
