[0002] Coal chemical coking is an important component in coal chemical field, and its core is to convert coal into coke, coke oven gas, coal tar and other products by high-temperature dry distillation. Coal chemical coking wastewater is a kind of industrial wastewater with complex composition and high pollutant concentration, containing various organic matter, ammonia nitrogen, phenol, cyanide and other harmful substances, which has great harm to the environment and ecological system. Therefore, after processing, the generated wastewater needs to be harmlessly treated to avoid direct discharge.
[0003] In order to neutralize the acidity of coal chemical coking wastewater, it is generally necessary to mix it with alkaline water before harmless treatment. The existing mixing equipment generally mixes and stirs wastewater and alkaline water directly. When the amount of wastewater to be treated is large, this direct mixing method will cause uneven contact between the two liquids, which will affect the neutralization effect.
[0004] Therefore, the skilled in the art proposes a coal chemical coking wastewater treatment device to solve the problem raised in the background art.
