Problems solved by technology

The dry storage temperature in coke production is about 1000°C, while the dry storage temperature in semi-coke production is low, so semi-coke wastewater contains a large number of pollutants that have not been oxidized by high temperature, and its concentration is about 10 times higher than that of coking wastewater, which can be biochemically extremely low sex
[0003] At present, the treatment of semi-coke wastewater usually uses an

Abstract

The invention relates to the technical field of semi-coke wastewater discharge treatment, and discloses zero-discharge treatment equipment and method for semi-coke wastewater. The equipment comprisesa pretreatment module, a first treatment module used for oil removal and dephenolization, a deamination module used for deamination, and a second treatment module connected with the deamination module. The method comprises the following steps: preprocessing; oil removal and dephenolization synchronous treatment: mixing wastewater with a polyaluminum chloride demulsifier provided by a demulsifier storage box through a mixer, then enabling obtained mixture to enter a circular tank body, then adding a complexing extraction agent into the circular tank body by an extraction agent feeding assembly,and meanwhile, driving the mixed liquid in the circular tank body to rotate by a rotating cylinder; deamination treatment; and dynamic electric flocculation treatment; According to the semi-coke wastewater treatment equipment provided by the invention, the wastewater treatment efficiency can be improved; and the treatment method provided by the invention can effectively ensure the treatment effect and reduce the treatment process.

Description

technical field [0001] The invention relates to the technical field of semi-coke wastewater discharge treatment, in particular to a zero-discharge treatment device and method for semi-coke wastewater. Background technique [0002] Semi-coke, also known as semi-coke, is a low-volatility solid carbonaceous product obtained by using long-flame coal, non-caking coal, weakly caking coal, etc. A special kind of waste water, the composition of the waste water is complex, mainly containing coal tar substances, including methanol, ethanol, formic acid, acetic acid, benzene, toluene, xylene, trimethylbenzene, phenolic substances, carp, green onion, pea, etc. Tar-like substances contain a large amount of ring-chain organic compounds, nitrogenous inorganic compounds and ammonia nitrogen. The dry storage temperature in coke production is about 1000°C, while the dry storage temperature in semi-coke production is low, so semi-coke wastewater contains a large number of pollutants that have...
