Abstract

The invention discloses a phenol-ammonia-semi-coke wastewater treatment device and a treatment method. The device comprises an oil separator, a plurality of extraction towers, a deacidification tower,a water tower, a deamination tower, an extraction agent circulating tank and a phenol tower. Organic matters and impurities such as oil, dust, phenol and the like in the phenol-ammonia raw material wastewater are removed by adopting an oil remover and an extraction oil removal method, so that the problems of device and equipment blockage, unqualified recovered product indexes, substandard effluent and the like in the traditional semi-coke phenol-ammonia wastewater treatment process are solved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a phenol ammonia blue carbon wastewater treatment device and a treatment method. Background technique [0002] China's resources are characterized by "rich coal, lack of oil and little gas". Coal is the main energy consumption in China, and low-rank coal reserves account for more than 55% of the country's proven coal reserves. An important measure for clean and efficient utilization and to ensure national energy security is to use coal as raw material and use thermal decomposition to dry distillation to produce clean fuels and basic chemical raw materials. ) conditions, during the production of (semi-coke) blue carbon clean fuel and coal gasification process, a kind of refractory, high CODVS industrial wastewater is produced, namely phenol ammonia blue carbon wastewater, which contains a large amount of refractory, highly toxic pollution substances, such as phenols,...
