Description

Device for treating coal chemical wastewater by anaerobic co-metabolism

Technical Field

The utility model relates to the technical field of chemical industry, in particular to a device for anaerobic co-metabolism treatment of coal chemical wastewater.

Background

The coal chemical industry wastewater becomes one of the currently recognized industrial wastewater difficult to treat at home and abroad due to the complex composition, high content of toxic and harmful pollutants difficult to degrade and the like. The organic pollutants in the wastewater mainly comprise phenolic compounds, polycyclic aromatic compounds, heterocyclic compounds, long-chain aliphatic hydrocarbons and the like, and the inorganic pollutants mainly comprise fixed ammonia, free ammonia, sulfur, cyanide and the like. At present, the treatment process of the coal chemical industry wastewater is mainly formed by combining physicochemical and biochemical processes. The initial phenolic compound and ammonia nitrogen concentration of the coal chemical industry wastewater can respectively reach more than 2000mg/L and 5000mg/L, and the biochemical treatment can not be directly carried out. Therefore, the treatment of the coal chemical industry wastewater needs physicochemical pretreatment. The common pretreatment methods include phenol extraction, ammonia distillation, oil removal, air flotation, coagulation and other measures.

In order to solve the problems, new methods for treating the coal chemical industry wastewater, such as an anaerobic biological process, an advanced oxidation technology, a coagulation process, an adsorption process and the like, are provided. Anaerobic biological treatment waste water equipment's water inlet is mostly all in the lower part of equipment, mud is inside on the equipment, move down, and then increase reaction time and efficiency, however, mud easily blocks up the inlet tube, it is probably to appear the phenomenon that the inlet tube is blockked up occasionally to lead to the waste water to carry, lead to the efficiency decline of waste water transport, purify, the efficiency of processing also descends, in addition, the organic gas when current sewage treatment equipment is not convenient for collect waste water biochemical reaction, the waste of resource has been caused, the quality of water of partial equipment play water is not good, comparatively muddy, partial high-quality mud is not convenient for recycle once more, make activated sludge's utilization ratio descend.
