The invention discloses a pretreatment deoiling device for coal chemical wastewater. The device comprises an oil separation tank, wherein a slag scraper is arranged at the bottom of an inner cavity ofthe oil separation tank, aeration pumps are arranged on one side of the slag scraper, and aeration pipes are arranged at the tops of the aeration pumps; a stainless steel isolation net is arranged atthe top of the inner cavity of the oil separation tank, an absorption area is arranged at the top of the stainless steel isolation net, and a plurality of porous spherical suspended filler is arranged in the absorption area; fixing plates are arranged at the top of the oil separation tank, a first drain pipe is arranged on the side wall of the oil separation tank, a stop valve is arranged on thefirst drain pipe, an inner wire connecting pipe is arranged at the end of the first drain pipe, and an absorption pipe is arranged at the bottom of the inner wire connecting pipe. The porous sphericalsuspension filler is matched with a filter material in the absorption pipe and a biological rotary table to perform microbe absorption, so that floating oil, dispersed oil and emulsified oil in oilywastewater can be well absorbed and filtered, and quality of the treated wastewater can meet requirements of subsequent biochemical and other treatment processes.
Description
Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a coal chemical wastewater pretreatment and degreasing device. Background technique [0002] Coal chemical wastewater mainly comes from the coal thermal processing and gas purification process and the refining process of coal chemical products. The wastewater is a high-concentration organic wastewater with extremely complex pollutant components and many refractory substances. It contains oils, phenols, and cyanogens. Various pollutants such as chemical compounds and sulfides. Among them, oil pollutants are also difficult to treat in the treatment of coal chemical wastewater. If the treatment is not good, it will affect the normal operation of the subsequent processing unit. Existing oil removal devices often use a single oil removal method for treatment, and the treatment effect is poor. [0003] Therefore, it is necessary to invent a coal chemical wastewater pretreatment and...
