Abstract

The invention discloses a treatment process and equipment for organic matter pyrolysis wastewater, and relates to the related technical field of pyrolysis wastewater treatment. The method comprises the following steps: A, flocculating settling; B, filter pressing; C, catalytic oxidation of ozone micro-nano bubbles; D, MBBR; and E, RO / AC. A filter pressing device in the step B comprises an air box,the bottom of the air box is fixedly connected with a plurality of first sealing gaskets, the inner surfaces of the first sealing gaskets are each fixedly connected with an air guide pipeline, the lower portion of the outer surface of each air guide pipeline is fixedly connected with a second sealing gasket, and the outer surface of each second sealing gasket is fixedly connected with a cover plate. According to the invention, the decomposition speed of ozone micro-nano bubbles to organic pollutants is increased by more than 30 times or more by using a special catalyst; B / C of pyrolysis wateris increased from 0.02 to 0.35 or above, so that the pyrolysis water has biodegradability, inorganic salt in the wastewater is removed through RO, organic pollutants which are finally difficult to decompose are removed through activated carbon, and the pyrolysis wastewater is recycled.

Description

technical field [0001] The invention relates to the related technical field of pyrolysis wastewater treatment, in particular to a treatment process for organic matter pyrolysis wastewater. Background technique [0002] During the air-isolated pyrolysis process of RDF, coal, bamboo and wood organic matter, with the difference of pyrolysis temperature, the ratio and characteristics of the three products of gas, liquid and solid are different. Pyrolysis gas (combustible gas) is usually consumed as fuel in the pyrolysis process, and the excess part is output in the form of gas; the solid product of pyrolysis can be coke, carbon powder, charcoal depending on the raw material; and the content of organic matter and pyrolyzed water in the liquid In addition to changing with the moisture content of raw materials, organic liquid is also called pyrolysis oil, which is often used in the refining of chemical raw materials and the production of fuel oil. Pyrolysis water belongs to high-c...
