Method and device for processing ceramic phenolic waste water

Abstract

The invention discloses a processing method for ceramic phenol wastewater and devices, which are characterized in that the method comprises steps of a, preliminarily processing the wastewater, charging the ceramic phenol wastewater in a cinder tank for adsorbing and filtering the wastewater, then charging in a drug-adding regulating reaction tank, injecting drug for reaction, regulating to enable the wastewater and medicaments to be uniformly mixed and deoiled, b, sequentially delivering the wastewater preliminarily processed into an iron-carbon first order reaction tank and an iron-carbon second order reaction tank for performing aeration micro-electrolysis reaction, retaining for a while, simultaneously performing circulating reflux between the two reaction tanks, c, delivering the wastewater treated via reaction step of the process b into a biochemical pond for further dephenolization and COD pollutant removal and d, performing advanced treatment. The processing method for ceramic phenol wastewater and the devices have the advantages of safe and reliable process, simple operation, low cost, low operation cost, good and stable processing effect and the like, and have perfect popularization value.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically relates to a method and device for treating phenol-containing wastewater. Background technique [0002] With the improvement of my country's economic level, the ceramic industry is currently developing vigorously, but at the same time it also brings a large amount of wastewater that is difficult to treat. For example, Foshan City, the hometown of ceramics, produces more than 6,000 tons of sewage every day, which is harmful to the environment. Pollution is also getting worse. At present, the main energy used by ceramic enterprises is coal-to-gas conversion. Therefore, ceramic wastewater contains phenol-containing wastewater that is difficult to treat. Among them, the concentration of phenol is high, the toxicity is high, and the pollution to the environment is also particularly large. Therefore, it is imminent to treat ceramic phenol-containing wastewater. . [...

Problems solved by technology

In the 1980s, a special treatment of organic wastewater was developed by using water in a supercritical state. Due to certain conditions, these methods may require on-site preparation of flocculants, or due to the influence of pH value and temperature. Therefore, it is difficult to stably treat ceramic phenolic wastewater. In addition, it is also affected by cost and equipment, which limits their widespread use in China.
