Description
technical field [0001] The invention belongs to the field of sewage treatment, in particular to a waste water treatment device for the catering industry. Background technique [0002] Catering industry wastewater refers to the untreated wastewater discharged by the catering industry. Its characteristic is that the wastewater contains a large number of colloidal particles and suspended solids, the main components of which are animal and vegetable oils, inorganic salts, surfactants and proteins. According to the statistics of relevant departments, the untreated wastewater discharged by the catering industry in my country is nearly 100 million tons every year, and there is a growing trend. General catering industry wastewater discharge accounts for about 3% of urban domestic sewage discharge, but its BOD5 and CODCr content accounts for 1 / 3 of the total load. According to the detection of catering industry sewage pollution indicators in several major domestic cities The result...
