Abstract

The invention discloses a modular integration process method for kitchen waste filtrate and belongs to the technical field of water treatment. Wastewater is monitored by a water quality monitoring module, a computer controls a PLC self-control system to control the wastewater to enter a primary or secondary physico-chemical module alternatively, and the wastewater is treated by anaerobic and aerobic biochemical modules and a deep treatment module. The modular integration process method is applicable to miniaturized, rapid and dispersed treatment of high-salt, high-COD, high-colority and great-fluctuation kitchen waste filtrate; the process method has high integration, intelligence and modularization degree and facilitates transformation from a technology to integrated equipment and space is saved; the process is manure and reliable and can be used for treating oil, nitrogen and phosphorus simultaneously to stably meet the standard, and effluent can be recycled; the adopted microelectrolysis method and a Fenton reagent strengthening process integrates oxidoreduction, flocculation, adsorption, catalytic oxidation, electrolytic deposition, codeposition and the like, chain scission of macromolecular organic pollutants can be realized, and refractory organic matter can be further removed.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a modular integration process method of kitchen waste filtrate. Background technique [0002] Food waste, commonly known as swill, is food processing waste and food residues generated in the daily life of residents, the catering industry, and the production and operation of unit canteens. The leftovers produced by restaurants, canteens and other catering industries have the characteristics of large production volume, multiple sources, and wide distribution. However, the amount of discarded leftovers produced by residents' daily cooking is not as huge as catering waste. Generally speaking, food waste is rich in organic matter and water, and is perishable. Its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins. [0003] At present, many cities ...
