Background art:
in the comprehensive resource disposal technology of garbage, the fine classification and sorting of the garbage is the most critical step. And the refined RDF with low water content, low ash content, and metal and inorganic particles cannot be obtained without fine classification and sorting of garbage, and the yield and the quality of main pyrolysis products (pyrolysis oil and pyrolysis carbon) of the RDF are difficult to guarantee. The garbage is not finely classified and sorted, pure perishable organic matters without RDF, metals and inorganic particles cannot be obtained, perishable objects which account for nearly half of the weight of the garbage cannot be found out, a landfill site is still needed, and pollution discharge such as percolate, landfill gas and the like is continuously generated in the landfill process. And the garbage is not finely classified and sorted, so that the metals in the garbage cannot be completely sorted, and the garbage cannot be recycled to the maximum extent. There is no fine classification of garbage, and the obtained inorganic residue cannot be rendered harmless by the simplest method, and becomes a burden of garbage disposal and a solid pollution source.
in the fine classification and sorting process of the garbage, in order to realize the fine classification and sorting, the utilization of the moisture in the materials and the sorting process water must give high attention. On one hand, the garbage contains water and is not assisted by additional process water, so that the fine classification and sorting of the garbage are difficult to realize, and on the other hand, after the wet classification and sorting, the sorting process water becomes high-concentration organic wastewater, the quantity is large, the treatment cost is high, the economic benefit of the project is seriously applied, and even the project cannot run. Recycling is the only way to solve the problem.
When the process water is used for finely classifying and sorting garbage, putrefactive parts of perishable organic matters in the garbage, percolate, and soluble biomass organic matters such as cell water generated by breaking perishable organic matters in the processes of RDF extraction and RDF cleaning enter the garbage, and filtrate obtained after filtering solid suspended matters (perishable organic matters, soil and the like) is high-concentration perishable organic wastewater. If the organic matters are not treated, the organic matters in the organic matters are immediately rotten to emit foul smell, the color is darkened, and the viscosity is increased. Heavy metal ions in the waste water can be accumulated after multiple cycles, and the quality of perishable organic matters is seriously influenced. The prevention of anaerobic fermentation reaction and putrefaction of the used medium water is the primary task for realizing the recycling of the medium water.

specifically, the process water treatment system comprises a process water tank to be treated, the process water tank to be treated is connected with a micro-nano bubble generator, the micro-nano bubble generator is connected with a process water reaction tank, and a washing liquor conveying pipeline is circulated at a water outlet of the process water reaction tank.
The water outlet end of the process water tank to be treated is connected with a micro-nano bubble generator, oxygen and ozone are introduced into the process water in the conveying process, or a strong oxidant is added, so that on one hand, microorganisms are killed, on the other hand, the concentration of oxygen in the water is changed to inhibit anaerobic bacteria from generating anaerobic reaction, and the circulating water can be prevented from smelling. The process selects the ozone micro-nano bubbles as a carrier to carry out circulating water treatment, increases the solubility and the residence time of ozone in process water by utilizing the micro-nano bubbles, and improves the dispersibility and the uniformity of the ozone in the water, thereby achieving the purposes of quickly killing anaerobic bacteria with low activity, promoting microorganisms with high activity to be in a dormant state and cutting off a microorganism reaction path. Ozone has strong oxidizing property, generated hydroxyl free radicals are oxidized next to fluorine with the strongest oxidizing property, organic matters which are easy to degrade in the medium water are decomposed, and the promoting effect of micro-nano bubbles can improve the oxidizing property of the ozone by 30-300%, and simultaneously reduce the COD and BOD concentrations of the medium water, so that the medium water can be recycled.
the above description is only a preferred embodiment of the present invention, and all other embodiments obtained by those skilled in the art without any inventive work shall fall within the scope of the present invention.
