The invention discloses a method for the advanced treatment of wastewater. The method comprises the following steps of: 1) filtering off-standard wastewater, delivering the wastewater into a catalytic ozonation tower, and simultaneously adding ozone for contact oxidization reaction; 2) delivering the effluent of the catalytic ozonation tower into an oxidization buffer stabilization basin for stabilization; 3) and after the stabilization, delivering the effluent into a BAF basin for treatment, and delivering discharged water into a clean water basin. The method reduces the addition amount of the ozone, improves the utilization efficiency of the ozone, converts the ozone into hydroxyl radicals by using a metal catalyst, and reduces the activation energy of hydroxyl radical oxidation reaction to promote hardly biodegradable macromolecule organic substances in the wastewater to be oxidized into easily biodegradable micromolecule substances, so that the biochemical limit to refining the wastewater is broken through and the biodegradability of the wastewater is increased; and the water quality of the effluent can meet the provincial standard of Jiangsu province, namely Chemical IndustryMain Water Pollutant Discharge Standard, completely by further treatment in the BAF basin.

The invention relates to a kitchen waste treatment process. The kitchen waste treatment process comprises the following steps: (1) carrying out pretreatment for dividing the kitchen waste into a solid-phase material, an oil-phase material and a water-phase material through a pretreatment system; (2) carrying out primary filtering treatment for introducing the water-phase material into a first filtering system, wherein the first filtering system comprises a first filtering film component, the water-phase material is filtered by a cross flow filtration manner through the first filtering film component, the obtained filtrate is primary treatment water, and the trapped molecular weight of the first filtering film is 250000; and (3) carrying out secondary filtering treatment for introducing the primary treatment water into a second filtering system, wherein the second filtering system comprises a second filtering film component, the primary treatment water is filtered by a roll type filtering manner through the second filtering film component, the obtained filtrate is dischargeable water, and the trapped molecular weight of the second filtering film is 100. The treatment process is capable of effectively removing pollutants in the kitchen waste; the obtained water is clear and transparent and meets the discharge standard; in addition, the water production rate of the treatment process reaches over 85 percent.
