Manufacturing method of netted catalyst for degrading organic pollutant in wastewater by photocatalysis

The invention relates to a manufacturing method of a netted catalyst for degrading the organic pollutant in wastewater by photocatalysis and a wastewater treating device. The manufacturing method comprises: using the wire net plated with nickel as a carrier, coating a catalyst for solidification, wherein the catalyst mixed liquid includes nano TiO2, acetone, epoxy resin, solidifying agent and appropriate plasticizer, soaking in the acetone solution. A case of the treatment device is provided with a plurality of independent deflecting chambers connected end-to-end in turn, two ends of which areprovided with a water inlet and a water outlet. A plurality of solid netted bodies solidified with the catalyst are overlapped at intervals in the deflecting chamber. A through hole is opened in themiddle of the solid netted body. An ultraviolet light source is inserted in the through hole. An aeration pipe is arranged on the bottom of the deflecting chamber. The device can deeply degrade the organic matter in wastewater
