[0032] The waterway one 101 includes ozone waterway and raw water waterway, the ozone waterway passes through the output end of the ozone generator 2 and is connected with the ozone generator 2, and the raw water waterway is directly connected to the oxidation tank 3.

[0034] The pH adjusting mechanism 4 includes pH adjusting end, NaCIO end and PAC dosing point end, and the pH adjusting end, NaCIO end and PAC dosing point end are all connected to the waterway two 102 through check valve.

[0035] The waterway two 102 is connected with pipeline mixer 5 between the air floatation device 6.

[0036] The air floatation device 6 includes skimming machine cover 601 for scraping off the scum layer of the air floatation device 6, the skimming machine cover 601 is located at the top of the air floatation device 6, the output end of the skimming machine cover 601 is connected with scum collection tank, and the scum collection tank is provided with scum discharge port.

[0037] The air floatation device 6 includes air floatation tank, and the air floatation tank is a solid-liquid separation process, mainly used for treating small suspended matters and colloids with relative density close to water in raw water which are difficult to remove by sedimentation.

[0038] A large number of fine and uniform nanometer bubbles are formed in the air flotation process of the air flotation tank, the fine bubbles serve as carriers, fully mix with, contact and adhere to the suspended flocculation particles in water to form air-entrained flocculation which floats to the surface of the liquid. The three-phase mixture of bubbles, water and flocculation (suspended matter, algae and the like) is collected by a skimmer to achieve the purpose of separating impurities and purifying water.

[0039] The air flotation tank is composed of an air flotation tank body, a dissolved air device, an air compressor, a rack and a control cabinet.

[0048] The filter water purification mechanism 8 includes a ceramic ultrafiltration integrated water purification device, which is mainly used for separating suspended solids, colloidal particles and bacteria. However, the retained substances will accumulate on the membrane surface, which will cause the filtration flux of the membrane to decrease. In order to ensure longer service life and better filtration effect of the ultrafiltration integrated water purification device, the ceramic membrane 803 needs to be operated regularly, such as backwashing, air washing, forward washing, ozone water soaking, chemical strengthening backwashing and chemical cleaning.

[0058] In filter water purification mechanism 8, the water is filtered through ceramic membrane 803, and the purified water is partially output into clean water tank 10 through a final output end and is then output by water supply water path 1001; and the other part of the water enters backwash water tank 901 of backwash mechanism 9, and when it is necessary to backwash filter water purification mechanism 8, backwash water pump 902 is started to reversely flush ceramic membrane 803 through a backwash water path to remove the pollutants on the membrane surface and ensure the filtering effect.
