Municipal catalytic ozonation filter tank water treatment system

Abstract

The invention relates to the field of wastewater treatment, and discloses a municipal catalytic ozonation filter tank water treatment system which comprises a catalytic ozonation filter tank, partition plates are rotationally arranged on two opposite side walls in the catalytic ozonation filter tank, and when the two partition plates rotate to a horizontal state, the sides, close to each other, of the two partition plates abut against each other; a sliding groove is formed in the bottom of the catalytic ozonation filter tank, a collecting frame is slidably arranged in the sliding groove, sewage disposal mechanisms are arranged on the two sides of the sliding groove in the length direction and comprise push plates slidably arranged at the bottom of the catalytic ozonation filter tank and a driving air cylinder driving the push plates to slide, and the two push plates relatively slide in the direction perpendicular to the length direction of the sliding groove. When approaching each other, the two push plates are matched with the sliding grooves to form a sealing cavity, and a sealing door is arranged at one end, close to the length direction of the sliding grooves, of the side wall of the catalytic ozonation filter tank. When sludge at the bottom of the filter tank is cleaned, the influence on the water quality in the filter tank is reduced.

Description

technical field [0001] The present application relates to the field of wastewater treatment, in particular to a municipal ozone catalytic oxidation filter water treatment system. Background technique [0002] Wastewater ozone oxidation treatment is a method of purifying and disinfecting wastewater by using ozone as an oxidant. The main process facilities are composed of gas-water contact equipment. The ozone generated by the ozone generator is diffused into the water to be treated through the gas-water contact equipment, usually using a microporous diffuser, or an ejector, a turbine mixer, etc. [0003] The Chinese patent with the publication number CN112897751A discloses a large-scale municipal ozone catalytic oxidation filter water treatment system, including a sewage tank, and a collection box with an opening at the top and a height lower than the sewage tank is fixedly connected to the side of the sewage tank and the ground. The bottom of the inner wall of the sewage ta...

Problems solved by technology

[0004] In the process of realizing the present application, the inventor found that there are at least the following problems in this technology: although the above-mentioned treatment system can clean the sludge at the bottom of the filter tank, in the process of cleaning, the movement of the filter plate will cause the sludge to be separated from the filter. The clean water inside the pool mixes, polluting the clean water inside the filter
