Description
Technical field
The utility model belongs to technical field of sewage, especially relates to a kind of catalytic ozonation contact tank.
Background technology
Ozone has strong oxidizing property, after being dissolved in water, can remove foreign odor, pigment and microchemistry composition.The effect of ozone in sewage disposal is more and more taken seriously.
Catalytic ozonation technique, by causing the hydroxyl radical free radical with Strong oxdiative ability, high stability, Persistent organic pollutants in strengthening water of decomposition, improve several times to the decomposition efficiency of high stability organic pollutant than simple ozone oxidation.Catalyzer also can improve ozone in water capacity of decomposition, increases the concentration of oxygen in water, and the depollution effect of strengthening subsequent biological processing unit.
Summary of the invention
The purpose of this utility model is to provide a kind of catalytic ozonation contact tank, for the purifying treatment of sewage work's sewage.
A kind of catalytic ozonation contact tank, its two ends, top are respectively equipped with water-in, water outlet, spray equipment is equipped with in the below of water-in, contact tank pond body is built with polylith baffle plate, pond body is evenly divided into some little Chi, baffle plate size is identical, adjacent two pieces of baffle plates are staggered installation of up and down, certain altitude difference is left bottom upper baffle plate and pond body, under baffle plate be connected with pond body bottom vertical, solid catalyst is filled near the little Chi of inlet end, near the in-built gac of little Chi of water outlet end, bottom the body of contact tank pond, microporous diaphragm aerator is housed, microporous diaphragm aerator is connected with the ozonizer of catalytic ozonation contact tank outside.
Described baffle number is determined according to pond body size and concentration of wastewater.Concentration of wastewater is high, and baffle number can be more.The little Chi quantity of dress solid catalyst also can be determined by concentration of wastewater.
Described solid catalyst is be carried on the bimetallic catalyst on haydite and gac, as MnO
22Fe
2o
3, MnO
22CuO, Mn
22Co

4deng.This catalyzer has high conversion, the advantage such as activity stabilized.
The loadings of described solid catalyst is 1/4 ~ 1/3 of contact tank pond height.
The polylith baffle plate installed additional in catalytic ozonation contact tank, is divided into several little Chi by contact tank, mainly in order to extend the duration of contact of waste water and catalyzer, improve the service efficiency of catalyzer simultaneously.
Catalytic ozonation contact tank of the present utility model makes with stainless steel or other material of liner oxidation corrosion protection coating is made.The reaction activity that catalytic ozonation contact tank of the present utility model utilizes solid catalyst synergy ozone to be oxidized can to reduce wastewater treatment process or change reaction mechanism, thus reach deep oxidation, remove organic pollutant to greatest extent.
