Abstract

The invention discloses catalyst packing and a catalytic oxidation defoaming device thereof. The catalyst packing is basically made of activated carbon and is prepared by soaking the activated carbon in copper sulfate solution with the mass percent of 3-8% for 20-28h and then sintering for copper curing at the temperature of 270-330 DEG C. The catalytic oxidation defoaming device comprises a tank, a water inlet pipe, a gas inlet pipe, a catalytic packing area and a water outlet pipe, wherein the catalyst packing is filled in the catalytic packing area. The catalyst packing and the catalytic oxidation defoaming device can be applied to industrial wastewater treatment for electroplating, circuit board and printing and dyeing industries and can guarantee subsequent treatment not to be disturbed by foam; and the catalytic oxidation defoaming device small in floor area basically has no influence on an original process, thereby being particularly applicable to reconstruction projects of enterprises.

Description

technical field [0001] The invention relates to the technical field of catalysis, in particular to a catalyst packing and a catalytic oxidation defoaming device thereof. Background technique [0002] The cleaning wastewater generated by printing and dyeing, circuit board, electroplating and other enterprises will generate a lot of foam during the treatment process, which seriously affects the operating environment and facility operation. [0003] The circuit board wastewater treatment process is as follows: [0004] Circuit board wastewater → regulating pool → lifting pump → coagulation reaction tank → inclined tube sedimentation tank → callback pool → standard discharge or advanced treatment. [0005] Printing and dyeing wastewater treatment process: [0006] Printing and dyeing wastewater → regulating tank → lifting pump → coagulation reaction tank → inclined tube sedimentation tank → callback tank → anaerobic tank → aerobic tank → sedimentation tank → standard discharge...
