Problems solved by technology

In addition, many of the catalysts developed in the laboratory are in the form of powder or even nanometers, and the active components are easy to dissolve, which reduces the service life of the catalyst.
Therefore, the production cost of wastewater treatment by ozone oxidation is high, and it is not effective for every COD substance

Abstract

Provided are a water treatment catalyst and a production method and application thereof. The water treatment catalyst is prepared by the following materials according to weight percentage: 0-30% of manganese dioxide, 0-25% of aluminum oxide, 0-30% of titanium dioxide, 0-15% of cobaltosic oxide, 3-8% of carbon powder and the balance being pot clay. The production method of the water treatment catalyst includes the following steps: (1) powder grinding; (2) pelleting; (3) drying and (4) roasting. The application of the water treatment catalyst in ozone catalyzing and waste water treatment is further provided. The water treatment catalyst is used in ozone method water treatment, can efficiently remove chemical oxygen demand (COD) materials in waste water and difficult to treat, improves ozone use ratio, greatly reduces waste water treatment production cost, and can ensure that discharged waste water reaches the national discharge standard or meets recycle water quality requirements due to the fact that after ozone catalyzing and waste water treatment, content of organics in waste water and difficult to be degraded biologically is smaller than 5mg / L.

Description

technical field [0001] The invention relates to a water treatment catalyst and its production method and application, in particular to a water treatment catalyst used for ozone catalytic oxidation to remove refractory organic matter in wastewater, its production method and application. Background technique [0002] With the rapid development of the economy, many industrial enterprises have a serious shortage of water resources. In this situation, in line with the principle of saving water, reducing consumption, and being beneficial to environmental protection, and following the guideline of "increasing production without increasing water", making full use of waste water resources, turning waste into treasure, and improving water utilization have become the top priority of all enterprises. As one of the key areas of industrial water conservation, petrochemical, iron and steel industries and other industries that discharge organic wastewater need to improve the treatment and r...
