Embodiment Construction

[0010] One embodiment of the present invention is to process the high-concentration organic waste water of pesticide factory, and its technological process is:

[0011] High-concentration organic wastewater (1) first passes through the grid and enters the regulating tank for pretreatment (2): it can stabilize the water quality and quantity and remove some low-boiling point organic substances in the wastewater, and can purify certain harmful substances in the wastewater. removal or cracking. When the organic wastewater is relatively stable and clean, the pretreatment (2) step can be omitted, that is, the organic wastewater (1) directly enters the next step (3).

[0012] The wastewater from the pretreatment (2) of the self-regulating tank, or the organic wastewater (1) directly enters the microwave catalysis (3), and there is a solid catalyst in the microwave catalytic reactor, which is in direct contact with the wastewater, under the action of microwaves of a certain wavelength...

Abstract

The invention provides a method for treating high-concentration organic wastewater through microwave cyclic catalysis. The method uses a special composite solid catalyst (HFC) and microwaves to act on high-concentration wastewater synergically so as to catalytically crack the H-O, C-H and H-H bonds of organic matter; under the action of the microwaves, the H-containing bonds in the organic matterare rapidly broken so as to crack the macromolecular organic matter into small molecular matter; and through cyclic catalysis treatment, the COD of the wastewater is progressively changed and lowered, and the B / C value of the wastewater is raised. The method is a novel wastewater treatment technique which is high in efficiency, low in consumption and free from secondary pollution, and solves the technical problem of treating high-concentration and high-salinity organic wastewater in pesticide, pharmaceutical, chemical and other industries.

Description

technical field [0001] The invention relates to a method for treating high-concentration organic waste water, in particular to a method for microwave circulation catalytic treatment of high-concentration organic waste water. Background technique [0002] Microwave wastewater treatment technology is a new technology for wastewater treatment with high efficiency, low consumption and no secondary pollution. This technology has developed rapidly in our country. He solved a large number of chemical wastewater treatment problems that were previously difficult to control, or had extremely high investment and operating costs, and made a breakthrough in the treatment of high-concentration organic wastewater. However, simple microwave treatment cannot solve some special organic wastewater that has no obvious effect on microwave, such as wastewater from pesticide and pharmaceutical industries, and the treatment effect is not good. Contents of the invention [0003] The invention pro...
