Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 , figure 2 , image 3 ,, Figure 4shown. The raw water enters from the top of the mixing tank 1, the ozone in the ozone generator 5, the solution in the hydrogen peroxide injection tank 4, and the water enter from the bottom of the vortex pump 3 to mix with the raw water and then enter the reaction tank 2 to complete the highly oxidized contact reaction , the filter pump 9 and the filter tank 10 are arranged behind the reaction tank 2 through pipelines in sequence. Residual ozone thermal decomposer 6 is a device for treating the gas generated during ozone oxidation into harmless gas discharge, installed on the upper part of the reaction tank 2; when the filter resistance increases to the set value, stop the filter work, enter the backwashing program, first open the filter The blowdown valve at the lower part of the tank 10,...

Abstract

High oxidizing filtering system includes: high oxidizing mixing tank, high oxidizing contacting reaction pitcher, filtering pump, diatomite film filtering tank. The characteristics is that the outlet of the high oxidizing contacting reaction pitcher connects to the inlet of the filtering pump, the outlet of the filtering pump connects to the inlet of the diatomite film filtering tank, the high oxidizing mixed tank connects to the bottom of the high oxidizing contacting reaction pitcher. There are eddy current pump, ozone generator, hydrogen peroxide injection box on the bottom of the oxidizing mixed tank. There are gasholder, diatomite box, diatomite mixing box inner the diatomite film filtering tank. The beneficial effect of this invention is that high oxidizing and diatomite film combine with each other, oxidizing and filtering go along simultaneous, reducing the SS CODcr BOD of the original water as well as flavor, decolorizing, decreasing turbidity, sterilization, the wastewater according to the sullage emission standard can be reused after treatment, the river water pond water as well as ground water can reach drinking water standard after treatment.

Description

Technical field [0001] The invention relates to the technical field of waste water advanced treatment for the purpose of reuse, in particular to a system capable of highly oxidizing organic matter in waste water and having high filtering precision. Background technique [0002] Environmental protection is a basic national policy of our country. With the rapid development of the economy, the protection of the ecological environment while realizing industrialization and the restoration of blue sky and clear water have been paid great attention by governments at all levels. [0003] At present, the chemical oxidation method in wastewater treatment has received more and more attention. This technology can transform harmful organic substances into harmless compounds such as water, carbon dioxide and inorganic salts, and completely remove pollutants in water and make them harmless. change. [0004] Chlorine oxidation is the earliest water treatment chemical oxidation process appl...
