Example Embodiment

[0016] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0017] like figure 1 and figure 2 Shown, a kind of photocatalytic-biochemical integrated reactor comprises reactor body 1, and the middle part of this reactor body 1 is provided with horizontal filter sieve plate 7, and the edge of this filter sieve plate 7 and described reactor body The inner wall of 1 is fixedly connected, and the filter sieve plate 7 is a 10-mesh sieve plate. The filter sieve plate 7 divides the reactor body 1 into upper and lower parts. The upper part of the reactor body 1 is a photocatalytic zone. The lower part of the body 1 is an oxygen-deficient area, and three high-pressure mercury lamp tubes 2 are arranged in the photocatalytic area. On the inner wall of the device body 1, the high-pressure mercury lamp tube 2 is connected to a power supply through a wire, and a photocatalyst layer 4 is arranged on the inner wall of the hig...

Abstract

The invention discloses a photo-catalytic/biochemical integrated reactor, which includes a reactor body. An upper part of the reactor body is a photo-catalytic zone and a lower part of the reactor body is an anoxic zone. At least one high-pressure mercury lamp tube is arranged in the photo-catalytic zone, wherein a photo-catalyst layer is formed on inner wall of each high-pressure mercury lamp tube. A filling material is arranged in the anoxic zone. The photo-catalytic/biochemical integrated reactor has the following significant effect: in the photo-catalytic zone, hydrogen peroxide and high-active hydroxyl free radicals are generated and are used for degrading organic substances, dyes and a part of toxic substances, which are difficult to degrade biologically and is slow in biological degradation, in waste water, thereby providing an excellent input condition to the anoxic zone at the lower part and further improving water bio-chemical treatment efficiency and water bio-chemical treatment effect in the anoxic zone.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a photocatalytic-biochemical integrated reactor. Background technique [0002] Biological treatment of sewage is a new technology that appeared at the end of the 19th century. It has become one of the main means of sewage treatment in countries all over the world. The organic pollutants in wastewater are degraded through the metabolic activities of microorganisms on activated sludge or biofilm. To purify the sewage. Due to the remarkable advantages of low consumption, low operating cost, simple process, convenient operation and management, and no secondary pollution, biological treatment has attracted more and more attention, and has been actively developed and applied all over the world, and has achieved great results. Good economic and social benefits. With the development of industry, especially with the development of petroleum, chemical industry, textile and other industries, s...
