Embodiment Construction

[0019] see Figure 1-5 .

[0020] The assembly of the flange cover 3 and the detachable hollow fiber membrane module 14 is performed first. Commercially available hollow fiber membranes are used, with an outer diameter of 1.5mm, an inner diameter of 0.85mm, and a membrane pore diameter of 0.01um. Each group of detachable hollow fiber membrane modules 14 has a total of 6,000 hollow fiber membranes, and the effective membrane area is 45m 2 , two sets of detachable hollow fiber membrane modules 14 are set up. The top and bottom ends of 6000 hollow fiber membranes are inserted into the membrane module end sleeve 11, and then all the hollow fiber membrane ends are sealed with the fiber membrane sealant 12. The end sleeve 11 of the membrane module is bonded and fixed, and the membranes of the hollow fiber membranes are also completely sealed with a fiber membrane sealant 12, but the openings of the hollow fiber membranes are not sealed, so that hydrogen can be released from the top...

Abstract

The invention relates to a device for processing oxidizing pollutants in drinking water. A barrel (13) is provided with an underwater agitator (19) at the inner bottom, a fixed support device (17) fixedly joined with the inner wall at the lower part and a detachable hollow-fiber membrane module (14) at the inner part, which fixedly joins and seals a hollow-fiber membrane and a membrane module end sleeve (11) at the two ends through a fibrous membrane sealant (12). The membrane module end sleeve (11) is respectively connected with a membrane module bracket (15) at the bottom end and a membrane module fastener (4) fixedly joined with a flange cover (3) at the top end through an internal thread fastening sleeve (10) and the flange cover (3) is provided with a hydrogen tube joint (2). The device can be used after well assembling the membrane module bracket (15) and the fixed support device (17) and enveloping the flange cover (3). The invention has reasonable structure and easy assembly and disassembly of the hollow-fiber membrane module, and can remove various oxidizing pollutants in drinking water, and electron donor hydrogen is clean and has the features of high efficiency, low cost and no need of subsequent treatment.

Description

technical field [0001] The invention relates to a device for treating oxidative pollutants in drinking water, which belongs to the technical field of treatment of oxidative pollutants in drinking water in environmental engineering, in particular to a device for purifying polluted water by using hydrogen autotrophic bacteria biofilm. Background technique [0002] In many areas of our country, the pollution of oxidative pollutants in drinking water is quite serious. These oxidative substances mainly include nitrate, high-valent heavy metal substances and volatile organic substances such as chloroform. Drinking water contaminated with high concentrations of nitrates can easily lead to "blue baby syndrome" after being drunk by infants and young children. In order to improve the safety of drinking water, many countries in the world have set standards for the concentration of nitrate and nitrite in drinking water. The World Health Organization (WHO) stipulates that the content of ...
