Method and device for efficiently removing organic matters in sewage by using periphyton

Abstract

The invention relates to a method and device for efficiently removing organic matters in sewage by using periphyton. The method comprises the following steps: (1) design of spiral periphyton reactor; (2) spiral pipe pretreatment; (3) fixation process of periphyton; (4) design of periphyton treatment system; (5) design of integrated spiral periphyton reaction system; and (6) control of key environmental conditions. The device used by the method is an integrated spiral periphyton reaction system. The adsorption, absorption, biodegradation and other mechanisms of the periphyton are utilized and combined with the traditional precipitation and filtration processes to form the integrated spiral periphyton reactor. The device has the characteristics of high efficiency, small occupied area and high economic and environmental efficiency when being used for purifying organic pollutants in sewage or low-concentration low-C / N-ratio sewage.

Description

technical field [0001] The invention belongs to the technical field of biological environment and sewage treatment, and relates to a method for removing various organic pollutants in sewage by emerging microbial water treatment technology, in particular to a method for efficiently removing organic matter in sewage by using surrounding organisms; It relates to the equipment used in this method: an integrated spiral periplex bioreaction system. Background technique [0002] With the development of cities and the development and utilization of resources, organic pollution in my country is increasing day by day, such as micro-organic pollution of drinking water, agricultural non-point source organic drug pollution, industrial point source organic pollution, etc. According to reports, although the water treatment capacity of my country's sewage plants has reached the forefront of the world, urban sewage generally has problems such as low C / N ratio, large water temperature cha...

Problems solved by technology

Although this process can be beneficial to the cultivation and growth of various microorganisms, the controllability of the operation is not strong, and the secondary pollution of the effluent or the shedding of the biofilm is not well considered, and further improvement is needed

[0010] Assembled aerobic anaerobic immobilized microbial sewage treatment device (application publication number: CN104098179A) discloses an assembled aerobic anaerobic immobilized microbial sewage treatment device, including artificial wetland pool, water inlet pipeline, aeration device, water outlet Units and the related devices and equipment of the immobilized microbial plate, the constructed wetland pool from top to bottom is: gravel layer, aerobic immobilized microbial layer, cinder layer, anaerobic immobilized microbial layer and furfural slag layer, that is, the device The biggest feature is the organic combination of immobilized microorganisms, microbial aerobic anaerobic treatment and constructed wetland, which has certain experimental operation significance, but the efficiency and stability of the effluent treatment effect need to be further discussed. preliminary exploration stage

[0011] It can be seen that whether it is the combination of traditional water treatment technology and new microbial methods, or mainly using some emerging microbial water treatment technologies to purify sewage, it is impossible to remove pollutants in sewage once and for all, and it is even more difficult to remove low-concentration, low-C / N ratio of various organic pollutants in sewage, because there is an urgent need to develop new microbial water treatment technology
