A reactor for static culture and continuous growth of aerobic filamentous biofilm

Abstract

The invention discloses a reactor for realizing static culture and continuous growth of aerobic filamentous biofilm, which comprises a feed tank, a peristaltic pump, an aeration pump, a gas flow meter, a reaction tank, a carrier bracket, an upper partition, an upper conduit, Vessel carrier, lower baffle, downcomer, support, microporous aeration tube, enclosure; the gas pumped by the present invention enters the microporous aeration tube through the adjustment of the gas flow meter to form air bubbles, enclosure and support The bubbles are gathered, and the bubbles pass through the hollow channel formed by the downcomer, the vascular carrier, and the upper catheter, which promotes and drives the waste water to flow upward through the inside of the vascular carrier, avoiding the direct impact of the air bubbles and waste water on the aerobic filamentous biofilm, and realizing the reactor The aerobic filamentous biofilm in the vascular carrier obtains oxygen and nutrients from the inside of the vascular carrier, thereby avoiding the aging and death of the filamentous biofilm close to the vascular carrier in the reactor due to hypoxia and nutrition, and solving the problem of filamentous The problem of complete detachment of biofilms from vascular supports.

Description

technical field [0001] The invention belongs to the field of microorganism application, and in particular relates to a reactor for realizing static culture and continuous growth of aerobic filamentous biofilm. Background technique [0002] The accumulation and persistence of refractory organic pollutants in the environment have seriously endangered the health of the ecosystem and the sustainable development of human society. In addition to being refractory, these pollutants also have high biological toxicity, carcinogenicity, teratogenicity, and carcinogenicity. Mutation hazard is the focus and difficulty of environmental governance and protection. These pollutants in the environment enter the water body and are difficult to remove by traditional treatment methods. It is necessary to study new methods and new technologies to solve the increasingly prominent environmental problems caused by these pollutants. White rot fungi can degrade a variety of refractory organic compound...

AI Technical Summary

Problems solved by technology

[0003] Although different types of reactors have certain treatment effects on different types of refractory organic wastewater, it is difficult for these reactors to operate continuously and stably for a long time. White rot fungi cannot grow continuously and stably in these reactors. As a result, these reactors cannot operate continuously and stably for a long time, and eventually lead to the collapse of the entire degradation system

[0004] The immobilized culture of white rot fungi is conducive to the maintenance of their activity. However, immobilized microorganisms often have the problem of biofilm shedding. Due to the lack of nutrients and oxygen obtained by the biofilm, the carrier is subjected to shear force during use. The role of biofilm is easy to fall off and cannot grow continuously and stably
