Reactor for implementing static cultivation and continuous growth of aerobic filamentous biological membranes

Abstract

The invention discloses a reactor for implementing static cultivation and continuous growth of aerobic filamentous biological membranes. The reactor comprises a feeding tank, a peristaltic pump, an aeration pump, a gas flow meter, a reaction tank, a carrier supporting frame, an upper partition plate, upper guide pipes, vascular carriers, a lower partition plate, lower guide pipes, supporting seats, a porous aeration pipe and a fence. Pumped gas is regulated through the gas flow meter and then enters the porous aeration pipe to form bubbles, the bubbles are gathered by the fence and the supporting seats and promote and drive wastewater to flow upwards through the interior of the vascular carriers by hollow passages formed by the lower guide pipes, the vascular carriers and the upper guide pipes, direct impact of the bubbles and wastewater on the aerobic filamentous biological membranes is avoided, the aerobic filamentous biological membranes in the reactor acquire oxygen and nutrients from the interior of the vascular carriers, and accordingly aging and death of the aerobic filamentous biological membranes attached to the vascular carriers in the reactor due to deficiency of oxygenand nutrients are avoided, and the problem of complete shedding of the aerobic filamentous biological membranes from the vascular carriers is solved.

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. technical background [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
