Novel biological membrane water purifying and fountain aeration coupling device

Abstract

The invention discloses a novel biological membrane water purifying and fountain aeration coupling device. The device is characterized by comprising an organisms gathering tower, a fountain aeration system and a fixing system, wherein the organisms gathering tower comprises a round-cake-shaped hollow base, a circular-truncated-cone-shaped hollow tower body, a hydrophilic biofilm colonization carrier material and an anaerobic zone annular cover; the fountain aeration system comprises a stainless steel sleeve with screen holes, a submersible pump, a submersible pump fixing device, a plastic hose, a submersible pump power supply cable, a water conveying pipe and a fountain head; the fixing system comprises a stainless steel anchoring rod, a nylon soft rope and annular binding holes. The submersible pump arranged in a polluted river water body is used for lifting river water which is low in dissolved oxygen content, the river water makes full contact with air after being sprayed by the fountain head, the oxygen-enriched river water is sprayed to the organisms gathering tower, and the aerobic-anaerobic biological membrane purified river water is formed by means of microorganisms, algae, protozoa and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection and ecological restoration, more specifically, it relates to a novel biofilm water purification and fountain aeration coupling device. Background technique [0002] In recent years, the degree of organic pollution of river water by human sewage and other organic pollution has become more and more serious, especially the black and smelly phenomenon of urban rivers, which has brought extremely poor sensory experience to the people, and has become a prominent water environment that directly affects the production and life of the people. question. The "Water Pollution Prevention and Control Action Plan" promulgated by the State Council proposes that "by 2020, black and odorous water bodies in urban built-up areas at the prefecture level and above shall be controlled within 10%, and by 2030, black and odorous water bodies in urban built-up areas shall be eliminated in general." Target...

Problems solved by technology

Although this contact oxidation fountain aeration system uses the aeration system to increase oxygen in the polluted water body, and then performs biological purification through the microbial membrane module suspended under the water, the microbial water purification and aeration technology are organically combined, and the ecological floating The island, the microbial bed, and the fountain aeration device are improved and organically integrated to make it a whole, and the surrounding floating devices can keep the system as a whole floating freely with the fluctuation of the water level, and the horizontal displacement is very small. A grid net is set at the bottom of the buoy, which can isolate plastic garbage, leaves, paper pieces, etc. floating in the water body, and prevent these floating objects from being involved in the buoy and causing mechanical failure. The design of the outer frame of the floating island and the nylon net can Greatly improve the wind and wave resistance of the ecological floating island, extend the service life, and reduce maintenance costs. However, due to the shallow water level and large fluctuations of some black and odorous rivers, the number of microbial carriers that can be suspended is extremely limited, and the dissolved oxygen content in the water body is low. Therefore, Microbes have limited water purification efficacy and ultimately lead to limited application in shallow water channels
