Problems solved by technology

Excessively enriched microorganisms will cause the membrane pores on the hollow fiber membrane to be blocked, thereby affecting the oxygen supply effect of the microorganisms. When the microorganisms are insufficiently supplied, the distribution of colonies outside the hollow fiber membrane will change, so it will affect the repair work of the water body. cause adverse effects

Embodiment 1

[0032] A process equipment for synchronously improving the ecological environment quality of river water bodies, the structure of which can be obtained by figure 1 Schematically, as shown in the figure, the restoration device includes: a cage, a microbial load unit 2, an ecological floating island 3 and an aeration component. The cage is used to provide an installation foundation for the microbial load unit 2, so that the microbial load unit 2 is arranged on the cage, the ecological floating island 3 is arranged directly above the microbial load unit 2, and a floating island is arranged on the ecological floating island 2. island plants. The aeration component is connected with the microorganism load unit 2, and oxygen can be delivered to the inside of the microorganism load unit 2 through the aeration component.

[0033] When working, the aeration component can guide the air in the external environment into the microbial load unit 2 , so as to provide oxygen and nutrients fo...

Embodiment 2

[0055] On the basis of the above embodiments, the device can also improve the denitrification effect on polluted water by adjusting the shape of the supporting frame 11 . Specifically, such as Figure 4 As shown, in this embodiment, the supporting frame 11 is cylindrical, and correspondingly, the microbial load unit 2 is ring-shaped, and the axis of the ring-shaped microbial load unit 2 coincides with the axis of the supporting frame 11 .

[0056] In the actual working process, the axis of the cylindrical supporting frame 11 will be perpendicular to the bottom surface of the water body. Since the air bubbles generated by the aeration component will gather toward the water surface, the microbial load unit 2 at the top will receive more oxygen supply. In this state, the top microbial load unit 2 will produce more aerobic bacteria, while the bottom microbial load unit 2 will produce more facultative anaerobes. Through the synergistic effect of aerobic bacteria and nitrifying b...

Abstract

The invention provides process equipment for synchronously improving the ecological environment quality of a river water body. The process equipment comprises a box cage, a microorganism loading unit,an ecological floating island and an aeration assembly, wherein the microorganism loading unit is arranged on the box cage, the aeration assembly is connected with the microorganism loading unit, andthe ecological floating island is arranged above the microorganism loading unit. The microorganism loading unit comprises a membrane module and protective filler, the outer wall of the membrane module is a smooth surface, and the protective filler is arranged outside the membrane module. The protective filler comprises a reticular layer and a filamentous layer, the reticular layer is in contact with the smooth surface of the membrane module, and the filamentous layer is arranged outside the reticular layer. An aerobic bacteria layer is formed on one side, close to the reticular layer, of thefilamentous layer, and a facultative anaerobic bacteria layer is formed on one side, away from the reticular layer, of the filamentous layer. According to the process equipment for synchronously improving the ecological environment quality of the river channel water body, the black and odorous water body in the river channel can be repaired, so that the water quality in the river channel is improved, and the overall attractive effect of the river channel is improved.

Description

technical field [0001] The invention belongs to the technical field of water body restoration, and in particular relates to a process equipment for synchronously improving the ecological environment quality of river water bodies. Background technique [0002] Black and odorous water is an extreme manifestation of organic pollution in water. When a large amount of organic matter enters the water, the aerobic microorganisms in the water will consume the oxygen in the water, thus turning the water into an anoxic state. Under anaerobic conditions, anaerobic bacteria will multiply in large numbers, which will cause the organic matter inside the water body to decay, decompose or ferment, and then turn the water body black and smelly. [0003] In order to repair the black and odorous water body, in the prior art, a membrane bioreactor (MBR) is installed inside the polluted water body. The membrane bioreactor can intercept and filter the water body and form a biofilm, and the biofil...
