Description

High-efficient algae device that removes based on dynamic membrane separation under gravity drive

Technical Field

The utility model belongs to the field of wastewater treatment, and particularly relates to a dynamic membrane separation-based efficient algae removal device driven by gravity.

Background

At present, the problems of algae outbreak and the like common in various types of surface water bodies fundamentally need to be managed and controlled by pollution sources in the surface water, the supply of algae growth is cut off, and the problem of algae in the water bodies is radically solved. However, because of the wide range and wide source of surface water, surface water remediation and lifting work has been developed from multiple dimensions, but before the problem of surface water algae is effectively controlled, an effective algae treatment means is still lacked.

The current algae removal scheme on the market is mainly developed from the aspects of water pollution index control, chemical agent algae removal and the like. The control of the surface water quality index is to radically stop the growth and diffusion of algae, but because the surface water quantity is large, a large difference exists between the treatment efficiency and the actual demand; the chemical agent has certain timeliness for removing algae, the instant algae removal effect is obvious, the long-term algae removal effect needs continuous agent investment, and the cost is high. The utility model utilizes a membrane separation scheme and adopts a gravity driving mode, thereby obviously improving the efficiency of separating algae in the water body, reducing the energy consumption of separation and having wide application prospect in the treatment of algae in the surface water body in the current form.

Patent CN113457235A adopts a filter screen film to separate algae in water, and an automatic cleaning device sprays and cleans algae residues along the left and right sides of the filter screen film by using high-pressure spraying arms. The effect of quickly separating algae in water is realized, the filter screen membrane is effectively cleaned, and the device can reliably work under severe conditions. However, the method has complicated device structure, adopts a spray mode for cleaning and has high use cost.

Patent CN108529736B prepares a chemical agent for removing algae, ferrate and ferrous salt are compounded in proportion to obtain a ferrate composite agent, and the ferrate composite agent is added into an algae-containing water body and stirred until algae cells are settled. The chemical agent has strong oxidizing ability, fast reaction speed with algae cells, no secondary pollution, simple operation and fast effect, and ferric iron as an oxidation product is an element widely existing in the environment. However, the method for removing the algae needs to add the compound medicament for a long time, has higher cost and is not suitable for long-term large-scale use
