[0039] Specifically, the shape and structure of the ecological membrane structure is fibrous, and the interior of the fibrous carbon fiber plush 2 i...

Embodiment 3

[0049] Adopt the structure of a kind of novel ecological film described in embodiment one or embodiment two, the product of the novel ecological film that obtains is as follows Figure 7As shown, the external plush system is developed, and the suitable hole and well structure covers a large range. According to the technical test of Shenzhen Huali Environmental Technology Co., Ltd., the test shows that there are as many as 3,000 to 5,000 types of microorganisms on the surface of the ecological film; the algae on the ecological base It is also the natural food of aquatic animals in the water. With the establishment of the ecosystem, multiple species appear, and the number of bait zooplankton increases, thus forming a complete food chain. The micro A / O environment on the surface of the ecological membrane base creates suitable conditions for the reproduction of nitrification and denitrification bacterial communities and the growth of algae, thereby enhancing the removal effect of ...

Abstract

The invention discloses a novel ecological membrane structure, and belongs to the technical field of sewage treatment materials. The ecological membrane structure comprises ecological membrane pores located in an ecological membrane and carbon fiber plush located outside the ecological membrane, the ecological membrane pores are formed in the carbon fiber plush, the proportion of the ecological membrane pores is 98% or above, the specific surface area of the ecological membrane structure composed of the ecological membrane pores and the carbon fiber plush is 1,300-2,200 m <2> / g, and the external specific surface area of the ecological membrane structure composed of the ecological membrane pores and the carbon fiber plush is 0.2-2.0 m <2> / g. According to the structure of the novel ecological membrane, through natural competition, flora for biofilm formation has diversity and selective symbiosis, and flagellum of the ecological membrane and the extremely large specific surface area reaching up to 1,500 m <2> / g or above are combined, so that a sewage carbon source can be maximally concentrated on the membrane to supply flora nutrients due to excellent adsorption and rich hole traps of the ecological membrane.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment materials, in particular to a novel ecological membrane structure. Background technique [0002] In sewage treatment, sewage treatment membranes are divided into two types: biofilm and filtration membrane. Biofilm is to let organisms grow on the carrier and use biosynthesis and metabolism to remove pollutants in water, that is, to use ecological technology to maximize the removal effect of sewage treatment change. [0003] Ecological technology is to establish the synergistic effect of different fungi to maximize the removal effect of sewage treatment; it is to establish a stable symbiotic relationship of fungi to create a diversity of flora; it is to fully degrade pollutants through the flora to achieve sewage treatment. Self-purification state, returning to the ecological origin of sewage treatment. [0004] In the prior art, the energy consumption of the mud-water separation of the M...
