Net-like basalt fiber combined-type baffling artificial wetland system

Abstract

The invention provides a net-like basalt fiber combined-type baffling artificial wetland system. The net-like basalt fiber combined-type baffling artificial wetland system comprises a pool body, an artificial wetland sewage distributing area, an artificial wetland effluent collecting area, and separating sections, wherein the separating sections are arranged at interval so that the pool body is separated into conventional filler sections, the pool body comprises a bottom wall, long side walls and short side walls, the artificial wetland sewage distributing area and the artificial wetland effluent collecting area are respectively positioned at the outer sides of the two short side walls, the separating sections are installed parallel to the short side walls and butted with the bottom wall,the separating sections are extended in a direction from one long side wall to the other long side wall, the separating section comprises a separating plate and a net-like basalt fiber filler base groove, two neighboring separating sections are reversely installed, two neighboring conventional filler sections are communicated by the net-like basalt fiber filler base groove. Compared with the priorart, the net-like basalt fiber combined-type baffling artificial wetland system is capable of adopting a basalt fiber base material, and efficiently defouling, and good in effluent quality.

Description

technical field [0001] The invention belongs to the field of organic sewage (waste) water treatment and resource utilization, and in particular relates to a reticular basalt fiber composite baffle constructed wetland system. Background technique [0002] Constructed wetland sewage treatment system is an ecological sewage treatment technology that simulates natural wetlands and is artificially constructed and supervised. It makes full use of the physical, chemical and biological triple synergies of the plant-matrix-microbial complex ecosystem in the constructed wetland to purify sewage. Due to its low construction and operating costs, good ecological benefits, and the ability to use renewable energy, it has been rapidly developed and recognized in the treatment of various organic sewage (waste) water and the ecological restoration of slightly polluted water bodies. Promote apps. [0003] At present, the constructed wetland sewage treatment system mainly includes surface flo...

AI Technical Summary

Problems solved by technology

[0005] As an important part of constructed wetlands, fillers directly purify and remove pollutants through physical and chemical methods such as absorption, adsorption, ion exchange, and complexation reactions. On the other hand, they provide carriers for the growth of plants and microorganisms in constructed wetlands. Affects the purification effect of the system

Traditional constructed wetland fillers include soil, gravel, zeolite, limestone, fly ash, ceramics and plastics, etc., mainly granular materials, which more or less have small contact area, low porosity, low microbial attachment efficiency, and easy clogging and other shortcomings

With the emergence of various new materials, there have been relatively successful application cases of fiber materials as carrier substrates in the field of water treatment, such as carbon fiber and bamboo fiber, etc., but the high cost of such materials or the high pollution in the production process are also daunting
