Embodiment Construction

[0022] see figure 1 , the multi-stage basalt fiber bundle constructed wetland includes a water inlet area (water distribution area), a filter area, and a water outlet area that are sequentially arranged from bottom to top. Under the joint action of adsorption filtration and microbial degradation, the organic pollutants and nutrients such as nitrogen and phosphorus in the wastewater are effectively removed, and the purified wastewater flows out through the effluent area.

[0023] The filter area is formed by connecting five sections of hollow cylinders 6, and the cylinders 6 are filled with fillers. Wherein, the outer side of the lower port of the upper cylinder 6 is welded with a flange 13, the outer side of the upper port of the bottom cylinder 6 is welded with a flange 13, and the outer side of the upper port and the lower port of the middle cylinder 6 are welded with a flange 13. Each flange 13 is provided with 8 holes, and the end face of each flange 13 is provided with a...

Abstract

The invention discloses a multi-section basalt fiber bundle combined packing artificial wetland which comprises a filtering zone, wherein the filtering zone is filled with multi-layer packing; the multi-layer packing comprises a granular packing layer, a basalt fiber bundle layer and a soil or sand layer; wastewater flows in from the bottom of the filtering zone and flows out from the upper part of the filtering zone. By adopting the wetland, a basalt fiber is creatively combined with conventional granular packing, novel packing can be molded, a synergetic treatment effect of three components,namely a matrix, microorganisms and plants, is brought into play to the maximum extent, the multi-section basalt fiber bundle combined packing artificial wetland is made of basalt fiber bundles as abiological carrier, is beneficial to growth and propagation of microorganisms, is capable of sufficiently bringing a microorganism degradation function into play, meanwhile has multiple advantages ofa conventional artificial wetland, and is an efficient and feasible sewage treatment device.

Description

technical field [0001] The invention relates to an organic sewage (waste) water treatment device, in particular to an artificial wetland filled with multi-segment basalt fiber bundles. Background technique [0002] As a new type of ecological sewage treatment technology, constructed wetland utilizes the combined effect of plants-matrix-microbes in the ecosystem to exert the triple synergy of physics, chemistry and biology to purify sewage. Due to the advantages of low construction cost, low operating cost, easy operation, and good treatment effect, it has been rapidly developed and applied in the treatment of various organic sewage (waste) water and the ecological restoration of slightly polluted water bodies. [0003] In the process of removing various pollutants in water bodies in constructed wetlands, microorganisms, as the decomposers of the system, play a very critical role. As a microbial carrier, the constructed wetland filler provides a stable attachment surface for...
