Problems solved by technology

The construction cost of surface flow constructed wetland is relatively low, but the area is larger than that of subsurface flow and vertical flow constructed wetland, and the surface is easy to freeze in winter, and mosquitoes are easy to breed in summer, and there is a bad smell
The advantage of subsurface flow constructed wetlands is that it makes full use of the wetland space, exerts the synergy between systems, and has good sanitation conditions, but the construction cost is higher than that of surface flow constructed wetlands
Vertical submerged constructed wetlands have better denitrification and phosphorus removal effects, occupy a small area, and have good oxygen supply, but the construction cost is higher than other constructed wetlands

Abstract

The invention discloses immobilized functional filler of an artificial wetland. The immobilized functional filler comprises the following chemical components in parts by weight: 0.20-2.99 parts of CaO, 29.30-38.98 parts of Mg, 33.69-49.76 parts of SiO2, 0.38-2.01 parts of Al2O3, 0.76-4.82 parts of Fe2O3, 0.23-0.68 part of Cr2O3, 1.94-4.44 parts of FeO, 0.01-0.05 part of TiO2, 0.05-0.14 part of MnO, 0.11-0.19 part of K2O+Na2O, 0.01-0.04 part of P2O3, 6.52-13.59 parts of H2O<+> and 0.22-6.73 parts of CO2. The immobilized functional filler disclosed by the invention has a very large specific surface area and a lot of microorganisms can grow on the surface in an immobilized manner; the content of active bacteria is more than or equal to 1 million / gram; and the microorganisms in a biological film can be used for absorbing and decomposing organic matters in water, so that sewage is purified.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a constructed wetland immobilized functional filler. A unique sewage treatment comprehensive ecosystem composed of substrates, plants, microorganisms and water bodies is constructed. It is a wastewater treatment technology that integrates physical, chemical, and biochemical reactions. It achieves efficient purification of sewage through filtration, adsorption, co-precipitation, ion exchange, chemical degradation, plant absorption, and microbial decomposition. Background technique [0002] According to the characteristics of water flow, constructed wetlands can be divided into three types: surface flow constructed wetlands, subsurface flow constructed wetlands, and vertical flow constructed wetlands. The construction cost of surface flow constructed wetlands is relatively low, but the occupied area is larger than that of subsurface flow and vertical flow constructed wetla...
