Method for treating organic matters in constructed wetland

Abstract

The invention discloses a method for treating organic matters in a constructed wetland. An electric energy storage module, a refrigeration module, a low-temperature simulation module and a wetland experiment area are adopted. The wetland experiment area comprises a wetland partition pool. The electric energy storage module comprises an energy storage box and a solar panel. The refrigeration module comprises a refrigeration box, an air-cooled water chiller, a frequency converter and an air cooler. The low-temperature simulation module comprises a supporting coaming, a heat-insulating light-transmitting cover and a cold air pipe. According to the invention, the constructed wetland partition pool is used for the experiment of treatment of organic matters in a wetland, under the condition that a qualified wetland environment is formed, the upper end of the wetland partition pool is sealed and covered by adopting the supporting coaming and the heat-insulating light-transmitting cover, then the air-cooled water chiller is used for refrigeration, and the cold air is fed into the wetland partition pool by the air cooler through the cold air pipe. According to the method, the organic matter decomposition efficiency of the low-temperature microbial flora is well improved, meanwhile, a solar energy storage mode is adopted in an electric power energy supply part, and good environment-friendly and energy-saving effects are achieved.

Description

technical field [0001] The invention mainly relates to the technical field of wetland treatment of organic matter, in particular to a method for treating organic matter in artificial wetland. Background technique [0002] Constructed wetland, as a low investment, low energy consumption, low treatment cost and good nitrogen and phosphorus removal function, has been gradually accepted by countries all over the world. Its principle is mainly to use the relationship between substrate, aquatic plants and microorganisms in wetland The interaction among them, through a series of physical, chemical and biological ways to purify sewage. In recent years, scholars at home and abroad have done a lot of research on the engineering application and purification mechanism of constructed wetlands in sewage treatment; in the wetland system The structure, water distribution and combination types have also been deeply explored. Because of its good pollutant removal effect and wide applicability...

Problems solved by technology

[0003] As the main body and core of constructed wetland decontamination, microorganisms play a key role in the mineralization, nitrification, denitrification and other processes of substances. Low-temperature microorganisms are one of extremophile microorganisms. They have unique physiological functions to adapt to the environment, so research on this kind Microorganisms not only have important theoretical significance, but also produce increasingly obvious economic and environmental benefits in practical application. Regarding low-temperature bacteria, the current research of domestic scientists is mainly focused on the isolation, screening and identification of low-temperature bacteria. The application of water treatment is also limited to the treatment of simulated wastewater under laboratory temperature control conditions. There are very few studies on low-temperature microorganisms in sewage treatment in constructed wetlands, and the existing constructed wetlands are relatively insufficient for the construction of low-temperature environments. , therefore, it is necessary to develop a method for the treatment of organic matter in constructed wetlands that can sustainably maintain a low temperature environment
