Abstract
The invention provides a geothermal heating sewage treatment system for an artificial horizontal subsurface flow wetland. At least two groups of circulating geothermal heating assemblies are distributed in an insulation wetland bed; two sides of the insulation wetland bed are respectively connected with a buried porous water distribution assembly and a porous outflow assembly; thermal insulation stone slabs are paved on the bottom and the periphery of the insulation wetland bed; packing is arranged on the thermal insulation stone slab at the bottom of the insulation wetland bed; cold-resistant wetland plants are planted in the packing. Low-grade heat energy is extracted to supply to the artificial wetland bed to maintain relatively high temperature in winter by using abundant geothermal resources under the condition of consuming less high-grade energy, and the geothermal heating sewage treatment system has an excellent heat preservation effect, so as to improve the physiological activity of matrix microorganisms and plants, thereby improving the sewage purification effect of the artificial wetland in a cold state in winter. The geothermal heating sewage treatment system is simple in structure, and low in construction and maintenance costs, does not need complicated management and staff nursing, can be widely applied to purification treatment of sanitary sewage, aquaculture sewage and non-point source pollution water in a cold region in winter, and has a broad development prospect.
Description
technical field [0001] The present invention relates to the technical field of sewage ecological treatment, in particular to a technical method for horizontal subsurface flow artificial wetland treatment suitable for efficient treatment of winter sewage in cold regions, and also relates to a horizontal subsurface flow artificial wetland sewage efficient treatment system for geothermal self-heating in cold regions. It is suitable for purification treatment of sewage in cold regions in winter. Background technique [0002] Constructed wetland is a new sewage ecological treatment technology. It can simultaneously use the adsorption and precipitation of filler matrix, and a series of physical, chemical and biological reactions of microorganisms and wetland plants to purify sewage. It has high efficiency, low cost, and easy Management and other characteristics, and has a certain ecological landscape value, especially suitable for centralized purification treatment of rural domest...
