Ecological floating bed with enhancement of denitrifying and dephosphorizing functions

Abstract

The invention discloses an ecological floating bed with enhancement of denitrifying and dephosphorizing functions. The ecological floating bed comprises a plastic frame formed by plastic boards, wherein the plastic frame is provided with air bags for safety; a plurality of stainless-steel frames II are arranged at the lower layer of the inner part of the plastic frame, stainless-steel frames I arearranged above a part of stainless-steel frames II, and aeration devices are arranged above the other part of stainless-steel frames II; floating plants are arranged in the stainless-steel frames I;a plurality of microbial balls are arranged in the stainless-steel frames II; water inlets are arranged at the bottom part of one side of the plastic frame, and water discharging pipes are connected at the other side of the plastic frame by water lifting pumps; the aeration devices and the water lifting pumps are respectively connected with photovoltaic power generation devices. The ecological floating bed disclosed by the invention has the beneficial effects that anaerobic-anoxic-aerobic environments for microbial spheres by the aeration devices and the floating plants, so that the diversityof microbes is improved, the denitrifying and dephosphorizing efficiency is improved and the quality of the discharged water is guaranteed; by assembled installation and up-down splitting arrangementare adopted, the structure is simple; the photovoltaic power generation devices are adopted, so that the cost for use and maintenance at the later period is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ecological floating bed with enhanced nitrogen and phosphorus removal functions. Background technique [0002] The deterioration of water quality in rivers and lakes and algae blooms are major problems restricting the construction of ecological civilization and social and economic development in our country. At present, the water bodies of rivers and lakes in my country's cities are mostly polluted by pollutants such as nitrogen, phosphorus, and organic matter, causing the water bodies of rivers and lakes to turn black and smelly, and ecological disasters (such as algae blooms) occur frequently. In recent years, under the great attention of governments at all levels, the water quality of major lakes has improved steadily, but the concentration of nitrogen and phosphorus is still high, which is the main factor affecting the water quality of rivers and lakes and the out...

Problems solved by technology

However, plant absorption and plant root adsorption have a certain removal effect on ammonia nitrogen, nitrate nitrogen and inorganic phosphorus in water, but have limited removal effect on more organic nitrogen and organic phosphorus.
