Description

Device and method for removing phosphorus from whole-course autotrophic organisms by using mycophyte and algae symbiotic Technical Field The invention relates to the technical field of sewage treatment, in particular to a device and a method for removing phosphorus from whole-course autotrophic organisms by using a bacterial and algal symbiotic process. Background With the development of industries such as petroleum, chemical industry, food, pharmacy and the like and the continuous improvement of the living standard of people, the contents of ammonia nitrogen and phosphorus in various industrial wastewater and urban domestic sewage are increased. The excessive content of nitrogen and phosphorus elements in the water body can cause a series of ecological environment problems such as eutrophication of the water body, damage the balance of an ecological system and even harm human health. Therefore, the high-efficiency denitrification and dephosphorization of sewage is important. Compared with the traditional biological denitrification which requires a certain amount of carbon source to support the thorough progress of biological denitrification and excessive uptake of phosphorus in an aerobic section, the whole-process autotrophic process realizes high-efficiency biological denitrification by utilizing the synergistic effect of ammonia oxidizing bacteria and anaerobic ammonia oxidizing bacteria, can save about 60% of aeration amount and 100% of carbon source, and simultaneously greatly reduces capital investment, thereby being a favored process in the sewage denitrification field. However, the whole-process autotrophic process is operated without a carbon source, so that phosphorus accumulating bacteria cannot be enriched in a reaction system, the proliferation of functional microorganisms is slow, the sludge yield is low, and phosphorus cannot be removed along with the sludge discharge of the system, so that the whole-process autotrophic process does not have good phosphorus removal performance. In order to achieve the aim of high-efficiency denitrification and dephosphorization, the addition of a carbon source or a dephosphorization reagent or the coupling of other dephosphorization processes in the whole-course autotrophic system can be considered. The added carbon source tends to increase the running cost and negatively affect the growth of anammox bacteria so as to reduce the denitrification efficiency, and the added dephosphorization reagent also increases the running energy consumption of the system and has the problem of secondary pollution. Disclosure of Invention (One) solving the technical problems Based on the traditional anaerobic ammoxidation or whole-course autotrophic process, the invention provides the device and the method for removing phosphorus from the bacteria and algae symbiotic whole-course autotrophic organisms, which have the advantages of reducing the operation cost, reducing the energy consumption of a system, avoiding secondary pollution and further improving the phosphorus removal effect.
