Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of sewage treatment equipment, and in particular to a sewage deep phosphorus removal device. Background Art
[0002] In recent years, with the continuous increase in the scale of rural urbanization in my country, the urban population density has become higher and higher with the development of modernization. At the same time, with the improvement of people's living standards, a large amount of phosphorus-containing domestic sewage has been generated. This causes excessive nutrients to enter the water body, causing abnormal reproduction of algae and aquatic plants in the water body, that is, eutrophication of the water body. For cities, with the increase in population, the amount of sewage discharged has also increased exponentially. Even if the current sewage treatment plants have better treatment and control of pollutants in sewage, the total discharge, especially the total amount of nutrient-rich nitrogen and phosphorus, has far exceeded the self-purification capacity of the environment. Therefore, the corresponding domestic sewage discharge standards are increasingly required, and further deep phosphorus removal is imminent. Therefore, it is of great practical significance to study the deep and efficient phosphorus removal technology of domestic sewage.
[0003] The research and application of phosphorus removal technology has a history of many years. The existing sewage phosphorus removal processes at home and abroad mainly include biological phosphorus removal and chemical phosphorus removal. At present, sewage treatment plants mainly rely on biological phosphorus removal, but due to the influence of factors such as the total phosphorus (TP) concentration of the influent, the environment and management, the TP of the effluent is unstable and cannot meet the relevant process requirements for upgrading and transformation. Especially when the effluent standard is raised to Class A, it is difficult to meet the emission standards relying solely on biological phosphorus removal. In order to remove pollutants that cannot be effectively and stably removed in biological phosphorus removal, chemical phosphorus removal is usually added as an auxiliary. Chemical phosphorus removal is mostly done by adding chemical agents. However, in the prior art, the contact time between the chemical agent and the pollutant is limited, and incomplete reactions are prone to occur. Moreover, the utilization efficiency of the chemical agent is low. Summary of the invention
