Abstract
The invention provides a bionic natural circulation water purification device which comprises a tank body, wherein the tank body is internally provided with a pretreatment cavity, a first aerobic reaction cavity, a second aerobic reaction cavity, an anaerobic reaction cavity and an adsorption cavity that are communicated in sequence; the first aerobic reaction cavity is internally provided with a rotten wood layer, and a nitric acid stone layer is arranged on the rotten wood layer; the second aerobic reaction cavity is internally provided with a biological carbon packing layer, and a first limestone layer is arranged on the biological carbon packing layer; the anaerobic reaction cavity is internally provided with a dephosphorization material layer, and a second limestone layer is arranged on the dephosphorization material layer; and the adsorption cavity is internally provided with a charcoal layer, and a third limestone layer is arranged on the charcoal layer. According to the bionic natural circulation water purification device, used purification materials include coal, rotten wood, nitric acid stone, limestone and the like which are natural materials, so that the secondary pollution is very slight.
Description
technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a bionic natural circulation water purification device. Background technique [0002] In the production process of papermaking, petrochemical, food, printing and dyeing, coal, metallurgy and mining industries, a certain amount of sewage and sludge will be generated. The direct discharge of these sewage and sludge will cause serious damage to the environment, so it needs to be treated accordingly to reduce the pollution to the environment. [0003] At present, in sewage treatment, for high COD (Chemical Oxygen Demand; Chemical Oxygen Demand) wastewater, high BOD (Biochemical Oxygen Demand; Biochemical Oxygen Demand) wastewater, drug treatment is generally used to make drugs react with wastewater to achieve the purpose of purifying sewage. . Using the above method, although the sewage can be purified to a certain extent, it is easy to cause serious secondary pol...
