Abstract

The invention belongs to the technical field of sewage treatment and particularly relates to a reinforcing system for reducing nitrate nitrogen concentration in sewage. The reinforcing system consists of a reaction tank and an aquatic plant recovery tank and is characterized in that the reaction tank consists of a contact area and a reaction area; the aquatic plant recovery tank consists of a recovery tank front end and a recovery tank rear end; and the reaction tank and the aquatic plant recovery tank, the contact area and the reaction area and the recovery tank front end and the recovery tank rear end are all spaced by a bank respectively. In the invention, by adding a carbon source into sewage, the removal rate of total nitrogen and total phosphorus in sewage is increased; and moreover, the design is reasonable and skillful, the cost is low, the raw materials are easily available, and environmental pollution is avoided. The system provided by the invention realizes a good treatment effect on the nitrate nitrogen in sewage and can reduce the nitrate nitrogen concentration in sewage to the greatest degree.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an intensified system for reducing the concentration of nitrate nitrogen in sewage. Background technique [0002] During the operation of the existing water purification plants, during the rainy season, the influent concentration index of sewage is often low, and some indicators are even close to the effluent standard. Insufficient carbon source in the sewage leads to low removal efficiency of total nitrogen and total phosphorus in the effluent, and also causes high nitrate nitrogen in the effluent, as well as pollution with low nitrate nitrogen concentration. Contents of the invention [0003] The object of the present invention is to provide an enhanced system for reducing the concentration of nitrate nitrogen in sewage in order to solve the deficiencies of the prior art. [0004] The present invention is achieved through the following technical solution...
