Carbon source intelligent dosing system and application thereof in sewage treatment

Abstract

The invention belongs to sewage treatment devices and application thereof and particularly discloses a carbon source intelligent dosing system and the application thereof in sewage treatment. Ac control device is adopted to collect fed water and discharged water of a denitrification tank, and real-time data including nitric nitrogen, nitrite nitrogen, flows, COD (Chemical Oxygen Demand) and ORP (Oxido Reduction Potential) of the denitrification tank, a total carbon source dosing amount is calculated and verified according to real-time detection data, and a pumping device which is connected with a carbon source storage tank is controlled according to the verified total carbon source dosing amount to achieve sectional precise dosing of a carbon source into the denitrification tank. By adopting the system, the technical problem, in the prior art, that a carbon source dosing amount cannot be precisely controlled is effectively solved, and the system has the advantages that sectional precise control on carbon source dosing is effectively achieved, automatic control is easily achieved, convenience can be brought to mounting and maintenance, and the like.

Description

technical field [0001] The invention belongs to a sewage treatment device and its application, in particular to a carbon source intelligent dosing system and its application in sewage treatment. Background technique [0002] Denitrification reaction is an important link in the removal of nitrogen in the biological treatment process. In the denitrification of sewage biological treatment, the ammonified organic nitrogen is converted into ammonia nitrogen, and ammonia nitrogen generates nitrate nitrogen and nitrite nitrogen under the action of nitrifying bacteria. Under the action of denitrifying bacteria, the two kinds of nitrogen use organic matter as electron acceptors in an anoxic environment, and finally become nitrogen gas and release it into the air. Taking methanol as an example, the reaction formula is as follows: [0003] [0004] At present, in order to ensure the normal progress of the denitrification reaction and meet the increasingly stringent requirements for...

Problems solved by technology

"The main problem of this existing technology is that it is only suitable for denitrification of closed water bodies, but it is not suitable for most water plants with continuous water inflow and outflow. Pulse dosing is only suitable for a small amount of dosing. When the amount of water to be treated is large Difficult to satisfy
