Abstract

The invention discloses a novel carbon source feeding optimization control device and method. According to the device, a denitrification aeration biological fluidization tank comprises a first reaction zone, a second reaction zone, a third reaction zone and a fourth reaction zone which are communicated in sequence; an online electromagnetic flowmeter and a first online total nitrogen instrument are arranged at the inlet of the first reaction zone; a second online total nitrogen instrument is arranged at the outlet of the fourth reaction zone; the outlet of a carbon source storage tank is communicated with the inlet of a first carbon source feeding pump and the inlet of a second carbon source feeding pump; the outlet of the first carbon source feeding pump is communicated with the chemicalfeeding port of the first reaction zone; and the outlet of the second carbon source feeding pump is communicated with the chemical feeding port of the third reaction zone. According to the invention,the device and the method can realize optimal control of carbon source feeding of the denitrification aeration biological fluidization tank.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a novel carbon source dosing optimization control device and method. Background technique [0002] Due to the relatively low C / N ratio of most urban sewage and industrial wastewater in my country, in order to make the total nitrogen of the treated effluent reach the standard, it is necessary to add methanol, acetic acid, sodium acetate, glucose and other external carbon sources in the denitrification stage of the biological denitrification process. Commonly used biological denitrification processes include A / O, A / A / O and oxidation ditch processes, as well as denitrification biological filter and aerated biological fluidization tank processes commonly used in wastewater upgrading and advanced treatment stages. Theoretically, the addition of carbon sources can be calculated by the content of nitrate nitrogen and nitrite nitrogen in the influent. For example, denitrification ...
