Document Type and Number:
WIPO Patent Application WO/2023/165001
Kind Code:
A1
Abstract:
Disclosed are a composite sewage denitrification process device and an operation parameter optimization method. In the composite sewage denitrification process device having a built-in electrode biological carrier, a Box-Behnken model is used to design an orthogonal experiment, the carbon-nitrogen ratio, the hydraulic retention time, and the sludge volume fraction are selected as influence factors, the nitrate nitrogen removal rate, the COD removal efficiency, and the electrode carrier area denitrification contribution ratio are selected as response variables, an orthogonal experiment result is analyzed by using the response surface methodology, and a mathematical model between the influence factors and the response variables is established. According to the present invention, an optimization and control scheme for a process operation condition is obtained by using the response surface methodology, the efficiency of a process under different operation conditions can be predicted, and the present invention has the advantages of reducing the experimental workload and shortening the process operation time.
