Problems solved by technology

[0004] ①Reduce the sewage treatment capacity of MBR
[0005] ②Increased investment cost and operating cost
Water permeability cannot be directly measured, and water plants generally use calculation methods to estimate the water permeability, which leads to a serious hysteresis in the water permeability and cannot achieve accurate online prediction of membrane fouling

Abstract

The invention relates to an intelligent detection method for MBR membrane water permeability based on a deep belief network. The detection method includes: (1) determining target variables and characteristic variables; (2) designing a soft measurement model for membrane water permeability, and using DBN to establish and predict membrane water permeability Soft measurement model of water permeability: (3) Correct the established soft measurement model of effluent water permeability, and obtain the simulation error curve and prediction result map; (4) Water permeability prediction. Based on DBN, a soft measurement model of membrane water permeability is established, which reduces the computational complexity of water permeability, realizes accurate online measurement and real-time correction of water permeability, and provides an effective method for predicting the fouling state of membranes in sewage treatment. , improve the working efficiency and economic benefits of the MBR membrane sewage treatment process.

Description

technical field [0001] The invention relates to the technical field of on-line detection of sewage treatment water quality, in particular to an intelligent detection method for water permeability of MBR membranes based on a deep belief network. Background technique [0002] In recent years, the number and sewage treatment capacity of my country's sewage treatment plants have gradually increased. The growth rate of sewage treatment capacity is higher than that of sewage treatment capacity, and the operating load rate has also increased rapidly, indicating that the demand for sewage treatment has increased rapidly. At the same time, the national development plan proposes to study and promote low-energy, high-efficiency sewage treatment technologies. The average annual growth rate of the total output value of the membrane industry is greater than or equal to 20%, and it is predicted to reach 200-250 billion yuan by 2020. MBR membrane plays an important role in sewage treatment,...
