Flexible sewage treatment working condition control method

Abstract

The invention provides a flexible sewage treatment working condition control method. The method comprises the following steps of: (1) identifying sewage; (2) recommending a process route; (3) monitoring process parameters; (4) meeting the optimal working condition; (5) determining an optimal process route and working conditions; and (6) storing data in a database. According to the method of the invention, the adjustment effect of a flexible working condition is effectively utilized, the sewage treatment process can timely adjust the hydraulic retention time and the working condition along with the change of water quality and water quantity, the removal of organic pollutants and effective nitrogen and phosphorus removal are realized under the condition of different water qualities, the treatment effect is stable, the operation cost is reduced, and the operation management is convenient.

Description

technical field [0001] The present disclosure relates to the field of sewage treatment, in particular to a method and process for controlling working conditions of flexible sewage treatment. Background technique [0002] At present, during the sewage operation of sewage plants, large changes in sewage water quality and water volume have become the norm. Although the working conditions have been adjusted during the operation, it will generally lead to high operating costs, unstable effluent water quality and water volume, and the system has undergone After the impact, it is often difficult to restore the optimal process during normal operation, resulting in a lot of sewage treatment plant upgrading. [0003] In addition, in the design process, the process parameters are often selected in the most unfavorable situation, and the process route is relatively single. When the water quality and quantity change greatly, the selected process and parameters are not suitable for the si...

[0002] At present, during the sewage operation of sewage plants, large changes in sewage water quality and water volume have become the norm. Although the working conditions have been adjusted during the operation, it will generally lead to high operating costs, unstable effluent water quality and water volume, and the system has undergone After the impact, it is often difficult to restore the optimal process during normal operation, resulting in many sewage plant renovations and upgrades

[0003] In addition, in the design process, the process parameters are often selected in the most unfavorable situation, and the process route is relatively single. When the water quality and quantity change greatly, the selected process and parameters are not suitable for the situation after the water quality changes. Although the operating conditions can be adjusted, but It cannot fundamentally solve the shortcomings of the process, and often meets the process requirements by adding chemicals, but it leads to a significant increase in costs, usually because the quality of the effluent water does not meet the design requirements
