Abstract
Description
technical field
[0001] The invention relates to a method for predicting water quality indexes, in particular to a method for predicting urban sewage water quality indexes. Background technique
[0002] The determination of urban sewage design water quality indicators is the prerequisite for the selection of process flow of sewage treatment plants, and is closely related to the construction costs, operation management methods and operating costs of sewage treatment plants. However, in many cities, especially in southern cities with high groundwater levels, the influent concentration of sewage plants is relatively low, and the amount of sewage varies greatly. As a result, sewage treatment plants designed according to conventional design water quality and quantity indicators have long been in aeration tank sludge load. Low oxygenation, excessive oxygenation, and poor growth of activated sludge not only bring inconvenience to operation management, but also increase operating cos...
