Problems solved by technology

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 costs in vain

Embodiment Construction

[0019] The invention establishes a predictive formula for the annual average concentration of pollutants in urban sewage, which quantitatively includes variables such as the degradation rate of pollutants in septic tanks and pipes, the infiltration of groundwater in sewage pipes, and the like.

[0020] The method provided by the invention can be popularized and applied to southern cities with relatively high groundwater levels. Appropriate monitoring of some data can correct some parameters in the prediction formula, and the method can be used to predict the annual average value and variation range of water quality indicators in specific urban sewage .

[0021] The present invention will be further described below in conjunction with embodiment, but does not limit the present invention.

[0022] The present invention is used for predicting the COD in 2020 of Huangjiahu sewage treatment plant in Wuhan City, and its steps are as follows:

[0023] 1. The amount of urban sewage i...

Abstract

This invention discloses one city polluted water quality prediction method, which comprises the following steps: firstly researching and collection parameters composed of pollution water shop service area design entrance, citizen integral lift water volume, industry total product, citizen life water pollution parameters and underground water volume; then computing each year daily water pollution volume and continuing collection composed of the remove rate, service area manure rate and industry water pollution standard changes.

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...
