Method for optimizing structure of integrated domestic sewage treatment device

Abstract

The invention provides a method for optimizing a structure of an integrated domestic sewage treatment device, and the method can be used for improving the decontamination effect. The method comprises the following steps of: S1, generating a grid file corresponding to the integrated domestic sewage treatment device according to a preset simulation condition; S2, carrying out iterative solution on the generated grid file according to a preset solution parameter so as to simulate a flow state in the device and then obtain cloud charts and vector diagrams of a speed and a pressure under the current simulation condition; S3, setting a plurality of groups of different simulation conditions, and repeating the steps S1 and S2 to obtain the cloud charts and vector diagrams of speeds and pressures under different simulation conditions; and S4, analyzing and comparing the obtained cloud charts and vector diagrams of the speeds and pressures under different simulation conditions, and selecting a simulation condition corresponding to an optimum flow state mixing effect, wherein flow state mixing effect is represented by the cloud charts and vector diagrams of the speeds and pressures. The method provided by the invention is suitable for the technical field of environmental engineering.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a method for optimizing the structure of an integrated domestic sewage treatment device. Background technique [0002] In the past 20 years, although my country's sewage treatment plants have been continuously built and the sewage treatment rate has continued to increase, they are mainly concentrated in cities. Most of the rural sewage has not been treated, and the proportion of rural sewage discharge in the total sewage discharge is also increasing. bigger. According to the National Environmental Quality Bulletin, drinking water sources and surface water in 798 rural environmental quality pilot villages across the country have been polluted to varying degrees. The random discharge of sewage in rural areas not only causes damage to the environment, but also pollutes the rivers that flow through it. Ditches, ponds, and reservoirs in rural areas have become quite ...
