Description

Technical Field

[0001] The present invention belongs to the technical field of port sewage treatment analysis, and relates to an intelligent online analysis and evaluation system for port sewage treatment project construction based on the Internet of Things. Technical Background

[0002] With the increasing frequency of port trade and the continuous expansion of port operations, the discharge of domestic sewage and operational wastewater has increased explosively, and the pollution of marine water bodies has become more serious. In order to protect the ecological environment of the ocean and improve the standardization of port sewage discharge, it is necessary to control the sewage discharge of ports.

[0003] At present, the treatment of port sewage mainly focuses on the water quality analysis of the sewage discharge corresponding to the port sewage discharge outlet. Through the treatment analysis based on the discharged water quality, it is obvious that the current analysis of port sewage treatment projects still has the following deficiencies:

[0004] 1. Port wastewater discharge is often collected through branch pipes and then fed into the main pipe, which then discharges to the sewage treatment center for further discharge. Currently, water quality monitoring is performed only at the discharge outlet, which cannot reflect the water quality status and discharge compliance status of each sewage discharge link. The treatment effect is poor, and it also fails to highlight the key treatment directions and contents of port wastewater.

[0005] 2. Currently, water quality analysis is only conducted on the sewage discharge corresponding to the port sewage outfall, without analyzing the associated discharge areas corresponding to each discharge branch. This makes it impossible to display the sewage discharge status of each port area, and thus cannot provide a reliable basis and clear goals for sewage discharge management in each port area.

[0006] 3. Currently, only sewage from the port sewage outlet is monitored, which cannot reflect the discharge status of each sewage outlet, and thus cannot improve the timeliness of handling the blockage problem of sewage discharge branch pipes, and cannot reduce the safety hazards of sewage discharge. Summary of the Invention

[0007] In view of this, in order to solve the problems raised in the above background technology, an intelligent online analysis and evaluation system for port sewage treatment project construction based on the Internet of Things is proposed.
