Water quality safety early warning decision making system

Abstract

The invention provides a water quality safety early warning decision making system. The system is a full-process complete system formed by an on-line monitoring base station layer, a server layer and a water quality safety early warning platform layer. On the basis of the on-line monitoring base station, the server layer serves as a support, and a water quality safety early warning platform serves as a core. The on-line monitoring base station comprises a water inlet unit, a water quality on-line monitoring unit, a pump station operation monitoring unit, an automatic control unit and a remote transmission unit. The water quality safety early warning platform comprises the eight service modules of station measuring information management, water quality data management, statistics and analysis management, operation alarm management, water quality safety early warning and information issuing management. The system can achieve the multiple functions of pipeline running water quality and amount on-line monitoring, remote transmission, data storing, real-time issuing, water quality early warning and remote decision making in rainfall events of a drainage system. Supports can be provided for optimization operation of a city drainage pump station, and decision making bases can be provided for a win-win scheduling model of flood prevention safety and water quality safety of the drainage system.

Description

technical field [0001] The invention relates to the field of water environment and water safety, in particular to a water quality safety early warning decision-making system. Background technique [0002] The urban drainage system undertakes the collection, transportation, treatment and discharge of urban sewage and rainwater. Urban sewage includes domestic sewage and industrial wastewater discharged into urban drainage pipes, mainly from point sources, and can be effectively treated by strengthening collection, transportation and treatment. However, for the rainfall runoff caused by rainfall, the focus of attention in the past has been mainly on ensuring urban water security, which is reflected in the timely elimination of urban runoff from heavy rains to prevent urban waterlogging. However, the urban runoff of heavy rain, especially the runoff formed in the early stage of rainfall, is directly discharged into the water body, which will cause great pollution to the water e...

Problems solved by technology

[0005] Since the 1990s, the online water quality monitoring system with the online water quality monitoring instrument as the core, integrated automatic control technology and wireless communication technology has been developed, and the online water quality monitoring and industrial wastewater quality monitoring in major cities and key river basins in the country have been developed. , Water quality monitoring of inflow and outflow of sewage treatment plants, water quality monitoring of inflow and outflow of water purification plants, and process control of drinking water treatment have been widely used in many fields, but the application of online monitoring of initial rainwater quality is not yet common

There are two problems in obtaining the initial rainwater quality with the currently widely used on-line monitoring instruments: First, most of the currently widely used on-line monitoring instruments are suction-type, which are composed of multi-differentiated flow path systems, with many parts and components involved. There are many types of solutions and strong corrosiveness, resulting in many dead ends, difficult to clean, and frequent blockage and corrosion

The use of this single alarm mode cannot meet the requirements of "concentration and discharge" in the storage tank of the drainage pumping station, nor can it realize the win-win dispatch mode of flood control and emission reduction

[0007] Therefore, the currently widely used online monitoring system and water quality early warning mechanism are difficult to meet the needs of rapid monitoring of initial rainwater quality data and early warning of water quality safety.
