Controlled online stage-wise monitoring method and system of multiple related test items

Abstract

The invention relates to a controlled online stage-wise monitoring method of multiple related test items, which is used in discharge of water flow in the surface water pipe networks such as urban rivers, reservoirs, lakes and the like based on different quality. The method comprises the following steps: firstly, determining the online monitoring items through multiple related probability selection of online test items; and secondly, carrying out stage-wise monitoring according to the determined online monitoring items to realize control of discharge of water flow in the surface water pipe networks based on different quality. The invention has the following beneficial effects: after undergoing controlled online stage-wise monitoring, the online monitoring items obtained by the invention can directly or indirectly ensure the rest water quality items to be monitored (including the items which need chemical reactions under specific conditions and long-time biological culture and can not undergo online monitoring); the invention has the advantages of reasonable and rapid monitoring and low cost; and the invention provides the possibility and basis of being capable of immediately converting variation of the water quality states into an execution instruction for discharge of water flow in the pipe networks based on different quality and can immediately transfer the water quality variation information to the management department to serve as the subsequent original water quality monitoring data.

Description

technical field [0001] The present invention relates to the field of urban rivers, reservoirs, lakes, rain and sewage mixed flow pipe network water flow pollution control, more specifically, relates to a rain and sewage mixed flow pipe network that can be used for water quality discharge in urban rivers, reservoirs, lakes and other surface water A controlled online multi-directional correlation test item classification monitoring method. Background technique [0002] The water quality discharge of urban rainwater and sewage mixed flow pipe network is an effective method to prevent urban sewage from polluting urban rivers, reservoirs and lakes. When the water quality of the pipe network meets the management and functional standards of urban rivers, reservoirs, and lakes, it will be discharged into rivers, reservoirs, and lakes, otherwise it will be discharged into sewage treatment plants. On-line monitoring of water quality to obtain the current water quality item test value...
