Method for biologically monitoring and early warning water quality of water supply company

Abstract

The invention relates to a method for biological monitoring and early warning of water quality of a water supply company. The method comprises the following steps that water is taken from a water taking well (9) through a water taking pipe (10), and a biological monitoring and sampling system (4) is connected with a sample injection pipe (11); 2, water enters the biological monitoring sampling system (4) through a thermostat (12); 3, a high-definition camera (16) is arranged relative to the biological monitoring automatic sampling system (4), and is connected with a computer (19), and movementconditions of planktons (17) are automatically tracked and recorded through the high-definition camera; 4, whether the water quality is good is judged according to plankton indication information; and 5, if the plankton motion trail is abnormal, the sample points are immediately stored, and physicochemical index detection and analysis is performed. By means of continuous real-time biological monitoring and real-time online water quality monitoring, short-term and sudden environmental pollution accidents can be warned in time, and real-time analysis data are provided for water supply safety.

Description

technical field [0001] The invention belongs to the technical field of water treatment and monitoring, in particular to a method for biological monitoring and early warning of water quality in water supply companies. Background technique [0002] In my country's urban and rural water supply system, the water supply sources are mainly surface water and groundwater in lakes and reservoirs, and the water treatment processes are mainly membrane treatment technology, chlorine disinfection treatment technology, etc. In terms of water quality monitoring, the raw water quality is mainly based on physical and chemical testing and analysis in accordance with water quality monitoring standards such as "Groundwater Quality Standards" (GB / T14808-2017) and "Surface Water Environmental Quality Standards" (GB 3838-2002). Water quality monitoring is mainly carried out in accordance with the detection indicators of the "Drinking Water Sanitation Standard" (GB5749-2006). According to the surv...

Problems solved by technology

[0003] Based on the above problems, this time a method of indicating the water quality by the change of plankton signs is proposed. Before the raw water is treated and supplied to water users, plankton indicators are installed, and the water quality changes are analyzed in real time according to the changes of plankton signs. Through continuous Real-time biological monitoring and real-time online monitoring of water quality can give early warning to short-term and sudden environmental pollution accidents in time, and provide real-time analysis data for water supply safety, thereby fundamentally solving the data lag problem and high resources caused by physical and chemical detection methods waste problem
