Problems solved by technology

[0006] However, the method of single-use UV absorption measurement is very rough and imprecise, and it is also common in the sensor system of single-parameter measurement, which leads to the difference between the measured data and chemical The COD data measured by the method are very close, but in the case of relatively large changes in pollution components, there is a relatively large deviation, which limits the use of this method

Abstract

The invention discloses a multi-parameter integrated COD (Chemical Oxygen Demand) water quality monitoring system comprising a wireless transmission system (2), a monitoring terminal (3) arranged far away from the water area to be monitored and in the monitoring room, and at least one multi-parameter induction terminal (1) that is arranged at the water area to be monitored; each multi-parameter induction terminal (1) is wirelessly connected with the inlet end of the wireless transmission system (2); and the outlet end of the wireless transmission system (2) is wirelessly connected with the monitoring terminal (3). The invention also provides a method which utilizes the monitoring system to carry out the multi-parameter integrated COD water quality monitoring. The method comprises the steps of 1) monitoring the following four parameters of the water area to be monitored by the multi-parameter induction terminal (1): ultrasonic absorption, turbidity, temperature and pH value; 2) transmitting the four parameters to the monitoring terminal (3) through the wireless transmission system (2) by the multi-parameter induction terminal (1); and carrying out the calculation by the monitoring terminal (3).

Description

technical field [0001] The invention relates to a monitoring system for water quality organic matter pollution and a corresponding monitoring method, which can be widely used in the fields of water quality organic matter pollution such as various enterprise sewage discharges, domestic sewage, surface water, and ground water. Background technique [0002] Chemical oxygen demand (COD) is a measurement of the concentration of organic and inorganic oxides in water, reflecting the degree of water pollution by reducing substances, and is an important indicator of water quality evaluation. It is very common for water bodies to be polluted by organic matter, so COD is often used as one of the indicators reflecting the degree of organic matter pollution. [0003] Ultraviolet absorbance (UVA) has been published as a comprehensive indicator of organic pollution for many years. It is a pure physical optical indicator. No chemical reagents are used in the measurement process, and there i...
