example 1

[0027] Example 1: Install near the sewage outlet, monitor and deal with it in time.

[0028] The automatic sampling device can be installed near the sewage outlet to monitor the discharge of sewage and wastewater. Once the water quality parameters exceed the standard, the automatic sampling device will immediately alarm, save the alarm parameter category, measured data, and the time of the overrun event, etc., and send it in the form of SMS Send it to the alarm mobile phone and the environmental protection management server, so that the emission can be stopped in time and corresponding treatment can be made.

example 2

[0029] Example 2: Installed far away from the sewage outlet to monitor water quality and deal with sewage disputes.

[0030] In order to cope with the phenomenon of sneak discharge, the automatic sampling device is installed in the downstream far away from the sewage outlet, but there may be more than one pollution-related enterprise in the upstream, because the sampling decision-making system of the present invention (combination of more than 5 high-sensitivity sensors can make automatic monitoring The sampling device has the performance of high sensitivity and low omission rate, and the five-factor double-level (absolute value + variation) over-standard decision-making system enables the automatic monitoring sampler to have a low misjudgment rate.) It can still monitor water quality parameters reliably and efficiently , once the water quality parameters exceed the standard, the automatic sampling device will immediately alarm and collect water samples, and the real-time data ...

example 3

[0031] Example 3: According to the number of upstream pollution-related enterprises and different pollution indicators, different sensors and corresponding threshold parameter settings can be replaced to meet the monitoring needs of different indicators, and the decision-making algorithm can also be extended to ten factors and double levels.

Abstract

The invention discloses a water pollution monitoring automatic sampling decision making system which comprises an on-line measurement sensor, a pretreatment circuit, a singlechip, a wireless transmission module and a sampling device, wherein the on-line measurement sensor is an on-line monitor sensing system which is composed of a pH value sensor, an electric conductivity sensor, a dissolved oxygen sensor, a cloudiness sensor and a temperature sensor; the on-line monitor sensing system sends multiple paths of collected signals to the signal input end of the singlechip with an absolute value and relative value algorithm for five water quality general parameters (the pH value, the electric conductivity, the dissolved oxygen, the cloudiness and the temperature) through the pretreatment circuit; and the singlechip and the wireless transmission module realize communication linkage through an interface circuit, and the control output end of the singlechip is connected with a drive circuit of the sampling device through the interface circuit. The water pollution monitoring automatic sampling decision making system provided by the invention can be used for realizing that a water quality sampler can monitor multinomial water-quality indexes on same monitoring point, and has the advantages that the structure is simple, the using cost is low, the working flow of a monitoring and collecting system is more reasonable, and the like.

Description

technical field [0001] The invention relates to water quality monitoring, waste water discharge supervision technology and equipment thereof. In particular, it relates to an automatic sampling device and a decision-making system used in a supervision system for illegal discharge of sewage and waste water. Background technique [0002] Application of the existing online water quality monitoring system: For example, the water quality online monitoring system of urban sewage treatment plants is composed of on-site monitoring stations of sewage treatment plants, monitoring centers, management centers and communication network systems. [0003] Monitoring stations are generally set up near the water inlet and outlet of each phase of the project. Generally, each analytical instrument only analyzes one water quality indicator, and needs to be equipped with a water quality sampler. When multiple water quality indicators need to be monitored at the same monitoring point, it needs to ...
