River small buoy multi parameter water quality monitoring equipment

  Remote monitoring system for river water quality (buoy station + remote monitoring integration scheme)
1、 Project overview
1
Basic introduction of automatic water quality monitoring station
Buoy type online water quality monitoring station is a set of economical water quality monitoring data acquisition platform, which takes buoy as the carrier and integrates telemetry terminal, water quality monitoring sensor, Power supply system and anchoring system are used for in-situ online monitoring and early warning of water quality of lakes, reservoirs, rivers and other water bodies
The system has the characteristics of automatic continuous online monitoring and early warning, self-cleaning, wireless data transmission, no reagent, unattended and so on
It is very suitable for building an online monitoring and early warning system of water resources

It is mainly used to continuously and automatically monitor the water quality changes of the measured water body, objectively record the water quality conditions, and timely find the abnormal changes of water quality, so as to realize the prediction of water pollution in the water area or downstream, study the law of water diffusion and self purification, so as to master the water quality and pollutant flux and prevent water pollution accidents, The purpose of providing technical services for environmental protection management or other competent departments

Project plan, evaluation or suggestion
Automatic monitoring equipment for river surface water quality is the key task of water resources protection in the construction plan and one of the most important means to prevent regional water pollution
Through the automatic on-line monitoring instrument for unattended real-time monitoring of an area, and the use of modern information technology for data acquisition, transmission and storage, we can timely and accurately grasp the water quality and water level status and dynamic change trend of the water area in this area
The project reflects the scientific and modern technical means of water environment monitoring, and is of great significance to the environmental protection decision-making department and business competent department to make timely and effective water pollution prevention and management

  The main contents of the proposed automatic water quality and level monitoring equipment project are: Real time online analysis and monitoring of five water quality parameters (temperature, pH, dissolved oxygen, turbidity and conductivity)
2、 Basic construction tasks and requirements of water quality automatic monitoring system

Site construction content
It involves the construction tasks of the site's measurement and control system
Under the premise of grasping the basic principles of practicality, advanced nature, openness, security and economy, some functions need to be chosen, and some functions should be strengthened or even some new functions should be properly expanded
This is the value and significance of item company

  Buoy type (as shown in the figure below)
 
 
  At present, the water quality monitoring construction project is an important content to improve the management level of relevant departments
On the premise of safety and practicability, combined with the task requirements and objective conditions of the project, we suggest that the buoy water quality monitoring station should be the main solution of the project

Scheme implementation plan
 
1）  Select the water quality factors to be monitored in real time
After preliminary discussion with the construction party, the contents of phase I project of water quality monitoring parameters are preliminarily determined as follows:
Probe type temperature, dissolved oxygen, conductivity, turbidity and pH sensors carried on the buoy;
2）  Select buoy type on-site water quality monitoring station
  Buoy type water quality monitoring station, equipment configuration and function description of each station are as follows:
A dissolved oxygen monitor: molecular oxygen dissolved in water is called dissolved oxygen
Dissolved oxygen value is a basis for studying the self purification ability of water
The dissolved oxygen in the water is consumed, and it takes a short time to return to the initial state, indicating that the self purification capacity of the water body is strong, or the water pollution is not serious
Otherwise, it means that the water pollution is serious, the self purification ability is weak, and even the self purification ability is lost
Therefore, this item is an important index to measure the self purification capacity of No
5 pool in Fenhe scenic spot

B conductivity monitor: it is a measurement value indicating the strength of the material's ability to transmit current
The better the conductivity of water, the greater the conductivity value, and the greater the total dissolved solids value of water

Generally speaking, the total soluble solid value represents the impurity content of dissolved matter in water
The greater the value, the greater the impurity content in water
On the contrary, the impurity content is small
The purer the water, the lower the conductivity
Therefore, conductivity is a measure of the purity of pool 5 in Fenhe scenic spot

C turbidity monitor: turbidity is a measure of the transparency of water
Water with high turbidity will appear turbid or opaque; Water with low turbidity is clear and transparent
Turbidity is caused by small particles, such as silt, clay, microorganisms and organic matter
It is a measure of the scattering of light by these particles
It is also a direct measure of the transparency of the water body of No

D pH monitor: hydrogen ion activity index is a scale of hydrogen ion activity in solution, that is, the measurement standard of solution pH in the general sense
Important parameters for evaluating water quality
PH is often closely related to some analysis items, so pH is an essential monitoring item
