Description

An automatic dosing system

technical field

The utility model relates to the technical field of automatic dosing devices, in particular to an automatic dosing system.

Background technique

In the water treatment process of environmental engineering, it is often necessary to add chemicals to it to achieve water purification. The purpose of adding chemicals is pH neutralization, chemical precipitation, chemical reduction, etc. If the dosage is too large, it will inevitably cause waste of chemicals, or even Affect the effect of wastewater treatment. For some situations where the requirements for chemical dosing are strict, imprecise chemical dosing will inevitably lead to serious consequences. For example, methanogenic bacteria in anaerobic reactions need a pH condition of 6.8-7.2, and methanogenic bacteria cannot reach pH conditions beyond this range. Normal survival will lead to acidification of the anaerobic system, seriously affecting the effluent effect, and for example, in the removal of trivalent chromium with alkali, the removal of trivalent chromium is not complete when the amount of alkali is added, and the complex of trivalent chromium is still formed if the alkali is added too much. Staying in the water phase, the precise control of medicament dosing is not only a problem of waste of medicament, but more importantly, a problem of the effect on wastewater treatment. Therefore, the control of system dosing is very important. Whether the automation and accuracy of dosing can be realized is the key to the excellent effect of wastewater treatment and the level of operating costs.

At present, the existing dosing system only uses metering pumps for dosing, and the dosing amount is a fixed value, which is generally suitable for operating conditions with stable water quality and quantity, and cannot be adjusted in real time according to changes in water quality and water quantity. At the same time, due to the fixed dosage, Inaccurate control of the final control indicators of the system can easily lead to too little or too much medicament dosage. The actual water quality and quantity fluctuate greatly, and there is a big difference between the fixed dosage and the actual wastewater demand for chemicals. The current dosage method will inevitably lead to waste of chemicals or poor treatment effect. The automatic dosing system that adjusts the dosing amount in time according to the water volume is very necessary to realize the precise control of the system dosing amount.
