The all-weather water quality monitoring service platform comprises an automatic analysis module, a detection control module and a remote management module. The automatic analysis module comprises a precise constant flow pump, an ultraviolet lamp, a heater, a quartz digester, and a pump-type control valve. The detection control module comprises a detection portion and a control portion. The detection portion comprises a light source, a light source receiver, a sample detection device and a pump-type control valve which are used for completing the detection of samples collectively. The control portion comprises a PLC programmable logic controller, a master control board, a human-computer interface and a GPRS communication module which are used for completing the control of sample detection results. Data transmission is performed between the remote management module and each site online monitoring apparatus through wireless communication service software. According to the invention, the efficient operation of a circulating water system in the real-time monitoring condition can be ensured, and early warning is performed through the remote management system, so operators can be reminded timely when a failure occurs, so that the hidden failure can be eliminated rapidly. Secondly, the advantage of good economic benefit can be realized.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an all-weather water quality monitoring service platform. Background technique [0002] At present, the water quality control method of industrial circulating water mainly adopts the method of phosphorus water treatment agent to prevent the scaling and corrosion of the pipeline. Even if there is only a thin layer of scale attached to the surface of the circulating water pipe, the scale will greatly affect the heat transfer efficiency. Polyphosphate and phosphoric acid are universal and effective scale inhibitors and corrosion inhibitors. Their stabilizing effect depends on the comprehensive reaction of polyphosphate and phosphoric acid with calcium, magnesium, iron and manganese ions in water. Therefore, control The concentration of corrosion and scale inhibitors in circulating water is very important, while conductivity, PH, ORP, turbidity and other indicators are also ...

AI Technical Summary

Problems solved by technology

[0004] At present, the main detection systems on the market are: (1) Flow proportional dosing system: according to the supplementary water volume of circulating cooling water, corrosion inhibitors and scale inhibitors are added in proportion The structure of the system is relatively simple, and it cannot meet the water quality control requirements of large and medium-sized circulating water. The control precision is low, and the phenomenon of under-addition or over-addition of the agent often occurs, and the waste of the agent is serious.

(2) Flow ratio plus concentration multiple dosing system: This system calculates the concentration multiple based on the ratio of the conductivity of the supplementary water to the conductivity of the circulating water. The structure is complicated, the installation is cumbersome, and it is difficult to maintain. The medicine is adjusted to an artificial estimate, and there will often be under-dosing or over-dosing of the medicine, which is a waste of medicine

(3) Tracer dosing system: Theoretically, this system adds fluorescent agent to the water treatment agent in a certain proportion and mixes it evenly, puts it into the circulating water system, uses a fluorescence detector to detect the fluorescent agent content in the circulating water, and calculates the water treatment value. Drug content, according to the control index, control the amount of dosing, to achieve the purpose of automatic dosing, but the disadvantage of this method is that the half-life of the fluorescent tracer and the water treatment agent are different, which will cause detection errors, and the water treatment system has a cooling tower , there are fillers that will adsorb fluorescent agents and water treatment chemicals, and will also cause measurement errors, making it difficult to truly reflect the real concentration of chemicals in circulating water, and there will often be under-addition or over-addition of chemicals, wasting chemicals

Chemical water treatment agent manufacturers and equipment manufacturers are seriously out of touch, resulting in waste of water quality monitoring data
