Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering supervision data management, and particularly relates to an engineering supervision platform data management system and method for pollution treatment. BACKGROUND

[0002] The water purification plant is used for treating urban and domestic sewage through a series of physical, biological and chemical purification processes, removing harmful pollutants and impurities in the sewage, so that the water treated by the water purification plant meets the national or local discharge regulations. Therefore, a large amount of data is generated at each link in the process of purifying water quality in the water purification plant. The data is widely distributed and different from each other. The engineering supervision platform can realize data interconnection of each link in the water purification plant. Management personnel can real-time view the data related to each link in the water purification process through a computer or a mobile phone and the like, thereby eliminating the information silos in the water purification plant and realizing visual supervision of the water purification plant, and greatly improving the management efficiency and collaborative ability.

[0003] The water purification plant adds corresponding reagents to the water during the treatment of sewage. The reagents not only can quickly remove impurities in the water, but also can adjust the pH value and microbial activity in the water, kill pathogenic bacteria and viruses in the water, and ensure the safety of the discharged water environment. Therefore, the dosage of the reagents in the water is particularly important. The traditional method is to judge the adding effect of the reagents according to the real-time collected data of the water. However, in the actual process, the influence of the reagents on the water quality has a time delay effect. The reagents will affect the water quality after a period of reaction. Moreover, the types of the added reagents are not single. Different reagents have different delay effects on the water quality. Even under specific water quality, the reagents can affect the water quality indexes adjusted by other reagents. This makes the operator unable to grasp the actual effect of the reagent adding on the water quality, which easily causes the operation behavior of the operator to lag. Not only will this lead to over-dosage of the reagents, resulting in waste of the reagents and increase of the operation cost, but also will seriously affect the water quality, causing the water pollutant content to exceed the standard after treatment in the water purification plant, the biological system to collapse, and the environment to be harmed. SUMMARY

[0004] The present application aims to provide an engineering supervision platform data management system and method for pollution treatment to solve the problems in the prior art.

[0005] To achieve the above object, the present application provides the following technical scheme: an engineering supervision platform data management method for pollution treatment, the method comprising: Step S1: Obtain the water purification process involving reagent addition in the constructed engineering supervision platform, obtain the historical water quality monitoring records and historical reagent addition records of the water purification process, analyze the influence of the reagent on the water quality in the water purification process within a certain time length, and obtain the delay time data of the reagent; Step S2: According to the delay time data, obtain the target water quality set of the reagent, according to the target water quality set of different reagents in the water purification process, analyze the influence of the reagent on the target water quality index of other reagents within different numerical ranges of different water quality indexes, and obtain the water quality range influence data; Step S3: Monitor the water quality of the water to be treated in the water purification process in the current period to obtain initial water quality data, obtain target water quality data from the engineering supervision platform, evaluate the reference value of different elements in the target water quality set of the reagent to the water quality purification in the water purification process in the current period, and obtain the reference water quality set of the reagent; Step S4: According to the reference water quality set of different reagents in the water purification process and the water quality range influence data, analyze the influence of different reagents in the water purification process on the water purification effect under different dosages, obtain the reagent addition data of the water purification process, and send the reagent addition data to the management personnel of the water quality purification plant through the engineering supervision platform.

By obtaining the delay time of the medicament on each target water quality index, the effect of the target water quality index of the medicament on the water quality can be obtained, so that a real connection between the medicament addition amount and the target water quality index is established, and a data basis for subsequent matching of the medicament addition and the water to be treated is provided.
