Embodiment Construction

[0094] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.

[0095] The inventor finds through investigation and research that the present invention discloses a method for controlling dosing in a water plant, such as figure 1 As shown, a schematic flow diagram disclosed in the embodiment of the present invention is provided, including the following steps:

[0096] S1. Draw the first dosing curve with the original turbidity of the water source as the abscissa and the first dosage as the ordinate, and draw the first dosing curve with the original turbidity of the water source as the abscissa and the weighed sediment mass as the ordinate A row of mud working curves;

[0097] S2. Draw the second dosing curve with the water source flow as the abscissa and the second dosa...

Abstract

The invention discloses a dosing control method and system for a water plant. The dosing control method comprises the following steps: drawing a first dosing working curve taking the original turbidity of a water source as an abscissa and taking a first dosage as an ordinate, and drawing a first sludge discharge working curve taking the original turbidity of the water source as an abscissa and taking the mass of weighed sediment as an ordinate; drawing a second dosing working curve taking the water source flow as an abscissa and the second dosage as an ordinate; controlling dosing equipment inthe water plant to perform dosing operation by utilizing the first dosing working curve and the second dosing working curve; judging whether alarm operation is carried out or not in real time by thepre-warning turbidity meter while dosing, and calculating the dosage of the dispensing pool needing to be increased; and enabling the sludge discharging equipment to judge whether sludge discharging operation is carried out or not. By simulating the pool treatment process, each water plant can draw a curve according to the actual situation of the water plant, the turbidity behind the sedimentationtank is controlled within the target turbidity, the water quality safety is ensured, and the use amount of a water purifying agent is reduced.

Description

technical field [0001] The invention relates to a water plant dosing control method and system. Background technique [0002] Now common water plants generally adopt the technology of combining international standards and using general calculation formulas to calculate the dosage, but the data given by the international standards are very rough, and there is no way to make detailed regulations, such as rapid stirring. The international standard stipulates that rapid stirring is 10s-30s is 550 rpm. This is because the actual situation of each water plant is different, and the dosage is also different in different situations. Each water plant has a pool size, pool structure, source water conditions, PH and water temperature. They are different. For example, the inclined tube sedimentation tank saves more medicine than the advection tank. It is obviously unscientific to only use a general calculation formula to calculate the dosage without considering the actual situation. And...
