Accurate dosing method for tap water treatment

Abstract

The invention discloses an accurate dosing method for tap water treatment. The accurate dosing method comprises the following steps: data preprocessing: performing 0 value, null value and abnormal value processing; through correlation analysis, analyzing a relation between water inlet indexes including water inlet flow, water inlet turbidity, water inlet PH, dosing amount and water outlet turbidity; constructing a linear regression equation of daily average inflow turbidity and daily average dosage; constructing an effluent turbidity prediction model by utilizing a system dynamic equation algorithm; determining dosing effluent turbidity lag time by using a K-L information method; searching an approximate sample in the historical samples according to a Manhattan distance algorithm, and carrying out approximate optimal solution analysis on the dosing amount; and using a simulated annealing algorithm to analyze the optimal solution of the dosing amount optimization. The invention is highin practicability, accurate dosing control in the tap water production process is achieved, economic losses caused by manual saturated dosing are effectively avoided under the condition that the effluent quality is guaranteed, and the device is of great significance.

Description

technical field [0001] The invention relates to the technical field of water affairs, more specifically, a precise dosing method for tap water treatment. Background technique [0002] Coagulation dosing is the core link in the tap water production process, which directly affects the quality of effluent water, and the most important factor affecting the coagulation effect is the dosage of coagulant. [0003] Most of the coagulants currently used are aluminum salts. Studies have shown that excessive concentration of aluminum ions in water will affect human health and have adverse effects on water quality and water delivery systems. On the other hand, the cost of coagulants and chemicals for water purification is the second largest factor in the cost of water production after electricity costs. The amount of coagulant dosage directly affects the cost of water production and even the price of water. Under the premise of ensuring the treatment effect, Saving the consumption of c...
