TECHNICAL FIELD
[0001] The utility model relates to water treatment field, concretely is carbon dioxide intelligence adds equipment. BACKGROUND
[0002] In the water source transportation and storage process, a variety of factors can cause the pH value of water body to rise. When the South-to-North Water Diversion Project is in operation, the alkaline components in the open channel cement material can be precipitated after long-term soaking, causing the pH value of water to rise. The pH value of water body can also rise due to the consumption of carbon dioxide in water by the growth of algae in reservoirs. The increase of pH value of raw water can have many adverse effects on water treatment processes and water quality. Most surface water plants use aluminum-based coagulants. When the pH value of raw water is greater than 8.0, the solubility of aluminum increases under weak alkaline conditions, which can affect the removal efficiency of aluminum and cause the aluminum content of finished water to exceed the standard. Excessive absorption of aluminum can harm the nervous system and kidney function of the human body. In addition, abnormal pH value can also affect the disinfection effect and the amount of disinfection by-products generated, so carbon dioxide intelligent adding equipment is needed.
[0003] The existing equipment uses HCl to adjust the pH value during operation. Since hydrochloric acid is volatile, it can be dangerous during storage. The strong acidity of hydrochloric acid can affect the equipment in the treatment process section after being added to the section. The chloride ion in the hydrochloric acid solution is difficult to remove through other process sections after entering the water. If the human body uses drinking water with a high concentration of chloride ions, it can cause acid-base imbalance, electrolyte disorder, nerve and muscle function damage, increased kidney burden, and respiratory difficulties. By increasing the PAC dosage to reduce the pH of the water body, many water plants do not have a pH adjustment system in the raw water section. Since PAC is acidic when dissolved in water, they increase the PAC dosage to reduce the pH of the raw water in the water plant. This can cause the residual aluminum in the finished water to be too high, which can harm the human body. Therefore, there is an urgent need for carbon dioxide intelligent adding equipment. SUMMARY
[0004] Based on this, the utility model discloses the purpose is to provide carbon dioxide intelligent dosing equipment to solve the equipment of existing in use, adopt Hcl to carry out the adjustment of PH: because hydrochloric acid has volatility, is easy to cause the danger in the storage process, the acidity of hydrochloric acid is stronger, and after adding to the processing process section, can cause the influence to the equipment of this process section, the chloride ion is in the hydrochloric acid solution, and after entering water, too much chloride ion is difficult to remove through other process section, if the human body quotes the drinking water of too high concentration chloride ion, can cause acid-base balance disorder, electrolyte disorder, nerve and muscle function damage, kidney burden aggravation, breathing difficulty etc. Harm, through the addition of PAC's dosing quantity to reduce the PH of water body, at present many waterworks raw water section does not have the system of adjusting PH, because PAC is acid after dissolving in water, so they reach the purpose of reducing the PH of waterworks raw water by increasing the dosing quantity of PAC, which leads to the problem of high residual aluminum of finished water, which is harmful to human body.
