摘要： PROBLEM TO BE SOLVED: To provide a waste water treating system and its method capable of neutralizing carbon dioxide in waste gas while suppressing the scatting of the waste to be treated even if the waste gas from a cogeneration of large gas flow rate is used. SOLUTION: In the waste water treating system in which the waste water is subjected to neutralizing treatment by allowing the waste water discharged from a boiler to make it contact with the waste gas discharged from the boiler, the system is provided with a waste water receiving tank 4 for receiving and storing the waste water, a spray nozzle 8 for returning the waste water stored in the waste water receiving tank 4 to the waste water receiving tank 4 while sprinkling the water to the discharged waste gas, a circulation pump 5 for circulating the waste water between the spray nozzle 8 and the waste water receiving tank 4, a pH meter 6 for measuring the neutralization degree of the waste water under circulation and a solenoid valve 7 for discharging the waste water under circulation when the neutralization degree of the waste water becomes within discharging range.

摘要： PROBLEM TO BE SOLVED: To obtain highly pure water easily at a low cost by simple equipment by holding stable purity over a long period of time. SOLUTION: In a pure water making apparatus, a cathode chamber 4 having a cathode 3 and an anode chamber 6 having an anode 5 are formed in opposed relationship. Desalting chambers 9 and concn. chambers 10 are successively formed by cation exchange membranes 7 and anion exchange membranes 8 alternately arranged between the cathode chamber 4 and the anode chamber 5. While voltage is applied across the cathode 3 and the anode 5, water to be treated is allowed to flow to the desalting chambers 9 and water to be treated is allowed to flow to the concn. chambers 10 as conc. water. Water to be treated is allowed to flow to the anode chamber 6 as electrode water and the electrode water passed through the anode chamber 6 to become acidic is allowed to flow to the cathode chamber 4. Ions in water to be treated passed through the desalting chambers 9 move to the concn. chambers 10 to make deionized pure water.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating an open circulating cooling water system capable of preventing a waste of a supply water, saving a water using amount and stabilizing water quality of a circulating cooling water. SOLUTION: The method for treating an open circulating cooling water system comprises the steps of taking out a part of the circulating cooling water A from the open circulating cooling water system 19, filtering the taken-out cooling water by using a filter 41, and then returning the filtered water to the original open circulating cooling water system 19. The method further comprises the steps of back-washing the filter 41 at a time of predicting clogging or generating the clogging or at the time in which electrical conductivity of the cooling water A becomes a preset value or more in such a manner that as a back washing water, the cooling water A is used, draining the back washing water out of the system 19, and supplying a supply water B having lower electrical conductivity than that of the set value corresponding to the back washing drain discharged out of the system 19.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating open circulating cooling water, in which an excess of new water supply is prevented, the used amount of water can be saved, and the quality of circulating cooling water can be made stable. SOLUTION: A portion of the circulating cooling water A is taken out of the open circulating cooling water system 19, and then, the taken circulating cooling water A is filtered using a filter 41 and returned to the open circulating cooling water system 19. When the filter 41 is subjected to reverse washing, the portion of the circulating cooling water A taken out of the open circulating cooling water system 19 is filtered using a part of the effective filtration area of the filter 41 and returned to the open circulating cooling water system 19. The reverse washing is carried out at other effective filtration area of the filter 41 using other portion of the circulating cooling water A taken out of the open circulating cooling water system 19, and exhausted water generated at the time of the reverse washing is discharged to the outside of the open circulating cooling water system 19.
