Abstract

PURPOSE: To enable uniform preparation of a sludge treating chemical agent by performing automatic preparation according to sequence control in preparation of the agent by charging a sodium silicate type chemical agent into an acidic chemical agent.
CONSTITUTION: When it is detected that there is not a sludge treating chemical agent C liquor (acidic silica sol) in preparation vessel 3 with lower level detector MB, the signal is inputted in controller 12, and first valve V1 is opened to charge an acidic chemical agent A liquor into vessel 3 through injection pipe 4. When A liquor reaches the upper level, upper level detector MA detects that, and according to the signal valve V1 is closed. Simultaneously with the closing second valve V2 is opened, and agitator 8 and constant vol. pump P are actuated to charge a sodium silicate type chemical agent B liquor into vessel 3. Composite electrode 9 performs pH detection, the signal is inputted in controller 12, and when the value reaches a predtermined value, valve V2 is closed, and pump P is stopped. Third valve V3 is then opened to discharge C liquor.
