METHOD FOR PREVENTING BLOCKAGE OF COLLECTION PIPES IN DRAINAGE COLLECTION FACILITIES

Japanese Patent JP2022172037

A

PURPOSE: To provide a method for preventing blockage of drainage collection pipes in drainage collection facilities, which enables the ionization of salts adhering to blockages to be maintained by using solidified fulvic acid and humic acid, which are produced by soaking an appropriate amount of undecomposed organic matter from wood, grass and residues in strong organic acid produced in the charcoal manufacturing process for groundwater that is rich in salts such as iron and calcium, and curing it for an extended period, thereby reducing the adhesion to drainage collection pipes.SOLUTION: In a method for preventing blockage of collection and drainage pipes in collection and drainage facilities, this method makes it possible to maintain ionization of salts characterized by adhesion to blockages and alleviate adhesion to collection and drainage pipes by using solidified fulvic acid and humic acid produced by soaking an appropriate amount of undecomposed organic matter from wood, grass and residues in strong organic acid produced in the charcoal manufacturing process for groundwater that is rich in salts such as iron and calcium, and curing it for an extended period.SELECTED DRAWING: Figure 1
