METHOD FOR TREATING WATER AND FLOCCULANT FOR ORGANIC SUBSTANCES

摘要

Provided are a method for treating water and a flocculant used in the method. The method includes the steps of adding a first polymer compound formed by multiply binding a first repeating unit into water to be treated, and adding a second polymer compound formed by multiply binding a second repeating unit into the water. The first repeating unit includes a first linked main chain which constructs a main chain via repeatedly bound one another, and an adsorption site directly or indirectly bound to the first linked main chain so as to adsorb organic compounds contained in the water to be treated. The second repeating unit has a similar structure to the first repeating unit except that the number of carbon atoms in the second linked main chain is different from that in the first linked main chain. The flocculant includes the first and second polymer compounds.

1. A method for treating water comprising the steps of:
adding a first polymer compound formed by multiply binding a first repeating unit into water to be treated, and adding a second polymer compound formed by multiply binding a second repeating unit into the water to be treated, wherein the first repeating unit comprised of a first linked main chain which constructs a main chain via repeatedly bound one another, and an adsorption site directly or indirectly bound to the first linked main chain so as to adsorb organic compounds contained in the water to be treated, and the second repeating unit comprised of a second linked main chain which constructs a main chain via repeatedly bound one another, and an adsorption site directly or indirectly bound to the second linked main chain so as to adsorb organic compounds contained in the water to be treated, wherein the number of carbon atoms in the second linked main chain is different from the number of carbon atoms in the first linked main chain.
