T/ZHLSSH 005-2024 Self-designed nano-catalytic wastewater treatment agent
Basic Information
Scope
Scope: This standard specifies the technical requirements, test methods, inspection rules, marking, labeling, and packaging for self-formulated nano-catalytic wastewater treatment agents. This standard applies to the self-formulated nano-catalytic wastewater treatment agents produced by the titanium dioxide industry using the sulfuric acid method. The product is mainly used for the treatment of dyeing wastewater and difficult-to-decompose organic wastewater.
