What are the specific standards for environmental protection requirements for washing water labels?

The specific standards for environmental protection requirements of washing water labels involve multiple aspects, mainly including national and local emission standards, washing water requirements, and technical requirements for environmental labeling products.
National and local emission standards: The washing and dyeing industry is required to comply with the national comprehensive sewage discharge standard (GB8978-1996) or stricter local standards (such as DB11/307-2013). When local standards are stricter than national standards, local standard 12 shall be implemented.
Washing water requirements: Washing water must meet specific conditions, including pH value, total hardness, iron and manganese content, etc., to ensure washing effectiveness and reduce environmental pollution.
Technical requirements for environmental labeling products: Household detergents, laundry shops, and laundry factories must comply with the technical requirements for environmental labeling products, including standards such as HJ 458-2009 and HJ 1162-2021, covering the environmental performance of the products and the environmental requirements during use.
In summary, the environmental requirements for washing labels involve multiple levels of standards and regulations, aimed at ensuring that the impact of washing products and their use on the environment is minimized.
