T/CAQI 178-2021 Preventing and controlling eutrophication of important lake and reservoir water sources in the Guangdong-Hong Kong-Macao Greater Bay Area: Technical guidelines

Scope

Scope: This document stipulates the basic principles, state identification methods, diagnosis procedures for eutrophication, evaluation methods and grading standards for the prevention and control of eutrophication in important lake-reservoir type water sources in the Guangdong-Hong Kong-Macao Greater Bay Area, as well as the prevention and control objectives and tasks, key prevention and control technologies, and long-term management mechanisms for eutrophication in important lake-reservoir type water sources. This document is applicable to the scientific diagnosis and evaluation of eutrophication in important lake-reservoir type water sources in the Guangdong-Hong Kong-Macao Greater Bay Area, the screening of comprehensive treatment technologies, and the preparation of treatment plans. The construction of eutrophication standards for important lake-reservoir type water sources in the Guangdong-Hong Kong-Macao Greater Bay Area has been largely completed, but the prevention and control of eutrophication in some water bodies remains urgent. Important lake-reservoir type water sources in the Guangdong-Hong Kong-Macao Greater Bay Area refer to lakes and reservoirs listed in the "National Important Drinking Water Source List" (Letter on Water Resources [2016] No. 383), excluding those in Hong Kong and Macao; unlisted lake-reservoir type water sources can refer to this document for implementation. Main technical content: The main causes of eutrophication, identification of eutrophication status, and diagnosis procedures for eutrophication problems.
