Ammonia Nitrogen Reduction
Origin
the MOENV, through all kinds of pollution management and remediation measures, gradually improves the water quality of 50 major rivers around the country, and have attained to significant results. However, Nankan River, New Huwei Creek, Erren River, Laojie Creek, Beigang River, Donggang River and Jishuei River are the 7 rivers that has lower ammonia nitrogen (NH3-N) level achievement rate. In order to hit the river water quality standard and ensure that no section of any river in Taiwan is heavily polluted, the MOENV will launch Sustainable Water Quality Promotion Plan: pilot project to reduce NH3-N, scheduled to take place from 2020 to 2023. The project, in line with the United Nations Sustainable Development Goal #6 (SDG6), is dedicated to clean water resources and sustainable water quality. It will continue reduce NH3-N or other pollutants emitted in the rivers so to address the public’s earnest desire for the enhancement of river water quality.
trend of percentage of rivers that are heavily polluted in taiwan
Up to 15.8% of the total lengths of 50 major rivers in Taiwan were subject to severe pollution in 2003, but the percentage has started to drop since then, and it was 2.8% as of 2019, indicating impressive results of river pollution remediation.
Implementation
7 rivers, namely Nankan River, New Huwei Creek, Erren River, Laojie Creek, Beigang River, Donggang River and Jishuei River are taken by the MOENV as demonstration rivers of water quality improvement. the MOENV focused on the implementation of installing pollution reduction facility, promoting pollution reduction measures and assessment, reviewing the collection of water pollution fund and enhancing auditing. The goal is to reduce pollution caused by NH3-N from heavy (>3 mg/L ) to medium (≦3 mg/L) as measured at the testing stations.
Working items and implementation strategies of the plan Update: September 5, 2019
Nankan River, Xinhuwei River, Er-Ren River, Laojie River, Beigang River, Donggang River and Jishui River are selected as demonstrational rivers for “installation of pollution reducing facilities,” “promotion and evaluation of pollution reducing measures” and “collection and inspection of water pollution control fund and intensified auditing.” The implementation includes establishment, control and supervision; the establishment is that of anomia and nitrogen pollution reducing facilities for water bodies, that of demonstration facilities for industrial ammonia and nitrogen reduction, and demonstrational subsidies for collecting and processing or recycled ammonia and nitrogen; the control consists of the plan for tracking and evaluation of implementation results, execution of pollutant reducing / resource conversion measures, and evaluation and review of promotion effects for water quality monitoring; and the supervision is composed of specific auditing and law enforcement, reduction of industrial discharge bypass or discharge of untreated wastewater, and collecting and auditing of water pollution control fund.
