tailieunhanh - Forecast of water quality of To Lich river based on scenarios of Ha Noi sewerage planning by using model Qual2k

To Lich River is well-known as a main drainage river and plays a vital role to the landscape distribution of Ha Noi city, which is currently polluted due to improperly untreated wastewater flow. Thanks to QUAL2K model, the variation of the river water quality has been forecasted by 4 particular scenarios. In the first scenario, the whole generated wastewater along To Lich River is not totally collected and treated. Scenario 2 is similar to scenario 1 except that To Lich River receives an addition of diluted water of 5 m 3 /s from Red River. In the third scenario, wastewater is mostly well managed but minor sources are not collected. Finally, the whole generated wastewater is properly treated and added with a diluted amount of 5 m 3 /s from Red River. The study pointed out that to meet standard of column B1, QCVN 08-MT:2015/BTNMT (Vietnam National Regulation), centralized and decentralized generated sewerage water need treated appropriately to lower BOD5 concentration below 20 mg/L to reach column B of National Standard 02:2014/BTNMT. | Forecast of water quality of To Lich river based on scenarios of Ha Noi sewerage planning by using model Qual2k
