Đánh giá tiềm năng khai thác các trạm bơm tưới dọc sông Hồng để lấy nước vào hệ thống sông Nhuệ - Đáy nhằm cải thiện môi trường nước

Abstract

Facing the situation that the Red River water level is getting lower and lower, since 2010, Hanoi People's Committee has installed many removable pumping stations such as Phu Sa, Xuan Phu, Ba Giang, and upgrading and building new pumping stations such as Dan Hoai, Hong Van to get water for irrigation. These pumping stations are generally operated few times during a crop. For example, in the winter-spring crop, there will be only about four to five times of operation of taking water for irrigation. After each period of taking water lasts from five to seven days, the pump station will stop operation and routine maintenance. Particularly for removable pumping stations, after each water taking season, they must be dismantled and brought into workshops for preservation and storage. This shows that the existing pumping stations have not yet been fully used to serve other purposes, such as the purpose of supplying water sources for the Nhue-Day river system to enhance the water purification, and to increase water quality.

In this paper, the authors will propose suitable pumping stations with potential for regularly taking water from the Red river into the Nhue - Day river in order to enhance the river water quality
