River training for the New River
The new river is a first-class tributary on the right bank of Weihe River, originating from the northern foothills of Qinling Mountain and entering the jurisdiction of Dongjiangdu Village, Jutai Town, Fenghuangxi New City, Xixian New District, with a main channel length of 32km and a watershed area of 303.8km2, of which the section of Fenghuangxi New City is 12km long, and the section of upstream Shuangyi District is about 20km. due to the complexity of various sources of pollution in the water, it is more difficult to manage the river. In recent years, because the new river is adjacent to the outer ring highway, the surrounding rapid economic development, industrial, living and other pollution generally increased, the characteristics of compound pollution is increasingly apparent. One of the most significant is man-made nitrogen, phosphorus emissions, emissions, environmental release rate, the impact of a wide range of the main features, and directly lead to the regional control section of ammonia nitrogen, phosphorus exceeded; water quality standards have fallen rapidly. This river management project used by the micro-nano bubble generation device, micro-nano bubble generation device principle is to use the complex structure of the gas and liquid to cut each other shear, cut the gas into nano level bubbles. When the bubbles reach the nanometer level, the bubble surface will carry a large number of charges, resulting in a large number of hydroxyl radicals, the charge can adsorb organic matter in the water, so that the organic matter upward aggregation, hydroxyl radicals can decompose the water ammonia nitrogen, COD and other organic matter, and then make the water quality of the river management project to continue to meet the standard stable.
