8、ronment in lock areas, finding that the water pollution in lock areas was very serious, and they are prone and high-risk places for water quality decline and water pollution in water conservancy facilities. Therefore,

9、 the lock turbulent water on organic matter degradation problem has received extensive attention, but research is not enough, neither as the information. Distribution system is an important part of the lock, its main

10、 role is to complete water supply and drainage in the shortest time, in order to make the water level up and down consistent. The hydrology in lock areas is absolutely different from that in natural rivers because of

11、the velocity and high head of water in the distribution system. Most water pollution processes are not orderly, stable, balanced or certainly, but in a disorderly, non-stable, non-balanced and random turbulent state,

12、there is a turbulence in the nonlinear interaction [1]. In this paper, Gezhouba lock, for example, through the turbulent waters of the experimental control degradation of organic law [2], and using on-site monitoring
