ABSTRACT
With the development of city, the water pollution in the city is more and more
serious. It has become an important issue to solve the problem of urban black smelly
water body in the development of the city. As an engineering measure to solve the
problem of water environment, the water system connected engineering is
characterized by quick effect and is beneficial to the rational allocation of water
resources. In the water system connected engineering, it is one of the key problems to
determine the reasonable water transfer flow.
At first, the summary of the research progress is put forward in this paper on
China's current situation and river connectivity successes have been achieved, and a
two-dimensional hydrodynamic numerical simulation of water quality research
progress at home and abroad are summarized, laying the groundwork for the
following numerical simulation research.
Then the geographical location of the water system in the city center of Haikou,
the composition of the water system and the water quality of the river system are
introduced. At the same time, the paper puts forward the solution of the water system
connectivity and the layout of the connected project in the central urban area of
Haikou, so as to determine the research direction and the research question of this
paper.
Secondly, according to the research results of the original river self purification
water demand, multi-function formula of river self- purification water requirement
is put forward. Then, according to the population living conditions and the living
conditions of the local people in the city of Haikou City, the pollutant loads
discharged into the river are quantitatively predicted. Finally, the distribution of
pollutants discharged into the river by using the multi zone, the river self purification
water demand calculation of the river ecological self purification water demand, so as
to determine the water diversion scheme of river connectivity.
The theoretical knowledge of this model , using the research and thorough
analysis the control equation of one dimensional hydrodynamic water quality and
discrete methods pave the way for the theoretical basis for the following
one-dimensional hydrodynamic and water quality simulation. At the same time, the
