Abstract

The invention discloses an urban inland river water quantity and water quality optimization regulation and control method. The method comprises the following steps: 1, carrying out current situation investigation on rainfall and evaporation quantity of an area, a pollution source of the area, hydraulic engineering of the area, river basic information, a river water environment, a river ecosystem and the like; 2, analyzing current situations such as regional pollution sources, river channel water quality and quantity, regional water environment capacity, river channel ecological water demand, regional fresh water availability, water regulation quantity and influence range, feasibility of water reuse in an intra-regional sewage treatment plant, regional water ecology and the like; and 3, providing a water quantity and water quality optimization regulation and control method. The method is based on deep analysis of the hydrological water environment in a city; an urban inland river waterquantity and quality optimization regulation and control scheme can be put forward in a targeted mode, and therefore the problems that the water body river network water quality is generally poor, thenitrogen and phosphorus content is high, the transparency is poor, the water supplementing source is single, a water ecosystem is imperfect, and the water body self-purification capacity is low in the urban inland river are solved.

Description

technical field

[0001] The invention relates to the field of water environment, in particular to a research method for optimizing and controlling water quantity and quality of urban inland rivers. Background technique

[0002] The situation of the national water environment is severe, which is mainly reflected in three aspects: first, as far as the entire surface water is concerned, the proportion of seriously polluted water bodies of inferior V category is relatively high, about 10% of the country, and some river basins even greatly exceed this number. Second, some river sections flowing through cities and towns, some ditches, ponds and dams at the junction of urban and rural areas are generally heavily polluted, and due to organic pollution, there are many black and odorous water bodies, many affected people, high public attention, and high dissatisfaction ; Third, the number of water environmental emergencies involving drinking water safety is still quite large.
