Embodiment 1
[0051] Among them, the water demand for maintaining water quality in the first start-up area and the later development area Q SZ It depends on the pollution degree of the river itself in the current area, and can be calculated by the following formula: ;
[0052] The calculation of the pollution-holding capacity (M) refers to the "Calculation Regulations for the Pollution-Holding Capacity of Water Areas" (GB / T25173-2010). When the water flowing into and out of the lake (reservoir) is balanced, the formula is as follows:
[0053] The self-purification amount of pollutants entering the river (W self-purification) refers to the self-purification capacity of the river. On the basis of fully considering the self-purification function of the river, it includes physical self-purification capacity (volatilization, diffusion, dilution, sedimentation, adsorption), chemical self-purification capacity (oxidation, hydrolysis, etc.) and For biodegradation (photosynthesis, respiration), t...

The invention discloses a multi-mode ecological water replenishing system and method for a new urban district, and belongs to the technical field of ecological water replenishing. Comprising the following steps: acquiring at least one water source, and matching a corresponding water quality treatment technology based on a water quality problem existing in the water source to obtain a plurality of ecological water supplementing water sources meeting a river entering water quality standard; the method comprises the steps of calculating the ecological water supplementing demand quantity of a river channel according to a scheduling mode of river network water resources, selecting or switching a corresponding water supplementing mode based on the ecological water supplementing demand quantity, and completing water supplementing according to a preset region and / or a preset stage based on the water supplementing mode in a multi-water-source complementary mode. The invention provides the total amount of water resources required for maintaining the ecological environment of the urban new district river channel to exert normal substance circulation, energy flow and information exchange, protecting river aquatic organisms, maintaining the health of the ecological system and meeting the sustainable utilization of water resources, and provides a river network calculation model about the total amount of water resources.
Description
technical field [0001] The invention belongs to the technical field of ecological water replenishment, and in particular relates to a multi-mode ecological water replenishment system and method for urban new districts. Background technique [0002] Urban rivers are one of the main carriers of the urban ecological environment, creating a beautiful living environment for urban residents, and providing various basic guarantees and related resources for the sustainable development of the city where they are located. [0003] At present, most rivers are artificially generated, so they basically belong to urban rivers without natural upstream water, and can be ecologically replenished by artificial means. That is to add ecological water replenishment measures on the basis of pollution source control, by supplementing the environmental factor that is missing in the damaged river ecosystem—water, improve water fluidity, increase water environment capacity and self-purification capac...
