Regulation system and method for dual-synaesthesia damp, black and odorous river way

Abstract

The invention discloses a method and a system for treating a black and odorous river channel with dual synaesthesia tides. The treatment system includes an upstream water inlet gate, a downstream water outlet gate and a control center; The upstream inlet estuary of the river channel, the downstream outlet gate is arranged at the downstream outlet estuary of the dual-sense tide black and odorous channel; the upstream inlet sluice gate and the downstream outlet sluice gate are respectively connected with the control center. Through the PLC automatic control system of the control center, according to the liquid level information fed back by the inner liquid level gauge and the outer liquid level gauge, jointly dispatch the opening and closing of the upstream inlet gate, downstream outlet gate, tributary estuary gate, large-flow axial flow pump, and large-scale drainage vehicle. closure. The method of the invention is suitable for the rapid and effective relief of the black and odorous river channels of the double synaesthesia tide, and does not affect the functions of flood control, navigation, waterlogging drainage and the like of the river channel, and is a double channel with the advantages of short construction period, low investment, low operation cost, convenient maintenance and the like. Comprehensive management methods for black and odorous rivers.

Description

technical field [0001] The invention relates to the technical field of river course management, in particular to a treatment system and method for double-passage, tidal, black and odorous river courses. Background technique [0002] Since the reform and opening up, with the continuous and rapid development of my country's economy, many rivers have been seriously polluted and become "black and smelly rivers". According to relevant statistics, more than 80% of urban rivers in my country are polluted, many of which have seasonal or even perennial "black and odorous phenomena". In 2015, the State Council promulgated the "Water Pollution Prevention and Control Action Plan" (referred to as "Water Ten Measures"), which put forward clear goals for river and lake water quality control. By 2020, black and odorous water bodies in built-up areas of prefecture-level and above cities will be controlled at 10%. Within, by 2030, black and odorous water bodies in urban built-up areas will b...

Problems solved by technology

In addition, in order to prevent storm surge disasters and urban drainage, estuaries have built gate control systems, and the unreasonable opening and closing process has further aggravated the deterioration of river water quality.

The treatment of tidal black and odorous rivers, like ordinary black and odorous rivers, requires comprehensive engineering measures such as pollution interception and pollution control to control external sources, sediment dredging to control internal sources, introduction of ecological base flow, and ecological restoration. Disadvantages such as huge funds, water quality improvement and long ecological restoration period
