Regulation system and method for single-pass tidal black-odor riverway

Abstract

The invention discloses a treatment system and method for a single-pass tidal black-smelly river. The control system includes an upstream river gate, a downstream estuary gate and a control center; For the river channel, the downstream estuary gate is set at the downstream estuary of the single-pass tidal black and odorous river channel; the upstream river channel gate and the downstream estuary gate are respectively connected to 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 river gate, the downstream river mouth gate, the tributary river mouth gate, the large flow axial flow pump, and the large drainage vehicle . The method of the present invention is suitable for fast and effective mitigation of single-channel tidal black and odorous rivers, and does not affect the functions of river flood control, navigation, and drainage. Comprehensive control measures for tidal black and odorous rivers.

Description

technical field [0001] The invention relates to the technical field of river course management, in particular to a system and method for controlling tidal black and odorous river courses through a single channel. 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 ar...

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
