Problems solved by technology

However, a small amount of sewage still enters the river in sunny days due to mixed connection reconstruction of upstream pipe networks and insufficient diversion of rainwater and sewage in some river courses. The overflow pollution caused by mixed flow sewage in rainy days and the non-point source pollution of rainwater produced in areas with complete diversion system still have an impact. Important factors of river water quality and water ecology

Abstract

The invention discloses a riverway in-situ purification method. The method comprises the following steps that the in-situ purification device is placed under the water surface of a riverway. The in-situ purification device comprises fixing frames, a fixing rod is arranged between the fixing frames, an elastic filler and an aeration hose are arranged on the fixing rod, the lower portion of the fixing frame is a fixing pile, and a fixing disc is arranged in the middle of the fixing pile, the fixing pile below the fixing disc is inserted into the river bottom, a floating type floating bed is fixed at the upper part of the fixing frame, floating-leaf plants are placed on the floating type floating bed, and the aeration hose is externally connected with an external aeration system for aeration. By adopting the device, the functions of in-situ water quality purification and water ecology construction can be realized.

Description

technical field [0001] The invention designs an in-situ purification method of a river, which is used for water quality purification, in-situ treatment and water ecological construction of the river, and belongs to the technical field of urban water environment comprehensive treatment. Background technique [0002] Urban water environment governance is an important part of the battle against pollution. In 2015, the Water Pollution Prevention and Control Action Plan ("Water Ten Measures") and relevant contents of sponge city construction were promulgated, which clearly put forward the goals and requirements of my country's water environment pollution control, urban drainage, regional water environment governance and urban drainage and other ecological environmental issues The solution to the problem has become an urgent need to improve people's livelihood and promote social harmony and stability. [0003] The urban water environment treatment follows the technical route of "c...
