Abstract

The invention discloses a pre-circulating water purification device suitable for large-yield wetland, and belongs to the field of water purification engineering. In a process of wetland construction and planning, the quality of raw water can be affected by diversion water, and the water quality spatial and temporal difference is great; moreover, a conventional wetland water purification device, mixing of a flocculant and raw water cannot adapt to the change of the flow quantity, and the problems of large maintenance and management quantity and high operation cost are solved. With arrangement of a water diversion pump station, a flocculant adding platform is arranged at the upper end of a water intake pipe, high speed rotation is performed by a high-speed centrifugal impeller, the coagulantand the raw water can be mixed effectively at high speed, the chance of collision between fine alum flocs is increased, and the settling performance is improved. By arrangement of a cyclotron treatment device, the fully mixed raw water in the water diversion pump station is flocculated and precipitated in the cyclotron treatment device; good precipitation effect and landscape effect can be obtained; after flocculation is completed, a dredging pump can be turned on, sludge is pumped to a sludge compressor and compressed, and the resource disposal is facilitated.

Description

technical field [0001] The invention relates to the field of water purification engineering, in particular to a pre-circulation water purification device suitable for wetlands with large production capacity and clearing volume. Background technique [0002] Driven by the global response to climate change, the world is undergoing a dramatic change in the way economic and social development occurs. Since the 21st century, ecosystem protection has been gradually integrated with urban construction planning. The construction of a large-scale wetland system can effectively alleviate the urban heat island effect and improve the energy-saving effect of buildings. In addition, the wetland system can also improve the urban landscape, increase the public green space, and enrich the diversity of urban species. However, in the process of wetland park construction planning, the water quality of wetland water sources will be affected by water diversion, and the water quality varies great...
