Self-circulation type urban central park water treating system and method

Abstract

The invention discloses a self-circulation type urban central park water treating system and method. The self-circulation type urban central park water treating system comprises a water inlet pipe, a control base station, a treatment module and a water outlet pipe, wherein the treatment module comprises a sedimentation tank and a water changer, a charger is installed at the upper end of the sedimentation tank and is connected to the control station, a water delivery pipe is connected between the sedimentation tank and the water changer, and a magnetic valve is installed on the water delivery pipe and is connected to the control base station. A pneumatic cylinder, a liquid level meter and a stirrer are installed in the water changer, and the pneumatic cylinder and the liquid level meter are connected to the control base station. The water treating method comprises the steps of 1 water guiding, 2 guided water filtration, 3 guided water inflow and 4 guided water change. The water treatment is achieved by adopting sedimentation and water change modes. Firstly, ferric sulfate is added to produce a flocculation effect on water, organic matter, nitrogen, phosphorus and other substances are wrapped and settle; then, and new water is injected into a river in a reduced-pressure vaporization and reliquefaction mode to dilute impurities in the water so as to reduce the concentration of the impurities.

Description

technical field [0001] The invention relates to a water quality treatment system and a treatment method, in particular to a self-circulating water quality treatment system and a method for a central urban landscape park. Background technique [0002] The urban central landscape park is an important part of urban greening and an important place for urban residents' daily life and leisure. Urban parks refer to parks other than natural parks, including comprehensive parks and park categories (such as theme parks, city squares, botanical gardens, zoos, etc.). In China, urban parks have: ecological functions, landscape functions, and disaster prevention functions to meet the needs of urban residents. In foreign countries, in addition to the functions of tourism, leisure, commercial activities and cultural promotion, it also has the function of beautification and humanization. [0003] As far as the city's central landscape park is concerned, the water quality of many landscape ...

Problems solved by technology

[0004] The present invention is a self-circulating water quality treatment system and method for urban central landscape parks. Aiming at the water quality problems of existing urban central landscape parks, a water quality treatment system is designed, and the water quality treatment is realized by means of sedimentation and water exchange; firstly, ferric sulfate is added, Make it produce flocculation, coat organic matter, nitrogen, phosphorus and other substances and settle; then inject new water into the river through decompression vaporization and liquefaction, dilute the impurities in the water, so as to reduce the concentration of impurities
