A lake water purification device and its treatment method

Abstract

The invention discloses a lake water purification device. The lake water purification device comprises a treatment tank, a disinfection tank and ecological wetland, wherein a first treatment area anda second treatment area are arranged in the treatment tank from left to right sequentially; a filtration area and an aeration area are arranged in the first treatment area, a biological stuffing device and a wavy adsorption layer are arranged in the second treatment area, a sprinkler and a stirring device are arranged in the disinfection tank, the ecological wetland comprises first ecological wetland and second ecological wetland, and a water collecting pipe is arranged at the bottom of the first ecological wetland and communicated with the second ecological wetland. The treatment method comprises steps as follows: (1) preliminary treatment of sewage; (2) disinfection treatment of sewage; (3) ecological treatment of sludge; (4) later clearing. The lake water purification device is simple in structure and high in practicability, firstly, the treatment tank removes impurity particles in the sewage, the disinfection tank kills germs in the sewage, and finally, the ecological wetland performs ecological treatment on the sewage, so that the treated sewage has better water quality and the water is clearer.

Description

technical field [0001] The invention relates to a lake water purification device and a treatment method thereof. Background technique [0002] In the formation and development of cities, lakes, as important resources and environmental carriers, are related to urban survival, restrict urban development, and are important factors that affect urban style and beautify the urban environment. Urban rivers and lakes have various ecological functions such as supplying water, providing green space, protecting the environment, transportation, and cultural education, and have shown irreplaceable significance in urban construction and urban space development. With the acceleration of urbanization in our country, land development and utilization on both sides of the river have damaged the functions of urban rivers and lakes, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing lake water pollution, water quality deter...

AI Technical Summary

Problems solved by technology

Existing water purification treatment devices are bulky, costly, and complex in actual operation, which is inconvenient for later maintenance and cleaning; the burden on the device is large, and it is easy to cause overload work, resulting in a short service life of the device and requiring frequent maintenance , the cost of post-maintenance is high, and the processing process is less, only one or two processing, the processing time is short, resulting in poor processing effect
