Abstract

The invention discloses an underground sewage purifying device and a sewage purifying method, and relates to the technical field of sewage treatment equipment. The underground sewage purifying device is provided with a first filtering tank, a second filtering tank, a reservoir, an equipment room, a first purified water storage tank, an aeration grit basin, and a biological treatment tank sequentially from top to bottom; one side of the biological treatment tank is adjacent to a second purified water storage tank, water treatment and water utilization are organically combined together through the device, the device is small, and the defect of large occupied area of a common sewage plant is overcome. In addition, the device is simple in treatment mode of the sewage, the operation cost is lowered, the device uses a water turbine to drive a generator to generate electric energy, the electric energy needed for the operation of the device is fully provided by the device, the operation cost of the device is lowered, and the surplus energy can also be used for other purposes like illumination.

Description

technical field [0001] The technical field of sewage treatment equipment of the present invention, more specifically relates to an underground sewage purification device and a sewage purification method. Background technique [0002] my country's fresh water resources are scarce, and the amount of underground fresh water natural resources only accounts for 1 / 3 of the total domestic water resources. In the past 20 years, the amount of groundwater extraction has increased at an average rate of 2.5 billion square meters per year. More than 400 cities across the country have exploited groundwater, and groundwater accounts for about 30% of the total urban water use. Northern cities mainly exploit groundwater, and the proportions of groundwater utilization in North China and Northwest cities are as high as 72% and 66% respectively. Due to the lack of a scientific development concept in the development and utilization of groundwater resources, a large amount of groundwater has bee...
