A vertical integrated sewage treatment device

Abstract

The invention discloses a vertical integrated sewage treatment device, which is characterized in that it includes a water pump, an adsorption mixing tank, an anaerobic tank, a return channel, an aerobic tank, a circulation channel, a rapid sedimentation return tank, a water collection tank, and a bag filter device. The incoming water enters the adsorption mixing tank through the water pump and mixes with the returning sludge and circulating water. After mixing, the water enters the anaerobic tank for biological denitrification and biological phosphorus release treatment, and the treated water flows into the aerobic tank for biological nitrification and phosphorus absorption. , the water treated in the aerobic tank enters the circulation channel, most of the water in the circulation channel flows into the adsorption mixing tank through the return channel, and a small part of the water enters the rapid sedimentation return tank, which separates the mud and water from the incoming water, and the clarified water passes through The sump collects and flows into the bag filter device to remove suspended solids in the water. The invention has exquisite structure and strong practicability, and is suitable for use in rural areas lacking sewage treatment facilities.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a vertical integrated sewage treatment device. Background technique [0002] With the implementation of the "Water Pollution Prevention and Control Action Plan", the government has listed the rural water treatment market as one of the key projects. Regardless of market size or policy orientation, the rural water treatment industry is unprecedentedly strong. Due to the differences in China's rural areas in terms of topography, economic level, payment capacity, and effect requirements, the selection of rural sewage treatment technology routes should be tailored. In fact, due to the particularity of China's rural areas, relevant national authorities such as the Ministry of Housing and Urban-Rural Development, the Ministry of Environmental Protection, and the Water Affairs Bureau have not yet recommended specific technical routes in terms of technical selection.
