Vertical type integration sewage treatment device

Abstract

The present invention discloses a vertical type integration sewage treatment device characterized by comprising a water pump, an adsorption mixing tank, an anaerobic tank, a return passage, an aerobic tank, a circulation passage, a rapid precipitation reflux tank, a water collecting tank and a bag filter apparatus, incoming water enters the adsorption mixing tank by the water pump to mix with return sludge and circulating water, the water after mixing enters the anaerobic tank for biological denitrification and biological phosphorus release processing, the processed water flows into the aerobic tank for the biological nitrification and phosphorus uptake, the water processed by the aerobic tank enters the circulation passage, most of the water in the circulation passage flows into the adsorption mixing tank by the return passage, a small portion of the water enters the rapid precipitation reflux tank for mud-water separation of the incoming water in the rapid precipitation reflux tank, and clarification water flows into the bag filter apparatus by the water collecting tank to remove suspended solids in the water. The vertical type integration sewage treatment device is exquisite in structure, strongly practical, suitable for being used in rural areas lack of 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. [0003] Combined wi...
