Embodiment Construction

[0014] See the accompanying drawings: a two-stage horizontal integrated sewage treatment device, which is characterized by comprising a grid 1, an anaerobic tank 2, a water passage 3, an aerobic tank 4, a circulation channel 5, a rapid sedimentation reflux tank 6, and a sump 10. Bag filter device 7, clean water pool 8, water pump 9, the incoming water is pretreated by grid 1, mixed with part of the water from aerobic pool 4, and then enters anaerobic pool 2 for biological denitrification and phosphorus release treatment , into the aerobic pool 4 to remove organic matter in the water for biological nitrification and phosphorus absorption. The water treated by the aerobic pool 4 is divided into two parts, one part is mixed with the water pretreated by the grid 1 and recirculated, and the other part enters the fast water through the circulation channel 5. The sedimentation reflux tank 6 and the rapid sedimentation reflux tank 6 separate the mud and water from the incoming water, a...

Abstract

The invention discloses a two-stage horizontal integrated sewage treatment device, which is characterized by comprising a grid, an anaerobic pool, a water passage, an aerobic pool, a circulation channel, a rapid sedimentation return pool, a water collection tank, a bag filter device, a clear water pool, water pump, the incoming water is pretreated by the grid, mixed with part of the water from the aerobic pool, and then enters the anaerobic pool for biological denitrification and phosphorus release treatment, and flows into the aerobic pool to remove organic matter in the water for biological nitrification and phosphorus absorption , the water after treatment in the aerobic tank is divided into two parts, one part is mixed with the water pretreated by the grid and recirculated, and the other part enters the rapid sedimentation reflux tank through the circulation channel, and the rapid sedimentation reflux tank 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, the bag filter device removes the suspension in the water and flows out the clear water, and the clear water is collected in the clear water pool and pumped out by the water pump. The invention has ingenious design and strong practicability, and is suitable for use in rural areas lacking sewage treatment.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a two-stage horizontal integrated sewage treatment device. Background technique [0002] According to the data of China Statistical Yearbook in 2013, from 2006 to 2013, the sewage treatment rate of cities nationwide rose from 55.7% to 99.1%, which is now close to saturation; the sewage treatment rate of counties rose from 13.6% to 82.6%. The rate has also increased significantly. Except for a few cities and towns to pick up waste and make up for vacancies and improve standards, the only shortcoming is the rural market. Data show that in 2012 China's rural sewage treatment rate was only 7.0%, and only a few developed provinces and cities such as Beijing, Shanghai, and Tianjin have achieved certain results in rural sewage treatment. Among them, the rural sewage treatment rate in Beijing and Shanghai exceeds 40%, but most of the other provinces have not fully rolled out, and...
