Embodiment 1

[0035] A rural single-household domestic sewage treatment system includes a domestic sewage discharge source located on the ground, an underground sewage treatment device, and a rooftop sewage purification device. The domestic sewage discharge sources are generated and collected from toilets, squatting toilets, kitchens, baths, etc.

[0036] The underground sewage treatment device includes a baffle anaerobic pool 1 and a water collection adjustment pool 2. The outlet of the domestic sewage discharge source is connected to the entrance of the baffle anaerobic pool 1, and the sewage from the domestic sewage discharge source is in the baffle anaerobic tank. Oxygen tank 1 entrance is discharged into the baffle anaerobic tank 1, and the bottom of the baffle anaerobic tank 1 is provided with a slag outlet 5, and the outlet of the baffle anaerobic tank 1 is provided with an overflow pipe 3; in this embodiment, The sewage flow channel of the baffle anaerobic tank 1 is G-shaped when vi...

Embodiment 2

[0047] The process of using the system described in embodiment 1 to process domestic sewage comprises the following processing steps:

[0048] 1) Discharge the domestic sewage into the baffle anaerobic pool 1, store it for 6 days, overflow to the water collection adjustment pool 2, and store it for 2 days;

[0049] 2) Convey the upper material of the water collection adjustment tank 2 upwards, and control the conveying flow rate to 1m 3 / h, enter the pipeline mixer 7, and the nano-dissolved air water produced by the micro-nano aerator 8 is transported into the pipeline mixer 7 at the same time, and the delivery flow rate is 0.8m 3 / h;

[0050] 3) The mixed material enters the first planting area 16 from the first water collecting pipe 10 , and is discharged from the third planting area 18 into the clear water pool 15 .

[0051] 4) Part of the water in the clean water tank 15 is returned to the micro-nano aerator 8 to form a circulation, which effectively improves the removal...

Abstract

The invention relates to a rural single-household domestic sewage treatment system and process, including the following treatment process: 1) discharge the domestic sewage to the baffle anaerobic pool, and then overflow to the water collection adjustment pool; 2) drain the upper layer of the water collection adjustment pool The material is transported upwards and enters the pipeline mixer, and the nano-dissolved air water produced by the micro-nano aerator is simultaneously transported into the pipeline mixer; 3) The mixed material enters the first planting area from the first water collection pipe, and then is transported by the third The planting area is discharged into the clear water pond. The rural single-household domestic sewage treatment system can collect and treat domestic sewage on the spot, and the effluent can reach the first-class A standard in the discharge standard of GB 18918-2002.

Description

technical field [0001] The invention belongs to the field of domestic sewage treatment, and in particular relates to a rural single household domestic sewage treatment system and process. Background technique [0002] With the rapid development of China's economy and society, rural living standards are getting higher and higher. Flush toilets, washing machines, bathing facilities, automatic dishwashers, etc. have entered thousands of households. Water consumption and domestic sewage discharge have increased rapidly, resulting in a large amount of domestic sewage. However, although the rural population is large and produces a large amount of sewage, the population is scattered, and usually hundreds of people gather into a village, resulting in a large amount of rural domestic sewage. Large, large dispersion area, difficult collection, low efficiency of domestic sewage collection facilities, incapable of comprehensive and complete collection of domestic sewage, and domestic se...
