Embodiment 1

[0027] The water outlet room 3 of the biogas digester is provided with a diversion wall 6, which is located between the gray water inlet unit 4 and the water outlet 5; the upper end of the diversion wall 6 is flush with the upper end of the water outlet 5, and the bottom end of the diversion wall 6 is suspended And be lower than water outlet 5 bottoms. The diversion wall 6 can effectively prevent the short circuit between the gray water inlet unit 4 and the water outlet 5 .

[0028] The size of the water outlet 5 is 20-40cm, 20-40cm, and the bottom of the water outlet 5 is 10-20cm higher than the water inlet of the post-treatment system. The horizontal distance between the diversion wall 6 and the biogas tank fermentation room 2 is 30-40cm, and the vertical distance between the bottom of the diversion wall 6 and the bottom of the water outlet 5 is 20-30cm.

[0029] The water outlet room 3 of the biogas digester is provided with a slag retaining wall 7, which is located betwee...

Abstract

The invention belongs to the field of environmental protection, and discloses a household domestic sewage purification device which is composed of a black water inlet unit (1), a grey water inlet unit (4) and a methane tank. The household domestic sewage purification device is characterized in that the black water inlet unit (1) is connected with a fermentation room (2) of the methane tank, and the grey water inlet unit (4) is connected with a water outlet room (3) of the methane tank. According to the household domestic sewage purification device, the technical defects that black water and grey water in existing domestic sewage are drained to the fermentation room of the methane tank together, the sewage staying time is short, and the purification effect is poor are overcome, the black water and the grey water are segmented by the household domestic sewage purification device to enter a methane tank processing system, the purification effect is improved, and the investment is reduced.

Description

Technical field: [0001] The invention belongs to the field of environmental protection, and in particular relates to a household domestic sewage purification device. Background technique: [0002] The existing harmless treatment devices for household domestic sewage are mainly biogas digesters. At present, there are more than 40 million biogas digesters in the country. Biogas digesters play an important role in purifying the rural environment and changing the appearance of the countryside, especially in purifying toilets Wastewater plays an active role. Domestic sewage can be divided into black water (toilet wastewater) and gray water (washing water, kitchen water). Black water has a high concentration and may contain pathogenic microorganisms. Gray water is low in concentration, but contains some solid impurities. If the black water and gray water are discharged into the fermentation room of the digester, the residence time of the sewage in the digester is short, the p...
