Abstract

The present invention relates to the field of water treatment, in particular to a domestic sewage comprehensive utilization system based on black ash diversion, which includes an anaerobic fermentation tank, a methane air bag and a water tank; the anaerobic fermentation tank is provided with a stirring device, and the stirring device The stirring impeller is arranged in the inside of the anaerobic fermentation tank, and the stirring impeller is connected to the power mechanism outside the anaerobic fermentation tank through the stirring shaft, and the anaerobic fermentation tank is connected through the middle water pipeline I; the position of the water tank is higher than that of the anaerobic fermentation tank. Oxygen fermentation tank, the bottom of the water tank is provided with a power pipeline, the power pipeline is connected to the power mechanism, the water flow in the power pipeline drives the power mechanism, and the power mechanism drives the stirring impeller to work; the methane in the methane air bag is used for gas water heaters, the life of the present invention The anaerobic fermentation tank in the sewage comprehensive utilization system also effectively utilizes the gravitational potential energy of gray water, and provides kinetic energy for the agitation of the anaerobic fermentation tank through the flow of gray water. This system reduces the input of external energy and reduces energy consumption.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a domestic sewage comprehensive utilization system based on black ash diversion. Background technique [0002] Domestic sewage contains a large amount of heat energy. At present, most of the treatment of domestic sewage is transported to sewage treatment plants for centralized treatment and then discharged. A small part of sewage is recycled after simple treatment. This will not only cause the consumption of sewage energy and Waste, there is also the problem of difficult sewage treatment and high operating costs of sewage treatment plants. [0003] With the improvement of living standards, building facilities are becoming more and more perfect. In order to classify domestic sewage, some buildings have realized the black and ash separation of domestic sewage, that is, the drainage in the building uses black water (fecal sewage) and ash. Water (bathing sewage) is collected and utili...
