Embodiment Construction

[0023] In order to clearly illustrate the features of the device and method, the device and method will be described below through a specific implementation mode combined with the accompanying drawings.

[0024] Such as figure 1 , 2 As shown, the shape of the main body of the device is cylindrical, and the central cylinder divides the main body of the device into a central cylindrical area and an external annular area, thereby maximizing the use of volume and reducing the volume of the main body of the device; the central cylindrical area is an anaerobic zone 11, A baffle plate 2 and an overflow weir 3 are arranged in the middle to form an overflow area 12, so that the water flow forms a baffle between the anaerobic area 11 and the overflow area 12, preventing sludge from flowing into the outer ring area; four blocks are set in the outer ring area Partition plates 4, 5, 6, 7 form four chambers, which are aerobic zone 13, anaerobic zone 14, aerobic zone 15, and sedimentation z...

Abstract

The invention belongs to the sewage treatment field, and especially relates to a household integrated device for rural domestic sewage treatment, and a method thereof. Separator plates divide the internal of the cylindrical domestic sewage treatment device into a plurality of aerobic areas and an anaerobic area, and the upper part or the lower part of every separator plate is perforated to make sewage move in a baffling manner in the treatment process from water feeding to water discharging in order to increase the volume utilization rate; and the outer ring aerobic areas and the anaerobic area are respectively filled with a filler, aeration tubes are arranged in the anaerobic areas, and the device can efficiently remove carbon and nitrogen and realize sludge reduction under an anaerobic-aerobic environment repeated alternation condition. The device and the method have a high sewage treatment efficiency, the device has the advantages of simple structure, small size and low energy consumption, and can run for a long term without professional management, and the device and the method are especially suitable for village single-house domestic sewage treatment.

Description

1. Technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an integrated device and method for household sewage treatment in rural areas. 2. Background technology [0002] As my country enters into a well-off society in an all-round way, it is imperative to popularize domestic sewage treatment in rural areas. Considering the national conditions, it is the main form of rural domestic sewage treatment to carry out decentralized sewage treatment in units of households or village groups in my country. Therefore, in the densely populated and economically developed rural areas of our country, the use of small and micro integrated devices to treat sewage will be the key direction of future technological development. [0003] At present, a variety of integrated sewage treatment devices have been developed in a targeted manner at home and abroad. The mature product technology is most famous for the small purification tanks from Japa...
