Embodiment 1
[0019] Embodiment 1: as figure 1 and figure 2 As shown, the shell 1 of the sewage treatment device adopts a commercialized 200L standard iron drum. The housing 1 is divided into two independent processing units by a partition 5 . Part of the end of the water inlet pipe 2 and the water outlet pipe 3 of the device extends to the bottom of the device, and a certain distance is left for water inlet and outlet. This design makes the water flow in the device rise first, then fall and finally rise, preventing The occurrence of short flow phenomenon reduces the dead zone of water flow at the same time. Outlet pipe 3 is connected with a pipe section 33 with a larger diameter of 70 or 90mm with expander 32 at the end of part of the device, so as to reduce the flow velocity of the water flow in the pipe and play the role of sedimentation.

The invention relates to an integrated rural distributed sewage treating device capable of being combined and assembled. The overall device has a cylindrical structure and consists of a housing, a water inflow pipe, a water outflow pipe, a suspended piece holder, a partition plate, a top cover, an electric motor holder and an electric motor, wherein the partition plate is vertically arranged in the housing to divide the device into two independent treating units; the holder is arranged inside the housing; one end of the water inflow pipe is positioned on the upper part of the housing, while the other end is inserted into the bottom of the housing; one end of the water outflow pipe is positioned on the upper part of the housing, while the other end is inserted into the housing; the top cover is positioned on the top part of the housing and supported on the housing by a bracket; the electric motor holder is arranged on the internal wall of the top cover; and the electric motor is fixed on the electric motor holder. The device is modified and manufactured by taking a commercial standard iron bucket of 200L as a reactor unit, and has a simple structure and low cost. Components for internal aeration, stuffing and the like all can be flexibly combined and disassembled for multiple functions. Both the water inflow and outflow pipes of the device are provided with flanges, therefore aplurality of treating units can be optionally combined according to process requirements so as to meet the treatment requirements of rural distributed sewage in different regions and different household numbers.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and relates to rural decentralized sewage treatment technology, specifically a combinable and assembled rural decentralized (1 to 5 households) sewage treatment device. Background technique [0002] In recent years, my country's sewage treatment plants have been continuously built, and the sewage treatment rate has continued to increase, but they are mainly concentrated in cities, and sewage in most rural areas of the country cannot be treated. However, my country has a large rural population, most of the rural areas have not built sewage pipe networks, public facilities cannot keep up with the needs of development, a large amount of domestic wastewater is discharged into various water bodies without treatment, and the proportion of rural sewage discharge in the total sewage discharge is increasing. bigger and bigger. At present, the whole country has a great impact on the living...
