An integrated micro-dynamic ecological treatment device for rural dispersed sewage

Abstract

The invention provides a rural decentralized-wastewater integrated micro-dynamic ecological treatment device and belongs to the field of sewage treatment with an aim to solve problems in an existing rural decentralized-wastewater treatment device. The device comprises a regulating tank, a hydrolytic acidification tank, an intermittent aeration tank, a sedimentation tank, a water storage tank, an underground infiltration system and an electronic control system; the top end of the regulating tank is higher than the top of each of the hydrolytic acidification tank, the intermittent aeration tank, the sedimentation tank, the water storage tank and the underground infiltration system; the regulating tank is connected with the hydrolytic acidification tank, the hydrolytic acidification tank is connected with the intermittent aeration tank, the intermittent aeration tank is connected with the sedimentation tank, the sedimentation tank is connected with the water storage tank, and the water storage tank is connected with the underground infiltration system; the electronic control system is connected with the regulating tank, the hydrolytic acidification tank and the intermittent aeration tank respectively. The device is suitable for sewage characteristics of rural areas and economy technologies, free of attendance of professional technicians, good in treatment effect and compact in structure.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an integrated micro-dynamic ecological treatment device for scattered sewage in rural areas. Background technique [0002] With the rapid economic development, China's water environment pollution has gradually spread from cities to rural areas. Rural sewage is mostly discharged directly without treatment, mainly because in rural areas, farmers live in scattered places and it is difficult to collect sewage. If it is discharged into the municipal pipe network for centralized treatment, a large-scale pipe network system needs to be laid, which is expensive and the sewage is far away. The long-distance transportation will lead to the leakage of sewage, which poses a serious threat to the groundwater. In addition, the rural economy is backward, the residents' awareness of environmental protection is weak, and the water pollution problem is not paid enough attention, which makes the wat...

Problems solved by technology

Most of these processes have high investment and operating costs, complex management, large floor area, and unsatisfactory treatment effects.

In addition, although the small sewage treatment device has achieved structural integration, it has the disadvantages of many ancillary equipment and insufficient compact structure; the impact resistance of the system after process miniaturization is poor; most devices have a good removal effect on organic matter, while for Nitrogen and phosphorus cannot meet the emission standards, and it is difficult to achieve large-scale promotion and application

[0004] Therefore, in view of the characteristics of rural scattered sewage and the shortcomings of existing technologies such as complex management, poor treatment effect, and large footprint, it is necessary to find a kind of equipment that does not require professional and technical personnel to be on duty, has good treatment effect, and has a compact structure suitable for rural decentralized sewage purification. The integrated micro-power ecological treatment device
