Sewage treating vehicle

Abstract

The invention provides a moveable sewage treating vehicle which comprises a moving device, wherein a first aerobic pond, a secondary aerobic pond and a settling pond which are communicated with each other in turn are arranged on the moving device; a water inlet is formed at the upper end of the first aerobic pond; and a water outlet is formed at the lower end of the settling pond. An efficient flowing and separating biological technology is adopted; the sewage treating vehicle has the characteristics of high film-hanging speed, simpleniss in operation, stable running, excellent treating effect, low running cost, and the like; the sewage dispersed in remote rural areas can be moveably treated; and the construction cost of pipe network can be saved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a movable sewage treatment vehicle. Background technique [0002] When dealing with domestic sewage in remote areas and relatively non-concentrated vast rural areas, it is usually a domestic sewage treatment plant fixed in one place. Generally speaking, the process of domestic sewage treatment plant has the problem of sludge bulking, which requires special personnel to manage; In addition, in the early stage of the construction of the sewage treatment plant, the construction of the corresponding supporting pipe network is required. The construction fee of the pipe network is generally not lower than the construction fee of a sewage treatment plant supporting the pipe network. For rural areas, it is relatively remote and scattered. Part of the pipeline network construction fee investment will be very large. [0003] The disadvantages of the current urban sewage treatment system are: ...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the current urban sewage treatment system are: the problem of sludge bulking is prone to occur. According to statistics, nearly 80% of urban sewage treatment plants have experienced sludge bulking. Once sludge bulking occurs, the quality of effluent water will deteriorate; sludge The concentration is limited and the volume load is not high, resulting in a large area, and the sludge return device is required, and the operating cost is relatively high; the normal operation of the process requires personnel with professional knowledge to manage, and the maintenance is large; the initial stage of construction requires capital investment The investment cost is high for the construction of the pipe network; it cannot be moved, and the wastewater can only be introduced into the sewage treatment plant through the pipe network; the treatment scale is large, and it is not suitable for the reality that rural areas are relatively scattered and the water volume is small
