An underground integrated rural domestic sewage treatment device

Abstract

The invention discloses a buried integrated rural domestic sewage treatment device, a buried integrated rural domestic sewage treatment device, comprising a buried body, the top of which is provided with a driving device and a delay device The loofah is fixed through the cooperation of tensioning device, lifting device and purification device, which avoids the problem of local filler accumulation and blockage, and periodically through the cooperation of lifting device, driving device, delay device, strain device and transmission device Drive the purification device to run, so that the loofah enters the activated sludge one by one and hangs the film again, avoiding the gradual aging of the biofilm on the loofah during use, which is easy to fall off from the loofah, resulting in the gradual deterioration of the purification effect of the loofah Poor problem, through the cooperation of the buried body, tensioning device, lifting device, driving device, and purification device, it is convenient for people to replace the loofah, saving time and effort, and improving the efficiency of the buried integrated rural domestic sewage treatment device. practicality.

Description

technical field [0001] The invention relates to the field of rural domestic sewage treatment devices, and more specifically relates to an underground integrated rural domestic sewage treatment device. Background technique [0002] Rural areas are also called rural areas. The areas where the agricultural population is mainly engaged in agricultural production have preserved the original landscape of nature and have specific socio-economic conditions. In the environment, a pastoral scene is formed; the phenomenon of family settlements is more obvious; the development level of industry, commerce, finance, culture, education, and health services is low. The sewage generated in the life process of rural people is called rural domestic sewage, which has the characteristics of small discharge and large fluctuation. According to the above-mentioned characteristics of rural domestic sewage, people design and manufacture a variety of buried integrated rural domestic sewage treatment d...

Problems solved by technology

[0003] However, the membrane module in the SBR reactor is expensive and the maintenance cost is usually high, resulting in high sewage treatment costs and low economic benefits; the carrier filler filled in the SBBR reactor is in a fluidized state relying on aeration and water flow. In actual engineering, it is easy to have local filler accumulation, which will lead to a reduction in economic benefits, and the outlet of the SBBR reactor is often equipped with grids or grids to avoid the loss of filler, which is easy to cause blockage, resulting in low sewage treatment efficiency. At the same time The biofilm on the carrier filler gradually ages during use. The aging biofilm has poor purification ability and is easy to fall off from the carrier filler, which leads to the gradual deterioration of the purification effect of the filled carrier filler. The carrier filler needs to be replaced, and the replacement method is more complicated. , time-consuming and labor-intensive, so it is urgent to design a buried integrated rural domestic sewage treatment device
