Specific implementation mode
A kind of buried under earth type sewage integrated treatment unit of the utility model is made shown in below in conjunction with the accompanying drawings further
Description.
Buried under earth type sewage integrated treatment unit as shown in Figure 1, including by 9 sequentially connected collecting pit of drainpipe
1, intermittent aeration pond 2, biological contact oxidation pond 3, sedimentation basin 4, sterilization pool 5 and MBR reaction tanks 6 are equipped with water on drainpipe 9
