What are the common technologies for rural sewage treatment? Ask god for advice.

You can refer to the following technologies:

"BIOFORM biological purification technology" is the core. Through primary filtration and sedimentation, biological purification, physical adsorption, nano-materials and ultraviolet disinfection, the water quality can reach the clean and healthy water use standard. In the process of biological purification, BIOFORM microbial inoculum, relying on the dual patented technology of "bacteria+enzyme" and "microcapsule packaging", can degrade pollutants in water efficiently.

The schematic diagram of the project is as follows
