Common domestic sewage treatment processes in rural areas include "A/0+ constructed wetland" and "aerated biological filter" . The "A/0+ constructed wetland" process requires the construction of secondary sedimentation tanks and constructed wetlands. It occupies a large area and the activated sludge in the system is easily disintegrated during operation. When there is insufficient water, the soil in the constructed wetland will become compacted and blocked, affecting the quality of the effluent water. The "aerated biological filter" process occupies a relatively small area. However, there are also problems such as water resistance, weak impact ability, and easy clogging.
 


In order to solve the clogging problem, this process requires the addition of backwash equipment in the system. The power consumption and subsequent operation and maintenance costs are high.And backwashing will wash away part of the sludge, affecting the quality of the effluent water. Aiming at the pain points and difficulties such as large footprint, weak impact resistance, easy clogging, and high cost. Qingyan Environment devoted itself to research and development and launched the "T-Bic Biological Purification Pool"
 
"T-Bic" is three-dimensional immobilized biological curtain technology, Qingyan Environment has integrated T-Bic technology equipment into "T-Bic module”, then it forms the "T-Bic biological evolution pool" . The integrated aeration system at the bottom forms a circulation around the biological curtain. Effectively improve mass transfer efficiency and enhance processing capacity. The top of the module can also be equipped with optional emergent landscape plants. The entire system can be powered by photovoltaic power without any electricity cost. It truly solves the pain points and difficulties that have long plagued rural sewage treatment.
