This study has investigated the effect of humus soil activated sludge on the nitrogen and phosphorus removal. The results from experiments indicate that humus soil SBR (HS-SBR) process did not have a better effect on the COD removal compared it with SBR process. They had about 89% removal efficiency on average. HS-SBR process could enhance the removal of nutrient salt, especially TP. The removal efficiency...
Humus soil activated sludge (HSAS) process and conventional activated sludge (CAS) process of 400 L/day capacity were set up in lab to evaluate their performance. This study mainly focused on testing Nitrogen and phosphorus removal efficiency and settleability and dewaterability of sludge. The research shows that HSAS process could enhance the removal of nutrient salt, especially TP. It enhanced NH...
