“…After this, enhanced H+ exchange promoted the release of nutrients from the phytolith ash. This indicates the different responses of phytoliths and the nutrients they absorb to CO2, and provides better insights into the fate of soil phytoliths and trends in the nutrient budget of straw phytoliths in soils [4]. Porte H evaluated process performance and determined the microbial community structure of two laboratory-scale, thermophilic trickle-flow biofilter reactors for the biomethanation of hydrogen and carbon dioxide for a total of 94 days.…”

In today's world, due to industrial and agricultural development, population explosion, water abuse and pollution, the water crisis caused by water shortage and water pollution has become a complex problem faced by most countries in terms of policy, economy and society. As a new type of wastewater treatment process, biological filter has been widely used at home and abroad. The purpose of this work is to study the characteristics of starting the hanging film culture after the advanced treatment of urban sewage sludge by aerated biological up-flow filter. By changing the ammonia nitrogen concentration, hydraulic retention time and filter material filling height, the treatment efficiency of the aerated biological filter was studied, and the optimal process operating conditions were determined and optimized. Using aerated biological up-flow filter to treat sewage sludge in M city, the COD removal rate is the lowest 30%, the highest removal rate is 47%; the turbidity removal results show that the highest removal rate is 92%, and the lower removal rate is 71%.
