At this time, the concentration of the adsorbed substance in the solution is called equilibrium concentration.In aerobic part, a self-made internal circulating biological fluidized bed reactor was used to treat organic pesticide wastewaterThe effects of internal circulating biological fluidized bed on the removal of organic matter and the deamination of organic pesticide wastewater, the change of wastewater biodegradability and acute biological toxicity were investigated.The results show that the internal circulation biological fluidized bed with granular activated carbon as the carrier has a fast speed of membrane and can be cultured in about days by the rapid sludge drainage methodOut of activated sludge.The internal circulating biological fluidized bed with granular activated carbon as the carrier is not sensitive to temperature change at 1 ℃, and has a certain impact resistance ability.Aeration amount has effect on the treatmentToo large or too small aeration will reduce the reactor treatment efficiency.The optimal hydraulic retention time of the internal circulating biological fluidized bed using granular activated carbon as carrier is, and the treatment effect will be affected if the hydraulic retention time is too long or too short.
At the aeration rate of /,During hydraulic retention, the total helium removal rate is.%,.%, water effluent/up tothe biodegradability of wastewater was significantly improved, and the acute biological toxicity was reduced by b4_When the efficiency of internal circulating activated carbon biological fluidized bed treatment is.%, the reaction is obtainedAt present, China consumes 250 million MR of wood annually, and imports 3 billion US dollars of wood and forest products annually to make up for the shortage.In order to ensure the fundamental interests of China's forestry enterprises, extend the industrial chain of wood processing products, and promote the development of China's timber industry to the efficient utilization of wood based on the deep processing of products and the comprehensive utilization of raw materials, it has become the pursuit of China's forestry industry
