| 内容記述 | The purpose of this study was to clarify the effects of a mixing intensity on the quality of treated water and the recovery of fertilizers when N, P, and K were simultaneously recovered from swine wastewater at high pH using a batch recovery system. Experiments were performed using a batch reactor. A sedimentation velocity was almost constant at a mixing intensity from 20 to 70 sec⁻¹, but the sedimentation velocity decreased at a mixing intensity over 70 sec⁻¹. The maximu of SS concentration as small as 120 mg/L indifated that the solid-liquid separation was sufficient. At a mixing intensity of 31 sec -1 or less, the total concentrations of P and N in the treated water satisfied the Effluent Standars. The N, K, and P contents of the air-dried product satisfied the minimum required for mixed animal excrement complex fertilizer. The recovery rate of N as fertilizer increased but recovery rate of K as fertilizer decreased with increase in mixing intensity. The average recovery of the sum of N and K was maximum (92%) at a mixing intensity of 31 sec⁻¹. The recovery rate of P as fertilizer was 100% at any mixing intensity. From the viewpoints of both water treatment and resource recovery, the optimum mixing intensity was 31 sec-1. | |||||||||||||||||
