<p>A method of producing liquid fertilizer from livestock excretion comprising a biological treatment and a separation membrane process is provided to perform a preprocessing and various biological treatments, to improve process efficiency and to produce a high quality of liquefied fertilizer by introducing a process processed by a turbulence type separation film and a spiral separation film. A livestock excretion is processed by an adulteration processor and a centrifugal dehydrator(S3). The livestock excretion passing through the preprocess is purified by a microbe removal mode by a biological treatment(S4). A liquefied fertilizer is produced(S8) by filtering and concentrating the processed water passing through the preprocessing and the main processing steps by a turbulence typed separating film device(S5,S6). The biological treatment includes an expiratory process.</p> |
