禽畜粪便的处理是制约规模化、集约化饲养场发展的重要因素，处理得不好将会造成严重的环境污染，阻碍饲养业的发展。禽畜粪便的固液分离是禽畜粪便处理的重要手段；禽畜粪便的综合利用是提高经济效益、促进饲养业发展的有效途径。本文详细论述了禽畜粪便固液分离的方法和设备，其中，提出了经济有效的猪粪及鸡粪综合利用模式，并对今后的研究方向和发展趋势提出了作者的观点。
The handling of livestock excrement is an important factor restricting the development of large-scale and intensive breeding farms. Handling poorly will result in serious environmental pollution and hinder the development of breeding industry. The solid-liquid separation of livestock excrement is an important means of livestock excrement disposal. The comprehensive utilization of livestock excrement is an effective way to increase economic benefits and promote the development of livestock husbandry. This paper discusses in detail the methods and equipment for solid-liquid separation of livestock excrement, and puts forward the economical and effective mode of comprehensive utilization of pig manure and chicken manure and puts forward the author’s view on the future research direction and development trend.
