随着畜禽养殖业的发展,畜禽养殖排泄污染已成为当前继工业污染、生活垃圾污染之后的第三大污染源。多年的实践表明,以厌氧消化技术为主体的沼气工程是治理畜禽排泄物污染的有效途径。根据对污水处理程度的不同,沼气工程可分为“能源生态型”和“能源环保型”两类,目前应用的沼气工程主要以“能源生态型”为主。“能
With the development of livestock and poultry breeding industry, livestock and poultry excretion and pollution have become the third largest source of pollution after industrial pollution and domestic garbage pollution. Years of practice shows that the biogas project that takes anaerobic digestion technology as the main body is an effective way to control the livestock and poultry excrement pollution. According to the different degree of sewage treatment, biogas projects can be divided into two categories: ”energy eco-type“ and ”energy eco-friendly type.“ Currently, biogas projects are mainly used for ”energy eco-type“. ”can
