近几年,畜禽养殖业快速发展,畜禽粪尿大量排放,给污染治理带来了新的课题。传统的物理处理和化学处理法成本高、效率低,且容易造成二次污染。沼气工程处理畜禽粪尿不但成本低、效率高,无二次污染,而且能收到综合利用的效果,实现畜禽养殖场污染治理“减量化、无害化、资源化”的目标,但要将这一工程利用好、发展好,实现环保、经济和社会效益长期化,还需要地方政府和各级职能部门支持、引导和管理。
In recent years, the rapid development of livestock and poultry breeding industry, livestock and poultry excretion of large amounts of emissions, pollution control has brought a new topic. The traditional physical treatment and chemical treatment of high cost, low efficiency, and easily lead to secondary pollution. Biogas project to deal with livestock and poultry excrement not only low cost, high efficiency, no secondary pollution, but also to receive the effect of comprehensive utilization of livestock and poultry farms to achieve pollution control “reduction, detoxification, recycling”. However, if we make good use of this project and develop it well to achieve long-term environmental, economic and social benefits, we also need the support, guidance and management of local governments and functional departments at all levels.
