-
摘要:
近年来，河南省潢川县加大畜禽养殖污染治理力度，以种养结合、农牧循环、就近消纳和综合利用为主线，通过实施生猪调出大县、畜禽粪污资源化利用整县推进及绿色种养循环农业试点等项目，提高养殖场粪污处理设施配套率和综合利用水平，取得了显著成效。介绍了潢川县探索实践畜禽粪污厌氧发酵全量利用模式的成效，分析了当前存在问题，提出发展对策与建议，为畜禽粪污全量利用工作持续深入开展提供参考。
Abstract:In recent years, Huangchuan County has strengthened pollution control of livestock and poultry breeding, focusing on combination of planting and breeding, agriculture and animal husbandry cycle, nearby consumption, and comprehensive utilization．Through implementation of projects such as transfer of live pigs out of large counties, promotion of resource utilization of livestock and poultry manure throughout the county, and pilot of green planting and breeding circular agriculture, efforts have been made to improve matching rate and comprehensive utilization level of livestock and poultry manure treatment facilities, and remarkable results have been achieved．Exploration and practice of full utilization mode and results of anaerobic fermentation of livestock and poultry manure in Huangchuan County was introduced, current problems and suggestions were analyzed to provides reference for continuous and in-depth development of full utilization of livestock and poultry manure．
