思南县有近8万个畜禽养殖场,饲养的主要畜禽品种有猪、牛、羊、禽等,传统的深坑湿圈、熟饲料喂猪牛等饲养方式占主导地位。饲养畜禽产生的粪便直接排到粪池,春天雨水多的时候,粪池内的污水溢出,到处流淌;夏天产生大量的蚊虫、苍蝇,严重影响了畜禽生长和周围的环境。笔者就思南县农村畜禽养殖业的污染问题进行了系统分析,提出了农村养殖业防污治污的办法及措施,供广大同行参考。
There are nearly 80,000 livestock and poultry farms in Sinan County. The main livestock breeds are pigs, cattle, sheep and poultry. The traditional deep-pit wet circles and cooked feed are the main ways to feed pigs and cattle. Feces produced by livestock and poultry are discharged directly to the septic tank. In spring when the rain is abundant, sewage in the septic tank overflows and flows around. Large amounts of mosquitoes and flies in the summer have seriously affected the growth of livestock and poultry and the surrounding environment. The author of Sinan County, rural livestock and poultry breeding pollution in the system were analyzed and put forward the rural aquaculture anti-pollution methods and measures for the general counterparts for reference.
