北京市规模化畜禽养殖场粪便和污水监测及承载力估算
Monitoring and Carrying Capacity Estimation of Animal Manure and Wastewater in Beijing Livestock Farm
摘要
Abstract
The research aimed to study the current situation of livestock environmental pollution in Beijing.The animal manure and wastewater from 36 livestock farms in 9 districts of Beijing were collected and investigated in 2016.The investigation was assessed by single pollution index and equal standard pollution load,and the carrying capacity of animal manure and wastewater in Beijing was estimated by nitrogen and phosphorus balance theory.Results show fecal coliform was the major pollution index in animal manure and wastewater.The pollution intensity of the other pollution index in wastewater:suspended matter>BOD5 > CODcr > ammonia nitrogen.Pollution load ratio for pig farm wastewater and cattle farm wastewater was 5.1.The pig farm wastewater was the major wastewater type in livestock farm.The heavy metal pollution of pig manure in animal manure was the most serious,Cu and Zn exceeded the standard rate by 70% in pig manure,the chicken dung ranked the second,with exceeding rate of 46%.The metal pollution of cattle dung was not obvious;It is estimated that the nutrient emission from livestock manure and wastewater only accounted for 70.5% of the land carrying capacity (take the N),53.0% (take the P) in that year,and the arable land in Beijing was able to carry the livestock manure and wastewater of 2016.The research could provide data support for policy formulation related to early warning of livestock environment.关键词
