【摘要】：畜禽養(yǎng)殖業(yè)污染是環(huán)境污染的主要來源之一。農(nóng)牧結合被認為是解決畜禽養(yǎng)殖業(yè)污染的有效途徑,但是規(guī)模化畜禽養(yǎng)殖使得我國畜禽糞便排放密度增加,配套耕地卻沒有隨之同比增加,配套土地規(guī)模與養(yǎng)殖規(guī)模不匹配的矛盾制約了農(nóng)牧結合治污效果的發(fā)揮�；趯幽鲜�23家生豬養(yǎng)殖企業(yè)和1處養(yǎng)殖集中區(qū)的實地調(diào)研,研究發(fā)現(xiàn),根據(jù)匹配土地規(guī)模,選擇不同的畜禽糞污處理模式是解決該矛盾較為現(xiàn)實的路徑。在生豬糞污處理過程中,對于固體糞便的處理較為單一,而對于污水處理模式的差異較大。污水處理的能耗和環(huán)境的影響均最大,是糞污處理過程中的難點和重點。
[Abstract]:Livestock and poultry industry pollution is one of the main sources of environmental pollution. The combination of agriculture and animal husbandry is considered to be an effective way to solve the pollution of livestock and poultry breeding, but large-scale livestock and poultry breeding increases the emission density of livestock and poultry faeces in China, but the supporting cultivated land does not increase year-on-year. The contradiction between the scale of supporting land and the scale of breeding restricts the effect of combining agriculture and animal husbandry. Based on the field investigation of 23 pig breeding enterprises and 1 breeding concentration area in Henan Province, it is found that according to the matching land scale, the choice of different livestock and poultry manure treatment models is a more realistic way to solve this contradiction. In the process of pig manure treatment, the treatment of solid feces is relatively simple, but the sewage treatment mode is quite different. The energy consumption and environment of sewage treatment have the greatest influence, which is the difficulty and key point in the process of sewage treatment.
