豬場糞尿對環境的影響

發布時間:2019-04-12 15:22:49 瀏覽:279次

采用牲畜環保設備,像是固液分離機,糞便發酵機等,養殖場空氣也能清新,還可以將糞便變廢為寶,更加合理利用。豬場產生的污水、糞渣及惡臭氣體等對四周水體、大氣、泥土、人體健康及生態環境會造成直接或間接的影響。因此,無公害生豬生產中,要充分考慮豬場沾染物處理設施,不容許豬糞污未經任何處理即就地排放,或將豬糞便長期就近堆置跟排放到鄰近環境,造成蚊蠅滋生,沾染水體跟空氣。豬場含有大量有機物跟氮、磷養分元素的污水流入河流跟湖泊,造成水體富養分化;浸透地下,使地下水中氮化物、硬度跟細菌總數超標。據測定,一個年產10萬頭的豬場,每小時可向大氣排放159千克氨、14.5千克硫化氫、25.9千克粉塵跟15億個菌體,這些物質的沾染半徑可達4.5~5千米。
