三段式處理水長期循環利用對生長豬之影響

本試驗採用平均體重45 kg之肉豬36頭，分別以經三段式糞尿處理系統處理後之處理水（豬場處理水不排放每日新增加分娩舍及健康不佳之豬隻，沖洗豬舍用水，定時抽取厭氣及曝氣槽污泥）及以一般之地下水對照組，作水浴及豬舍沖洗用，飼養至110 kg後觀察其對豬隻生長之影響，結果顯示兩組之間豬隻生長性能沒有差異；水浴前地下水與處理水總生菌數含量分別為2.0×10^2～7.0×10^4 cfu/mL與9.0×10^2～2.9×10^5 cfu/mL，水浴後分別增加1.6×10^3～1.5×10^5倍與8.3×10^2～9.7×10^4倍；水浴前兩組用水均未測出大腸桿菌，但水浴後處理水含量為地下水之1.07～3.25倍，至於水中沙門氏桿菌，水浴前、後均未測出。呼吸及生殖道綜合感染症與沙門氏桿菌抗體力價測定均無任何症狀發生，顯示經三段式系統處理過之處理水能殺死寄生蟲及原蟲。經三段式廢水處理系統處理過之排放水經循環再利用供豬隻水浴，均能保持豬隻身體及豬舍乾淨，可以節省沖洗豬舍人力及水資源。

The objective of this study was to investigate the application of treated water from the three-step system on the pig growth performance and the health. Thirty six pigs with average body weight of 45 kg, were divided into two groups. One was treated group which used the treated water and the other was control group which used ground water for water bathing and washing pig pen. Pigs were raised to the body weight of 110 kg to see if there were any difference on growth performance and health between the two group pigs. The results showed that there was no significant difference in growth performance of pigs between two groups. The total bacteria plate counts before water bath were 2.0×10^2 - 7.0×10^4/CFU/mL and 9.0×10^2 - 2.9×10^5/CFU/mL for the control and the treated groups respectively. After water bath, the total bacteria counts increased 1.6×10^3 -1.5×10^5 and 8.3×10^2 - 9.7×10^4 times of those before water bath. The E. Coli was not found before the bathing. It increased 1.07~3.25 times for the treated and control groups than before bathing. Salmonella was not found before and after water bath. On the antibody virulence test for salmonella and PRRS, no syndrome of swine salmonella or PRRS, were observed. The result indicated that parasites and protozoa could be killed during anaerobic treatment step. Recycling use of the treated water from water bathing and pigpen washing was a water saving method to keep the pigs clean.
