滤料浮床面积对水产养殖水体的原位修复效果
|
摘要
构建了适用于水产养殖水体原位修复的滤料浮床生态调控系统,考察了不同床水比(浮床面积与水体面积比)条件下的水产养殖水体原位修复效果。结果表明,当床水比为1∶10时,试验周期内的化学需氧量(CODMn)、NH3-N和溶解氧(DO)分别维持在20、0.07和6.5 mg/L左右,鱼苗的成活率和增重率比无浮床系统分别提高了13%和25%;床水比为1∶15时,净化能力不足,水质指标逐渐恶化;床水比为1∶5时,布水装置启动频繁,减缓鱼苗的生长速度。
A kind of ecological regulation and control system of floating bed used for in-situ remediation for aquaculture water body was constructed. The effects of in situ remediation under conditions with different bed and water ratio were investigated. The results showed that,when the area of bed and water ratio was 1∶10,CODMn,NH3-N and DO were maintained at 20mg/L,0.07 mg/L and 6.5 mg/L respectively in the experimental period. Compared with non floating bed system,the survival rate and the growth rate of fries in floating bed system increased by 13% and 25% respectively. When the area of bed and water ratio was 1∶15,the purification capacity was insufficient,and the water quality was gradually deteriorated. When the area of bed and water ratio was 1∶5,the water distribution device was frequently started, and the growth rate of fries was slowed down.
