[0039] 从工厂化养殖车间中排出的废水由进水管 11进入筛网固液分离器 1, 形成旋流 1 5, 清水通过筛网 12过滤流出, 进入清水槽 2, 由清水槽 2的出水口 21流出, 筛网 的网目为 80-120目; 固态废物 14则随着旋流下沉, 沉积在椎体底部。 椎体底部与 外置的固态废物沉淀池 3由底部管道 4相连, 固态废物沉淀池 3内装有柱状筛网集 污器 31, 固态废物沉淀池 3的净水区 32设置低扬程水泵 34, 低扬程水泵 34与筛网 清洗喷头 13连接。 抽水时, 筛网固液分离器 1的椎体底部与固态废物沉淀池 3的 流水经过柱状筛网集污器 31过滤, 进入固态废物沉淀池 3的净水区, 从而, 持续 不断地喷水清洗筛网 12, 并带动椎体底部的污物移向固态废物沉淀池 3 , 并滞留 在沉淀池的柱状筛网集污器 31。 每天开启置于柱状筛网集污器 31内的污泥泵 35 , 将污泥排出。 污泥由污泥泵 35进入有机肥发酵池 5 , 与秸秆搅拌, 发酵成有机 肥。
[0040] 多年的应用测试数据表明, 本发明的固液分离器对工厂化水产养殖废水的分离 净化作用十分显著。 直径为 4米, 筛网面积为 2.8平方米的固液分离器, 每小时流 入 800立方畜禽养殖废水, 处理前, BOD 12.1 mg /L, 分离后的 BOD下降到 0.25 mg /L; 可见, 本发明的固液分离器可有效分离工厂化水产养殖废水中固态废物 , 流量较大, 堵塞较少, 无需更换筛网框, 日常维护简便易行。 [0041] 上述实施例因理解为仅用于说明本发明而不用于限制本发明的保护范围。 在阅 读了本发明记载的内容之后, 本领域技术人员可以对本发明作各种改动或修改 , 这些等效变化和修饰同样落入本发明权利要求所限定的范围。
