The invention relates to a funnel channel for separating suspended substances in water fish culture wastewater, which belongs to the technical field of aquaculture wastewater treatment. The present invention is mainly to solve the technical problems of low separation efficiency, high energy consumption and high operating cost of the existing drum microfiltration machine for treating water culture wastewater. The technical scheme of the invention is as follows: a funnel water channel for separating suspended matter in water raising fish wastewater, which includes a sewage collecting channel, a number of precipitating funnels, a number of sewage pipes, a number of discharge valves and a total sewage pipe. The precipitating funnel is vertically located at the bottom of the sewage collecting channel along the channel, and the sewage pipe is set up. The end of the pollution channel is connected with the outlet of the precipitating funnel, and the other end of the sewage pipe is connected with the total sewage pipe, and the discharge valve is installed on the sewage pipe, and the total discharge pipe is located on the side of the bottom of the sewage collecting channel. The invention has the advantages of large capacity for wastewater treatment, low construction cost and energy conservation.

一种分离流水养鱼废水中悬浮物的漏斗水渠
本专利技术涉及一种分离流水养鱼废水中悬浮物的漏斗水渠,它属于养殖废水处理
技术介绍
流水养鱼属于高密度养殖,由于饲料投喂产生大量的粪便及残饵等悬浮物和流水养殖水交换量大,养殖废水的处理难度大,一般养殖废水采取直接排放,严重影响水环境。为了有效处理流水养殖废水,目前工厂化循环养殖废水一般采用滚筒微滤机过滤流水养殖废水,原理是将养殖废水通过管道输送到机械带动的滚筒滤网中使悬浮物与水分离,实现鱼类粪便和残饵与水体分离的目的。滚筒微滤机处理流水养殖废水存在的技术问题是:一、分离效率低,最大处理量仅为350立方米/小时,不能满足流水养殖的需求;二、需要消耗电能,增加运行成本;三、设备价格贵,每台设备7万元,且需要进行定期维修,在维修期间影响废水的处理。
技术实现思路
本专利技术的目的是解决现有滚筒微滤机处理流水养殖废水存在的分离效率低、消耗电能大和设备运行成本高的技术问题,提供一种建造简单、建设成本低、不需要消耗能源和运行成本低的分离流水养鱼废水中悬浮物的漏斗水渠。为解决上述技术问题,本专利技术采用的技术方案是:一种分离流水养鱼废水中悬浮物的漏斗水渠,它包括集污渠道、若干沉淀漏斗、若干排污管道、若干排污阀门和总排污管道,所述若干沉淀漏斗沿集污渠道纵向均匀设在集污渠道的底部,所述排污管道设在集污渠道的底面其一端与沉淀漏斗的出口连接,所述排污管道的另一端与总排污管道连接,所述排污阀门装在排污管道上,所述总排污管道设在集污渠道底部的一边。进一步地,所述漏斗水渠还包括若干生物浮床,所述若干生物浮床设在集污渠道中并浮在水上。进一步 ...
