Abstract

The triphase sludge-water separating apparatus for high concentration industrial effluent treatment consists of triphase separators. Several triphase separators are connected serially through connecting plates into one group, several groups are connected serially with trapezoidal holding plates to form one layer; and several layers are arranged staggered and arranged. The triphase sludge-water separating apparatus is provided with also marsh gas collecting pipes, marsh gas conveying pipes and sealing end boards. The present invention has high sludge-water separating effect and no water flow shorting.

Description

technical field [0001] The invention relates to a high-concentration industrial wastewater treatment device, especially a three-phase separation device for mud, water and gas. Background technique [0002] The three-phase separation method is a key technology of the high-efficiency anaerobic process, and its working performance directly affects the total amount of effective microorganisms that can be intercepted in the reactor, thereby affecting the treatment effect of the anaerobic process. The traditional three-phase separation method currently used in domestic treatment projects, due to defects in design, often occurs that the return sludge and the rising water share the same channel, which interferes with the sedimentation effect of the sludge; or the rising water carries anaerobic The short-flow phenomenon that the sludge directly enters the effluent system through the three-phase separation zone causes a large amount of highly active anaerobic sludge to be lost with th...
