In the present invention, by passing into air or oxygen by inlet pipe and escape pipe between the microbial film be parallel to each other, like this, biomembranous both sides are respectively oxygen side and reaction side, this situation can from the duration of contact of oxygen and film and contact area two aspects, being convenient to oxygen is passed in membranous system, is beneficial to and improves oxygen transfer efficiency to improve sewage treatment capacity; Meanwhile, due to compared to traditional bubble aeration structure, due to oxygen and biofilm contact area certain, the present invention also has the advantage being convenient to control sewage treatment process parameter.The impeller arranged to be used for for liquid carrying in reaction tank for power to strengthen the flowing of liquid in described pond, is beneficial to fully contacting of liquid and bio-reactor in reaction tank, is beneficial to raising processing efficiency of the present invention.
Further technical scheme is:
For making the sewage entering into reaction tank effectively to contact with bio-reactor, also comprise and be arranged on water inlet pipe on reaction tank sidewall and rising pipe, described water inlet pipe is positioned at the below of bio-reactor, and described rising pipe is positioned at the top of bio-reactor.
Can flow uniformly in reaction tank for realizing sewage, being beneficial to organic clearance, all more than one of described water inlet pipe and rising pipe.
For ease of the discharge of mud in reaction tank, the bottom of described reaction tank is also provided with and drains mouth.
For improving the sewage treatment capacity of this reaction tank, described biological respinse group is many groups, and biological respinse group is stacked distribution on the depth direction of reaction tank, and often the spacing organized between biological respinse group is not more than 15cm.
For the defect that the process reducing to cause because of sludge settling is insufficient, described impeller is propeller pump, and the axis of described propeller pump is with respect to the horizontal plane inclined to set.The power of above impeller is beneficial to and reduces or avoid sludge settling.
The present invention has following beneficial effect:
1, by passing into air or oxygen by inlet pipe and escape pipe between the microbial film be parallel to each other, like this, biomembranous both sides are respectively oxygen side and reaction side, this situation can from the duration of contact of oxygen and film and contact area two aspects, being convenient to oxygen is passed in membranous system, is beneficial to and improves oxygen transfer efficiency to improve sewage treatment capacity; Meanwhile, due to compared to traditional bubble aeration structure, due to oxygen and biofilm contact area certain, the present invention also has the advantage being convenient to control sewage treatment process parameter.
2, the impeller arranged to be used for for liquid carrying in reaction tank for power to strengthen the flowing of liquid in described pond, is beneficial to fully contacting of liquid and bio-reactor in reaction tank, is beneficial to raising processing efficiency of the present invention.
