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.
Employing microbial film is the vibrational power flow of hollow type assembly, is convenient to the kind and the quantity that are increased active bacterium colony on microbial film by the filler inside it, is conducive to the adaptive faculty strengthening sewage of the present invention like this.
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.
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, employing microbial film is the vibrational power flow of hollow type assembly, is convenient to the kind and the quantity that are increased active bacterium colony on microbial film by the filler inside it, is conducive to the adaptive faculty strengthening sewage of the present invention like this.
