Background technology
In closed industrial circulating water cultivating system building process, biofilter is core link。In circulating water culture system, cultivation object is had very big toxicity by ammonia nitrogen, accumulating of cultured water, and mineralized nitrogen can be become nitrite by the nitrobacteria in biofilter, and then changes into nontoxic nitrate。Therefore, how to maintain the efficient Nitrification in biofilter it is critical that。
Common biofilter, especially fixes bed biofilter and is primarily present problems with:
1, the attachment long term accumulation such as Organic substance and other particulate matter above biologic packing material causes the problem that biological filter membrane is difficult to form even bacteria bed " collapse ", it is necessary to human at periodic intervals is carried out taking time and effort；During cleaning, system then cannot run well；
2, the purifying water micrcxDrganism that biologic packing material surface grows is often because aging coming off is deposited on bottom biofilter, causes and becomes current " dead angle " bottom biofilter, have impact on water treatment efficiency；Long term accumulation also there will be anaerobic fermentation, produces the noxious substances such as more ammonia nitrogen；
3, need to increase external nitrobacteria artificially, maintain nitrobacteria quantity；External nitrobacteria is difficult in adapt to current water quality, and instability, purification efficiency are poor；
4, lacking water body pH regulator device in biofilter, enter the breeding water body of biofilter containing high concentration CO 2, water body presents acidity, and the pH of its nitrobacteria the best nitration reaction is meta-alkalescence, is substantially reduced the reaction rate of nitrobacteria。
At present, in the industrial circulating water cultivating system of home and abroad, due to the consideration of construction cost and technique, fixing bed biofilter is the important component part of system constructing。But, the research certainly safeguarding security system of biofilter in industrial circulating water healthy breading system, apply less。Wherein, authorize patent of invention (application number: 201110319978.0) described automatic maintenance inoculation-free method for biological filter of circulating water culture system and special purpose device thereof, though structural design is simple, but only by the backflow of simple pipeline, only by the flowing of biofilter surface water, exchange, it is difficult to realize nitrobacteria quantity and maintain and purify the efficient of activity；Also the activity of nitrobacteria has the external carbon sources such as the increase glucose artificial in biofilter of researcher, though can be increased the short time；But, glucose is that stickum also can block the solarization air cap on bottom inflow pipe and circulating water pipeline。
