The heavy mud chosen in certain Running-water Company's spent filter backwash water carries out mud sample collection, through laboratory separation screening
The bacterial strain that can be used for microorganism demanganization obtaining sends out iron bacteria (clonothrix), crenothrix polyspora (crenothrix for withe
Fusca), sheath iron bacteria (sidero capsa), fine iron bacteria (leptothrix), good formula handspike bacillus
Etc. (gallionella) 5 kinds of bacterial strains are dominant strain.
(2) the domestication culture of bacterial strain
Culture is tamed using solid medium: 1. activation processing is carried out to bacterial strain；2. according to sewage: bacteria domestication liquid is 1:
The domestication liquid that 10 volume ratio prepares each antibacterial (takes sewage 10ml to put into conical flask, is then placed in 90ml inoculum, mix
Synthesis 100ml antibacterial culturing domestication liquid), and prepare identical and be not added with the mixed-culture medium of bacterium solution as reference；3. add 2g fine jade
Fat, mix homogeneously；4. the domestication preparing culture fluid is placed on sterilizing in pressure cooker, cools down after sterilizing；5. on aseptic platform all
Even be potted in 5 culture dishs, to be cooled formation solid medium after, add 0.8ml bacterial strain；6. the culture dish transferred is put
Enter calorstat to cultivate at 26 DEG C, and observe bacterium colony in culture medium daily to be formed, record the time being formed required for bacterium colony.Progressively
Tame to success, the tamed strain time is 15 days.
(3) preparation of bacterium solution
Being formulated in cultivation groove 13 of bacterium solution is carried out, put in culture tank 1/3 volume to take from Running-water Company filter tank anti-
Mud in flushing water and the nutrient substance such as a little washing water of rice, Sanguis sus domestica, Testa Tritici, distiller grains, and the strain in Laboratory Acclimation is turned
It is connected in cultivation groove, opens low-speed mixer 13-1, motor speed is 60r/mim, control 20～30 DEG C of water temperature, ph value 6.5～
7.3, dissolved oxygen do≤2mg/l, sludge concentration is 4g/l, stirs 6～8 hours daily, through the culture of 6～7 days, liquid became
Yellowish red color bacterium solution is prepared successfully.
(4) filtrate biofilm, debugging and operation in microorganism demanganization pond
Biofilm adopts dominant bacteria biofilm method.Add certain tap water that moisture content is 98% to microorganism demanganization pond first public
Department's filter back washing muddy water, floods to filtrate top；Import micro- life by the 1/6 of muddy water amount by preparing successful bacterium solution in cultivation groove
Thing demanganization pond, is then shut off import and export valve (can not entering), opens the slit aeration flexible pipe 12-1 aeration at the bottom of pond portion, controls
Dissolved oxygen do, to 4～5mg/l, carries out vexed exposure 24 hours；It is then turned on import and export valve, microorganism demanganization pond starts to intake, water inlet
Pipe is gradually increased from small to large, becomes yellowish red color gluing shape on the time of 15 days, microorganism demanganization pond manganese sand filtering material, shows to filter
Biofilm success on material.
After debugging, control: 1. filtrate 8～10m/h；2. 24h filter cycle, backwashing time 10～12min, recoil
Wash intensity 14～16l/ (s)；3. ph value 6.5～7.3；4. dissolved oxygen do≤4～5mg/l；5. temperature is 20～30 DEG C, that is,
Normal operation can be proceeded to.Manganese sand filtering material series dominant bacteria after culture success for the described microorganism filter for manganese removal specifically includes that
clonothrix、crenothrix fusca、sidero capsa、leptothrix、gallionella、crenothrix、
Manganifera, sphaerotilus, pseudomonas, melallogenium and some funguses.
