Aquaculture Filter Media Bio Filter For Ras
Product describe：
Aquaculture Filter Media Bio Filter For Ras The invention provides a moving bed biofilm reactor, including chestnut 4 and MBBR reactor 3. The water chestnut in the sewage tank into the MBBR reactor, MBBR start water inlet mass concentration is low, the reactor air chestnut 4 is connected with the aeration device, the aeration device 2 and 3 are respectively arranged in the middle and bottom of the reactor, the aeration volume is adjusted to make the filler just complete fluidization. The biofilm on the filler is very thin in the early stage of treatment, which requires a large energy consumption for fluidization and a long hydraulic retention time at the beginning, so the gas-water ratio is as high as 25:1. With the increase of inlet water flow, the hydraulic retention time becomes shorter and the biofilm on the packing becomes thicker. At this time, the energy consumption of complete fluidization of the packing becomes smaller, and the gas-water ratio is about 10:1-15:10
[0007] When the MBBR reactor is started, the biological filler needs to be membrane hung. At the beginning, the closed cycle method was adopted. After the inoculation sludge was put in, the aeration was conducted for 24 h to make the sludge and the filler fully contact, and then the inoculated activated sludge was discharged, and then the prepared wastewater was continuously put in. At first, the mass concentration of wastewater was low, about 120 mg/L, and the flow rate was 5 mL/min. Then, the influent flow rate was gradually increased to improve the organic load, and finally the mass concentration of suspended sludge was between 2 000 ~ 5 000 mg/L.
[0008] The water outlet of the reactor is connected with the sedimentation tank pipeline. The sedimentation tank 5 is connected with the anaerobic tank 6 and the aerobic tank 7 respectively through the water chestnut. The aeration device 9 is set in the aerobic tank and the anaerobic tank respectively, and the aeration device is started through the air chestnut 8. By setting up aerobic and anoxic environments, and by internal circulation reflux, the "pre-positioned denitrification system" can achieve the purpose of removing organic matter and nitrogen. The spillage of the aerobic tank directly discharges the treated water.
Product Advantage:
1.Minimum Area required
2.Less manual intervention
3.Nominal price
4.Easy to handle and Easy to stabilize
5.Minimum sludge production
6.Lower sludge production
7.High efficiency and performance
8.Bod and Cod reduced to greater extend
Aquasust MBBR:
Aquaculture Filter Media Bio Filter For Ras The process is suitable for meat processing wastewater, high concentration organic wastewater, landfill leachate and other high-load sewage, while for domestic sewage with low concentration of organic matter, the water quality index of the treated effluent can reach the national reuse index.
1, impact load resistance, long mud age, less residual sludge, high efficiency and flexible operation.
2, the reactor sludge concentration is high, the general sludge concentration is 5~10 times of the common activated sludge method sludge concentration, the aeration tank sludge mass concentration can be as high as 30~40g/L.
3, the head loss is small, not blocking, no backwashing, generally no backflow.
4. As the core of MBBR process, the suspended filler has aerobic and anaerobic metabolic activities and can remove nitrogen and phosphorus well.
