  四、外贸出口MBR一体化污水处理设备的运行注意事项
  1、MBR系统是技术先进的污水处理设备，但对进水水质也有较为严格的要求。对于废水含有大量重金属、难生物降解的有机物、农药、油类、酸碱等污染物时，必须进行前处理，才能进入MBR系统进行处理。
  2、对于排水量间断、集中和水质变化较大的排污点，必须建调节池进行水量和水质调节，才能进入MBR系统进行处理。
  3、MBR系统要求连续运行，一旦停止曝气超过12小时，将导致维生物大量死亡，从而影响出水水质。
  4、膜组件需要进行周期清洗，才能维持MBR系统长期稳定运行，如果超过3-6个月不进行清洗，可能导致膜组件的永久性堵塞，无法恢复其功能。
  5、如果用户准备停止运行超过1周，应放空设备内污水，并注入清水浸没膜组件，膜组件必须完全浸没在清水中且在冰点上环境中存放，冬季时应考虑防冻，否则易造成设备和膜组件损坏。
  6、用户应建立定期检查和维护设备的制度，定期检查的内容包括：
  （1）格栅：定期清理栅渣，以免格栅堵塞影响进水；
  （2）出水真空压力表：定期检查并记录真空压力表情况，正常稳定运行的真空压力范围为0.01-0.04MPa；
  （3）出水水质和水量：定期测定进出水水质和水量并做好记录；
  （4）活性污泥状况：定期检查活性污泥的颜色，有条件的测定活性污泥的浓度；
  （5）设备其他部件的运行情况。

Compared with the existing technology, Shandong qiao enlightenment environmental protection equipment co., LTD. MBR integration of sewage treatment equipment adopted the "membrane integrated sewage purification technology" and "low energy consumption MBR sewage recycling new technology", overcome the traditional sewage treatment process has high energy consumption, long process, a large area, complex operation management, with compact structure, small area, low energy consumption, stable and reliable, high degree of automation, convenient maintenance operation advantages, can meet the demand of sewage treatment, in sewage treatment has great advantages.

1. Brief introduction of foreign export MBR integrated sewage treatment equipment

Membrane bioreactor (membrane bioreactor, MBR) water treatment technology is a kind of biotechnology and membrane technology combination of efficient biochemical water treatment technology, membrane bioreactor is combined with membrane separation technology and traditional sludge method of an efficient sewage treatment technology, due to the membrane filtration, biological is completely trapped in the bioreactor, realize the hydraulic stay time and sludge age thoroughly separation, make the bioreactor maintain high MLSS. Strong nitrification ability, high removal rate of pollutants.

Membrane bioreactor is a new water treatment technology combined with highly efficient membrane separation technology and activated sludge process. The application of hollow fiber membrane replaces the secondary sedimentation tank in the activated sludge method for solid-liquid separation, which effectively achieves the purpose of mud and water separation. Make full use of the membrane of efficient interception, can effectively intercept nitrifiers, completely retained in the biological reactor, the nitrification reaction ensure smooth, effectively remove ammonia nitrogen, avoid the loss of sludge, and can intercept a difficult degradation of macromolecular organic matter, prolong its stay in the reactor, make the maximum decomposition. After the application of MBR technology, the removal rate of major pollutants can be reached: COD 93%, SS=100%. The suspended matter and turbidity of water production are nearly zero, and the water quality after treatment is good and stable, which can be directly reused to realize the recycling of sewage.

2. Characteristics of foreign trade export MBR integrated sewage treatment equipment

Characteristics of the sewage treatment equipment using the MBR membrane bioreactor:

1. efficient removal of pollutants, can remove ammonia nitrogen and refractory organic matter, the treatment of effluent water quality is good;

2. High sludge concentration, low residual sludge production, large device volume load, and small footprint;

3. It is conducive to slow proliferation or efficient microorganisms, improve the nitrification effect of the system and the processing capacity of refractory organic matter;

4. High degree of automatic control completion, convenient operation and management;

5. The SS and turbidity of the discharged water after treatment are close to zero, and it can be reused by adding reclaimed water reuse equipment

6, the appearance of the equipment using steel structure, anti-corrosion paint, so the whole equipment is strong and durable, the life of up to more than 20 years;

7, wide application range of equipment, such as: urban sewage treatment and building water reuse, industrial wastewater treatment, micro-pollution drinking water purification, land landfill, fertilizer leachate treatment, fecal sewage treatment, etc.

3. MBR (Membrane bioreactor) process characteristics

1. Degrading organic matter in sewage, nitrification Nspan-N to NO3-, the removal rate of organic matter above 95%, and the removal rate of ammonia nitrogen above 97%.

2, the pretreatment process is simple, does not need to add a large number of chemical agents, the operation process is simple;

3, high recovery rate, the recovery rate of water can reach more than 99%, this flexibility allows operators to reduce the "pressure" on the diaphragm by reducing the recovery rate when the quality of the unpurified water deterior, but at the same time produce the same amount and quality of purified water;

4, the system uses a logical process monitoring system, including the flow transmitter and pressure transmitter and so on. This highly controlled system approach can be used to design flexible systems and improve the low requirements of operator interfaces;

7. The area is small, only 10~20% of the traditional process;

8. The use cycle is long, the continuous operation time can reach 70,000 hours, and the wire breaking rate is less than 1%.

4. Operation precautions of MBR integrated sewage treatment equipment

1. MBR system is an advanced sewage treatment equipment, but it also has strict requirements on incoming water quality. When the wastewater contains a large amount of heavy metals, difficult to biodegradable organic matter, pesticides, oils, acids and alkali pollutants, it must be pretreatment before entering the MBR system for treatment.

2. For the sewage discharge points with intermittent displacement, concentration and large water quality change, a regulating pool must be built for water quantity and water quality adjustment before entering the MBR system for treatment.

3. The MBR system requires continuous operation. Once the aeration is stopped for more than 12 hours, it will lead to a large number of vitamin biological deaths, thus affecting the effluent quality.

4. The membrane components need to be cleaned in cycle to maintain the long-term stable operation of MBR system. If it is not cleaned for more than 3-6 months, it may lead to permanent blockage of the membrane components and their function cannot be restored.

5. If the user is ready to stop operation for more than 1 week, the sewage in the equipment should be emptied and injected into the submerged membrane components. The membrane components must be completely immersed in clean water and stored in the freezing point environment. In winter, antifreeze should be considered, otherwise it is easy to cause damage to the equipment and membrane components.

6. Users shall establish a system for regular inspection and maintenance of equipment. The contents of regular inspection include:

(1) Grating: clean the grille slag regularly to avoid the grille blockage and affect the water;

(2) Vacuum pressure of the outlet water pressure gauge: check and record the vacuum pressure gauge regularly, and the vacuum pressure range for normal and stable operation is 0.01-0.04MPa;

(3) The effluent quality and quantity: regularly determine the quality and quantity of the in and out water and make good records;

(4) Activated sludge condition: regularly check the color of activated sludge, conditionally determine the concentration of activated sludge;

(5) Operation status of other parts of the equipment.
