Brand: Haotian film Model: HT-mbr001 film - bioreactor (MBR) introduced the film - bioreactor (Membrane-Bioreactor, MBR) technology is the modern membrane separation technology and traditional biological wastewater treatment technology combine to form after a sewage treatment The new technology, called "membrane separation activated sludge process." Membrane - bioreactor MBR technology can greatly improve the effectiveness of biological treatment, processing efficiency will be higher, the water quality will be better. On the one hand, the film - bioreactor membrane separation technology with efficient activated sludge biochemical reactions in the pool and organic molecules and other trapped live, continue to stay in the pool biochemical biochemistry, increase the flexibility of activated sludge biochemical reactions in the pool concentration, which can easily degradable substances for continuous reaction, degradation, so that the degradation of wastewater biochemical reactions proceed more quickly and thoroughly, better water quality. On the other hand, since the film - bioreactor membrane separation module high filtration accuracy, and ensure the water is clear and transparent, thereby eliminating the need for secondary settling tank, greatly improving the solid-liquid separation capability of the system. 2.2 Membrane - bioreactor (MBR) is characterized by (1) a high pollutant removal efficiency, good water quality can be directly reused. Membrane - bioreactor allows greater air circulation flow of sewage can be completely mixed, the active sludge is highly fragmented, greatly improving the specific surface area of ??the activated sludge, and the substrate affinity and ability to improve the removal of contaminants An important reason for the rate, which is the larger floc formation of conventional activated sludge process can not match. Plus high precision filtration membrane separation module, resorted to water is clear and transparent, can meet the reuse water standards, can be directly reused. (2) hydraulic retention time (HRT) and sludge retention time (SRT) is completely separated from the membrane - bioreactor using membrane separation module to the activated sludge tank biochemical reactions completely entrapped in the biochemical reaction cell, in order to achieve the HRT SRT and completely separated, so that operation of the system more flexible and stable control. (3) biological concentration high volume load, covering the province as a result of the film - the use of membrane bioreactor sludge components of biochemical reactions in the pool completely trapped in the biochemical reaction tank, sludge concentration can reach 8-12g / l about biological and biochemical reaction cell concentration can reach 2-3 times that of conventional activated sludge process, so the volume load, covering the province. (4) long sludge age, less residual sludge. Due to the long sludge age, microbial and biochemical reactions within the pool of multi-source decay period, the bioreactor also played the role of "sludge nitrification tank", thus significantly reducing the excess sludge production, saving the remaining sludge treatment costs. Good (5) nitrogen removal. Because of the film - the use of membrane bioreactor sludge components of biochemical reactions in the pool completely trapped in the biochemical reaction cell, help slow the proliferation of nitrifying bacteria retention, growth and reproduction, greatly improving the nitrogen removal system. (6) Anti-shock load capability due to the film - the use of membrane bioreactor sludge components of biochemical reactions in the pool completely trapped in a pool of biochemical reactions, changes in the system during operation of activated sludge concentration of organic matter due to enter changes, and achieve a dynamic equilibrium, greatly improved resistance to shock loading capacity of the system, water quality and stability. (7) The system is easy to achieve automatic control, easy operation and management. 2.3 Membrane - bioreactor (MBR) of the main application areas ● biodegradable industrial waste: chemical waste, medical waste, wastewater, landfill leachate ● high concentration organic wastewater: food processing wastewater, aquaculture wastewater ● General wastewater: domestic wastewater, ● micro urban sewage pollution of drinking water station: water, water reservoir ● upgrading sewage treatment facilities in the third chapter of polypropylene (PP) hollow fiber membrane module curtain 3.1 polypropylene (PP) hollow fiber membrane module Introduction polypropylene curtain (PP) of the hollow fiber membrane module of the curtain (MBR membrane) is a membrane - bioreactor membrane separation module, also the membrane - the core of the bioreactor, from polypropylene (PP) of the hollow fiber membrane, and the outlet pipe connection alive contact other components. Common MBR membrane in the following figure. Film can be 810mm long and 1050mm two types of membrane area can be installed 8m2, 12m2, 16m2 and so on. The most common size chart MBR membrane: prefix = o 3.1.1 polypropylene hollow fiber membrane (PP) is characterized by (1) the high strength of the film due to polypropylene (PP) hollow fiber membranes prepared using the "melt extrusion, stretching molding "film forming method, a polypropylene (PP) random orientation of macromolecules and thus high strength of the film, in the high strength aeration and periodic chemical cleaning process, the film is not easily broken. (2) chemically stable membrane performance good polypropylene (PP) of the hollow fiber membrane production process, not adding any additives and pore-forming agent, and thus good chemical stability. Strong acid or alkali can be used to clean, you can use chlorine disinfectant to clean a lot of microbial contamination of the membrane surface, and after cleaning the flux is good. 3.1.2 polypropylene (PP) The main technical parameters of the hollow fiber membrane hollow fiber membrane ● Material: Polypropylene (PP) ● the inside diameter of the hollow fiber membrane: 0.25-0.30 mm ● hollow fiber membrane outer diameter: 0.35-0.40 mm ● interception aperture : 0.1 ~ 0.2μm ● permeability:> 7.0 × 10-2 (cm3 / cm2 · s · cmHg) ● longitudinal strength: 120 MPa ● Porosity: 40-50% 3.2 polypropylene (PP) of the hollow fiber membrane module curtain 3.3 Models of polypropylene (PP) of the hollow fiber membrane module of the technical requirements 3.3.1 polypropylene (PP) of the hollow fiber membrane module of the curtain performance parameters (see Table I) 3.3.2 polypropylene (PP) hollow fiber membrane curtain Appearance component requirements: polypropylene (PP) hollow fiber membrane module curtain clean appearance, no broken wires. 3.3.3 polypropylene (PP) sealing requirements of the hollow fiber membrane module curtain: Polypropylene (PP) hollow fiber membrane module curtain overall pressure test at 0.10MPa pressure without leakage, the collector pipe glued at the firm, sealed reliable.
