2、 Introduction to main business
The company’s main business is the production and sales of membrane materials and membrane equipment related to urban and rural sewage treatment and urban light environment solutions. The company mainly adopts advanced membrane technology to provide customers with overall technical solutions for the construction of water supply and sewage treatment plants, reclaimed water plants, seawater desalination plants and urban ecosystems, including technical scheme design, engineering design, technical implementation and system integration, operation technical support and operation services, And manufacturing and providing core membrane assembly system and core component membrane materials; At the same time, the company develops, produces and sells household and commercial water purifiers, and provides overall technical solutions for urban light environment, urban ecological environment treatment, municipal and water supply and drainage engineering construction services. 3、 Core technology and R & D investment of the company
(i) Issuer’s core technology
MBR (membrane bio reactor) technology refers to membrane bioreactor wastewater treatment technology. It is a new water treatment process technology that combines membrane separation technology with traditional biological treatment technology. Its main process principle is to replace the secondary sedimentation tank and conventional filtration unit of traditional activated sludge process with ultrafiltration / microfiltration membrane separation technology, so as to realize high-efficiency solid-liquid separation and purification With the interception of biological flora, the treated effluent directly meets the high-quality reclaimed water standard.
1. Process principle
MBR process is an organic combination of membrane separation technology and biotechnology. It is different from activated sludge process. It does not use sedimentation tank for solid-liquid separation, but uses microfiltration membrane separation technology to replace sedimentation tank and conventional filtration unit of traditional activated sludge process, Hydraulic retention time (HRT) and mud age (STR) is completely separated, so it has high-efficiency solid-liquid separation performance. At the same time, the characteristics of membrane are used to prevent the loss of activated sludge with the outflow water, form an ultra-high concentration of activated sludge of 6000-12000mg / L in the biochemical tank, and completely decompose the pollutants. Therefore, the effluent quality is good and stable, the effluent bacteria, suspended solids and turbidity are close to zero, and can intercept biological pollutants such as fecal coliform The treated effluent can be directly reused. The comparison between MBR process and traditional process is as follows:
Innovation principle of MBR technology to traditional technology
As shown in the figure above, the practical application of MBR technology in sewage treatment process, that is, the membrane separation device is directly placed in the biochemical tank to form a new sewage treatment system with the organic combination of membrane separation technology and biological treatment technology. The construction of such a system requires high-performance membrane materials, high-efficiency membrane assembly and advanced MBR process.
Membrane material is the core component to realize membrane separation; Membrane assembler is a device that assembles membrane materials in a basic unit equipment in some form, expands membrane area and improves membrane work efficiency through small volume. It is the key equipment of MBR process; The equipment aggregate composed of several membrane modules and automatic control system is membrane module system; Membrane assembly and its system are the main carrier to realize membrane separation. However, the effect of water treatment depends not only on the performance of membrane materials and the efficiency of membrane assembly and its system, but also on the technical level of MBR process. Therefore, MBR technology includes three key fields: membrane material manufacturing technology, membrane assembly equipment technology and MBR process technology. Membrane technology is recognized as the most advanced sewage treatment technology in the world. It can solve the problems of water pollution and water shortage at the same time.
2. Technical advantages
(1) The effluent quality is excellent and stable, which is superior to the national first-class a standard. The effluent quality reaches class IV of surface water and can be directly reused. Efficient solid-liquid separation separates the suspended substances, colloidal substances and microbial flora lost by biological units in the wastewater from the purified water. It can be directly reused without tertiary treatment, which has high water quality safety.
(2) The process flow is short and the operation control is flexible and stable. Due to the efficient separation of membrane, it is not necessary to set up separate solid-liquid separation tanks such as sedimentation and filtration.
(3) The volume load is high and the floor area is small. The biomass in the treatment unit can be maintained at a high concentration, which greatly improves the volume load. At the same time, the high efficiency of membrane separation greatly shortens the hydraulic retention time of the treatment unit. (4) The biological sludge in the membrane bioreactor can achieve dynamic balance in operation, and the discharge of surplus sludge is only 30% of that of the traditional process.
(5) It has strong adaptability to the change of water quality and strong impact resistance of the system. It prevents the loss of various microbial flora, is conducive to the growth of slow-growing bacteria (nitrifying bacteria, etc.), prolongs the residence time of some macromolecular refractory organics, is conducive to their decomposition, and makes various metabolic processes in the system proceed smoothly. (6) MBR has a high degree of automation and simple management. Due to the use of membrane technology, MBR greatly shortens the process flow and makes the equipment highly integrated and intelligent through advanced computer control technology. So far, MBR is the reclaimed water reuse equipment with the highest degree of automation in China.
(7) The complete separation of residence time (HRT) and sludge age (STR) is conducive to the interception, growth and reproduction of nitrifying bacteria with slow proliferation, with high nitrification efficiency; high sludge concentration and high utilization rate of denitrifying substrate.
(8) Modular design, easy to combine freely according to the water volume. Due to the high integration, MBR forms a standardized and serialized standard equipment, which can be combined and installed by users according to the needs of the project. (9) it can be used as reverse osmosis (RO) pretreatment process. MBR process has a high removal rate of pollutants, and the effluent suspended solids and turbidity are close to zero, which can fully meet the requirements of RO for inlet water quality; taking MBR as the pretreatment technology of RO can not only effectively ensure the continuous operation of RO membrane, control membrane pollution, but also obtain high-quality reclaimed water.
(10) Save land occupation. Due to the high treatment efficiency, high sludge concentration and high efficiency of sludge water separation, MBR process can save land occupation by 30% – 50% compared with traditional process.
