| Curtain bio-carrier The DWP curtain type biological filler uses special textile technology to make three-dimensional three-dimensional microbiological fixed filler through rice king environmental protection. China Patent Number: ZL 2017 2 0976702.2 Due to its huge specific surface area, it can retain high-density bacteria, greatly increase microbial concentration, improve treatment efficiency, and resist impact load, which can significantly reduce the capacity of biological reaction pools. The special structure of fluffy divergence allows the colonies of different species to obtain a suitable growth environment. Anaerobic, aerobic, and aerobic bacteria exist on the curtain biological fillers at the same time. Synchronous nitrification and denitrification can be achieved without internal and external sludge reflux. effect, Good effect of denitrification. The good hydrophilicity of special materials makes biological hanging membranes rapid and biological adhesion strong. It is easy to achieve the separation of water retention time and sludge retention time. The sludge is longer, and microorganisms with long generation cycles are more likely to form dominant colonies. For reducing biological sludge, There are obvious advantages in improving the removal efficiency of refractory organic compounds. Special weaving process, can be tailored to the needs of users, no need for steel support, convenient on-site installation, greatly reduce the consumption of installation materials and manpower, reduce investment. Excellent polymer material, greatly enhance the strength of the filler, corrosion resistance, anti-aging ability, after hanging film filler life of at least 10 years. |

| Bio-rope carrier, Bionic water grass 1. Modified carrier biological effects On the basis of braided braided braiding, the Biofilm filler performs appropriate hydrophilic and bioaffinity and electrical modification of the synthetic fiber pair, as well as the addition of substances that promote the metabolic activity of microorganisms, and improves the membrane speed, film content, and stability of the Biofilm. Wait. Under the premise of activated sludge input, only 2 H is required at the earliest, and the system is put into operating time less than one month. 2. Loop rope structure The rope type biological filler adopts elastic PE material as the skeleton, and the mixture is mixed with a fluffy PP material. The alignment adopts a snake braided braided pattern to form numerous circular fibers to form a radial structure and increase its surface area. At the same time, breathable and permeable water, Suitable for the growth and reproduction of various microorganisms, so that the concentration of attached microorganisms can reach 15,000 mg/L or more; The perimeter ring radiation structure formed by elastic materials and soft materials increases the porosity of the fillers, so that the solid, liquid, and gas phases are well transmitted; The unique ring structure can effectively avoid the excessive peeling of the Biofilm due to the impact of water flow. 3. The strongest wire The biological rope filler adopts a high-strength polypropylene mixing process, and the single mixing line can withstand 15kg of tension. Due to the unique central rope fixation method of the rope type biological filler, there are a total of 12 mixed lines in the single section, and the measured biological rope filler can withstand 80kg. Tension. |

| Fill suspension rope Special biological curtain suspension rope, high tensile strength. There is a non-slip keel on the outside. Biological rope special suspension rope, 50 mm interval with suspension hook, high tensile strength, aging resistance. |
 |
| Fiber filter material (for upflow high-speed filtration) PP fiber is subject to special waterproof treatment, making its density lower than water and floating above the water surface; The processing adopts hot-drawn hot air technology, which makes it have good strength, high porosity, long service life and high pollution tolerance. It is an ideal filter material for high-speed fiber filter. |
