Kirjeldus
Why is COD removal efficiency unstable in high-organic-load wastewater treatment?
Pulp and paper mill wastewater typically contains large amounts of residual fibers, cellulose, and soluble organic matter. When the organic load exceeds the treatment capacity of conventional biological systems, it results in reduced COD removal efficiency and unstable system operation.
Solution: The DC 85 provides abundant attachment surfaces for microorganisms, increases the effective biomass in the reaction tank, promotes the growth of heterotrophic bacteria, accelerates the degradation of organic matter, and improves the removal efficiency of COD and BOD in secondary treatment systems.
DC 85 tselluloosi- ja paberitööstuse reovee sekundaarseks töötlemiseks
85 auguga vertikaalse triibuga eenduv MBBR-materjal on ülitõhus biokile kandja, mis on loodud maksimaalseks protsessi intensiivistamiseks täiustatud reoveepuhastussüsteemides. Selle tipptasemel disain integreerib 85 täppisprojekteeritud aksiaalset läbivat auku spiraalsete vertikaalsete triipude eenduvatega, luues mitme võrega arhitektuuri, mis maksimeerib kaitstud biokile kasvupinna (>1200 m²/m³), säilitades samal ajal erakordse hüdraulilise jõudluse. Nanokomposiidist HDPE-st, mis on tugevdatud süsiniknanotorudega, valmistatud materjal pakub enneolematut mehaanilist vastupidavust ja biokile säilimist äärmuslike orgaaniliste koormuste korral (kuni 20 kg COD/m³·päevas). Astmeline triipude konfiguratsioon tekitab kontrollitud mikroturbulentsi, suurendades hapnikuülekande efektiivsust 45–50% võrreldes tavapäraste materjalidega, kaitstes samal ajal biomassi nihkejõudude eest kiiretel reaktoritel. Optimeeritud toitainete eemaldamiseks, toksiliste saasteainete lagundamiseks ja ruumipiirangutega bioreaktori rakenduste jaoks.
Why do traditional activated sludge systems suffer from insufficient biomass and limited treatment capacity?
The traditional activated sludge process has limited capacity to retain microorganisms, resulting in insufficient active biomass within the system and requiring larger reaction tank volumes to meet treatment requirements.
Solution: The DC 85 provides a stable biofilm attachment medium, enhancing microbial retention capacity and system biomass, thereby increasing wastewater treatment capacity without the need for large-scale civil engineering modifications.
Why is DC 85 MBBR MEDIA the latest choice for industrial and domestic wastewater treatment?
1. High Specific Surface Area for Biomass Growth
The specific surface area of DC 85 is >1200 m²/m³.DC 85 provides ample attachment space for microorganisms, increases the effective biomass in the reaction tank, and improves the overall treatment efficiency of secondary biological treatment systems for wastewater in the pulp and paper industry.
2. Optimized Multi-Hole Structure for Stable Biofilm Formation
The DC 85 features an optimized porous structure design that combines internal protective channels with an external attachment surface, promoting stable biofilm formation and reducing biofilm loss caused by water flow erosion during long-term operation.
3. Enhanced Mass Transfer Performance
The open structure allows for thorough contact between paper mill wastewater, dissolved oxygen, and microorganisms, thereby improving oxygen transfer efficiency and pollutant diffusion, promoting microbial activity, and effectively enhancing pollutant degradation.
4. Efficient Removal of COD and Organic Pollutants
Pulp and paper mill wastewater typically contains high concentrations of organic matter, including residual fibers, cellulose, and soluble organic pollutants. DC 85 provides a favorable attachment surface for heterotrophic bacteria, promoting the removal of pollutants such as COD and BOD, and helping the system maintain stable biochemical treatment performance.
5. Suurepärane fluidisatsiooni jõudlus
DC 85 has a density close to that of water; under aeration and water flow, it maintains a good state of suspended fluidization, ensuring continuous and thorough contact between the packing material, wastewater, and dissolved oxygen, while reducing issues such as sedimentation and uneven biomass distribution.
6. Valmistatud 100% valgest neitsi HDPE-st
The DC 85 is manufactured from 100% virgin white HDPE material and offers excellent chemical stability, corrosion resistance, and weather resistance, making it suitable for long-term, continuous operation in pulp and paper wastewater treatment systems.
7. Pikk tööiga
The DC 85 has a service life of over 15 years, effectively reducing the frequency of media replacement and lowering the long-term operating and maintenance costs of paper mill wastewater treatment systems.
8. Paindlik täitesuhe
The DC 85 allows for flexible adjustment of the packing density based on the characteristics of the paper mill wastewater, the volume of the reaction tank, and treatment requirements, thereby meeting the design needs of various wastewater treatment processes.
9. Ideal for MBBR and IFAS Secondary Treatment Systems
DC 85 can be applied to new MBBR systems or to upgrade conventional activated sludge processes to the IFAS process, increasing system biomass, enhancing COD removal capacity, and improving overall treatment performance without the need for major civil engineering modifications.
