There are many people in my country studying the field of biological sludge treatment who are very good at it. Recently we have discovered a new and very good equipment "Microbial Generator".
Biochemistry is the mainstream of sewage treatment in China. In the past, it was mainly based on the development of biochemical processes. The core technology of biochemical treatment is to cultivate microorganisms. The commonly used biochemical treatment of sewage is to use aeration in sewage. Because the amount of microorganisms produced by the aeration biochemical method cannot meet the needs of sewage treatment, three methods are often adopted during design: increasing the aeration volume, expanding the aeration tank, and increasing the long residence time of sewage to make up for the technological shortcomings. insufficient. However, due to the influence of climate environment, impact load, water quality factors and other factors, it is difficult for the effluent water quality to reach the standard stably, which leads to engineering upgrades and engineering transformations. Some projects are changed again and again, upgraded and upgraded, which is not only costly, time-consuming and labor-intensive.
The microbial generator is a new sewage purification equipment developed by fully drawing on the design techniques of the aerobic biological method, the immobilization method of embedded microorganisms, and the biological agent addition method. This equipment can save sewage treatment investment, reduce sewage treatment land occupation, save sewage treatment operation costs, eliminate sewage odor, reduce sludge discharge, etc., so that the sewage after intensive treatment is better than the national standard and can be discharged or recycled. Obtained national patent in 2014.
Microbial generator is waste intensification equipment in wastewater treatment. It can be used with various wastewater or sewage treatment processes. Depending on the subsequent process, it can be organically combined into: AB method-microbial generator intensification process; A/O method - microbial generator strengthening process; A2/O method - microbial generator strengthening process; oxidation ditch - microbial generator strengthening process; SBR - microbial generator strengthening process; contact oxygen method - microbial generator strengthening process, membrane Bioreactor-microbial generator strengthening process; Aerated biological filter-microbial generator strengthening process; Aerated biological filter-microbial generator strengthening process, etc.
The generator can be used for new sewage treatment projects; it can also be used for upgrading old sewage treatment projects; it can also be used for nitrogen and phosphorus removal, rivers, lakes, and river landscape management; and ecological restoration of wetland parks. ; Sewage treatment plant sludge reduction, reclaimed water reuse, high concentration, high ammonia nitrogen, high salt content, heavy metal and other toxic and harmful wastewater treatment fields.
The use of microbial generators for enhanced treatment processes has already been used in projects in Chongqing, Hebei, Guizhou, Jilin and other places in my country. The cases involve high-salt wastewater, hospital sewage, chemical wastewater, slaughtering wastewater, and food wastewater. , pharmaceutical wastewater, printing and dyeing wastewater and other fields. A large number of applications have proved that: the effluent water quality CODcr is generally below 20mg/L, with a minimum of 5.95mg/L; BOD5 is generally below 10mg/L, with a minimum of 3.50mg/L; SS is generally below 20mg/L, with a minimum of 6.55mg/L.
The microbial generator has the following characteristics:
1. Rapidly degrade BOD5, CODcr, and TSS to purify sewage;
2. Increase total nitrogen (TN ) and total phosphorus (TP) removal effect and removal capacity;
3. The treatment efficiency can be increased by about 50%, and the water inlet load can be increased by about 40%;
4. Quickly respond to possible emergency failures in the aeration tank;
5. Improve the biochemical efficiency of difficult-to-decompose pollutants;
6. Effectively solve the problem of increased sewage volume or load. There is no problem of site reconstruction and expansion;
7. Effectively solve the problem of sludge expansion caused by abnormal proliferation of filamentous bacteria;
8. Reduce the amount of sludge while treating sewage to achieve The effect of removing mud without dredging;
9. It only takes a few days to digest the taste in sewage and remove the odor in sewage;
10. Use natural or domestic and foreign materials The advantageous harmless strains cultivated are free of worries about secondary pollution;
11. After the pollution is purified, the microorganisms lose their energy for survival and self-destruct, turning into CO2 and H2O;
12. Unkilled microorganisms can also become food for fish and plankton; Upgrade old sewage treatment projects, 13. Save investment by 70% compared with other sewage treatment methods;
14. Compared with other sewage treatment methods Biochemical treatment method saves about 80% of electricity energy;
15. The concentration of microorganisms is as high as 1.8×1020CFU/ml. The high concentration of microorganisms greatly improves the treatment efficiency, reduces the volume of the aeration tank, and saves 40% of project investment. ;
16. It has solved the technical problem of reducing the number of microorganisms due to climate change and lowering water temperature, which in turn affects the effect of sewage treatment;
17. The army of microorganisms works together and fights effectively. It has solved the technical problems of high salt, high concentration, toxic, harmful, chemical, heavy metal, garbage permeate, etc. that inhibit the growth of microorganisms and make it difficult for microorganisms to survive;
18. Realize old sewage without changing the civil construction. Upgrading or project expansion of treatment projects;
19. Without changing the sewage treatment process, effectively remove phosphorus and nitrogen in sewage, improve the quality of treated sewage effluent, and achieve discharge standards. Or the effect of reclaimed water reuse;
20. It is directly used in the upstream of rivers, lakes and other micro-pollution sources to directly block the source of pollution. While effectively controlling micro-pollution, it achieves no mud discharge, which completely revolutionizes the Traditional river management is inseparable from dams, water cuts, and dredging methods, which provide ideal equipment for micro-pollution control;
21. It is easy to install, flexible in application, and simple to operate. Only one person can manage it. Able to complete tasks;
22. Flexible layout, small footprint, high degree of automation, simple operation and management, and low operating costs.
