The technical core of biochemical treatment is to cultivate microorganisms. The common biochemical treatment of sewage is to cultivate microorganisms in sewage through aeration. Because the number of microorganisms produced by aeration biochemical method can not meet the needs of sewage treatment, three ways are often used in design to make up for the shortcomings of this process: increasing aeration volume, expanding aeration tank and prolonging the long residence time of sewage. However, due to the influence of climate, impact load, water quality and other factors, it is difficult to reach the standard stably, and then the project is upgraded. Some projects have been changed and changed, which is not only costly, time-consuming and laborious.
Microbial generator is a new type of sewage purification equipment developed on the basis of fully drawing lessons from aerobic biological method, immobilized microbial method and biological addition method. Under the conditions of saving sewage treatment investment, reducing sewage treatment land occupation, saving sewage treatment operation cost, eliminating sewage odor and reducing sludge discharge. This equipment can make the sewage superior to the national standard after advanced treatment, and can be discharged or recycled, and it has obtained the national patent of 20 14.
Microbial generator is a waste strengthening equipment in wastewater treatment, which can be used in conjunction with various wastewater or sewage treatment processes. According to the different follow-up processes, it can be organically combined as follows: AB process-microbial generator strengthening 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; Biological aerated filter-microbial generator strengthening process; Biological aerated filter-microbial generator strengthening process and so on.
The generator can be used in 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 and landscape management of rivers, lakes and rivers; Ecological restoration of wetland park; Sewage treatment plant sludge reduction, reclaimed water reuse, high concentration, high ammonia nitrogen, high salt content, heavy metals and other toxic and harmful wastewater treatment fields.
The enhanced treatment process of microbial generator has been applied in Chongqing, Hebei, Guizhou, Jilin and other places in China, involving high-salt wastewater, hospital wastewater, chemical wastewater, slaughter wastewater, food wastewater, pharmaceutical wastewater, printing and dyeing wastewater and other fields. A large number of applications have proved that the CODcr of effluent quality is generally below 20mg/L, and the lowest is 5.95 mg/L; Generally, BOD5 is below 10mg/L, and the lowest is 3.50mg/L.: SS is generally below 20mg/L, and the lowest is 6.55 mg/l.
The microbial generator has the following characteristics:
1, rapidly degrade BOD5, CODcr and TSS, and purify sewage;
2. Improve the removal effect and ability of total nitrogen (TN) and total phosphorus (TP);
3. The treatment efficiency can be increased by about 50%, and the influent load can be increased by about 40%;
4. Respond to the possible emergency failure of aeration tank quickly;
5. Improve the biochemical efficiency of refractory pollutants;
6. There is no need for site reconstruction and expansion, which effectively solves the problem of increased sewage volume or load;
7. Effectively solve the problem of sludge bulking caused by abnormal proliferation of filamentous bacteria;
8. Reduce sludge while treating sewage to achieve the effect of not dredging and removing sludge;
9. It only takes a few days to eliminate the odor in sewage and remove the odor in sewage;
10, using the dominant harmless strains selected in nature or at home and abroad, without the worry of secondary pollution;
1 1. After the pollution is purified, the microorganisms die out due to the loss of life energy and become CO2 and H2O；; ;
12. Uninhibited microorganisms can also be used as bait for fish and plankton; Upgrading the old sewage treatment project, 13, saving investment by 70% compared with other sewage treatment methods;
14, compared with other biochemical treatment methods, it saves about 80% electric energy;
15, and the microbial concentration is as high as 1.8× 1020CFU/ml. The high concentration of microorganisms greatly improves the treatment efficiency, reduces the volume of aeration tank and saves 40% of engineering investment.
16, which solves the technical problem that the number of microorganisms decreases due to climate change and water temperature decrease, thus affecting the sewage treatment effect;
17, the army of microorganisms fought bravely, effectively solving technical problems such as high salt, high concentration, toxicity, harmfulness, chemicals, heavy metals and landfill leachate. Inhibit the growth of microorganisms and make them difficult to survive;
18, to upgrade or expand the old sewage treatment project without changing the civil engineering;
19. Without changing the sewage treatment process, it can effectively remove phosphorus and nitrogen from sewage, improve the effluent quality of treated sewage, and achieve the effect of discharging up to standard or reusing reclaimed water;
20, directly used in the upstream of micro-pollution sources such as rivers and lakes, directly blocking the source of pollution, at the same time effectively controlling micro-pollution, realizing no discharge of sludge, completely innovating the traditional river treatment methods such as dam opening, water cut-off and dredging, and providing ideal equipment for micro-pollution treatment;
2 1, convenient installation, flexible application, simple operation, only one person in charge can complete the task;
22. Flexible layout, small floor space, high degree of automation, simple operation and management, and low operating cost.
