Embodiment 1
[0054] Embodiment 1 laboratory urban domestic sewage treatment test
[0055] The urban domestic sewage used in the test treatment comes from the sewage pipe network of Zhengzhou City, and 0.12kg / m of new microbial flora combination agent is put into the sewage 3 After 15 days, a biofilm will be formed, and the water quality will be clarified. During the protection period, continue to add the microbial flora combination agent at 0.02kg / m 3 . The water quality test results before and after the test treatment are shown in Attached Table 1.
[0056] The production steps of the above-mentioned novel microbial flora composition are as follows:
[0057] (1) By weight percentage, the weight ratio of plant powder (fragrant wood powder, rotten wood powder, peanut shell powder, black sesame shell powder, black bean shell powder, and castor plant shell powder is 1:2:2:4:3:2 ) 70%, minerals (keel powder, weathered stone powder, weathered brick powder, rust powder weight ratio is 2:3:3:5...
Embodiment 2
[0060] Embodiment 2 mixed industrial wastewater treatment test
[0061] Take the mixed industrial wastewater discharged from many factories in the suburbs of Zhengzhou City, and put the new microbial flora composition 0.09kg / m into the wastewater 3 After 20 days, a biofilm was formed, and the water quality was clarified. See attached table 2 for the water quality test results before and after treatment.
[0062] The production steps of the above-mentioned novel microbial flora composition are as follows:
[0063] (1) By weight percentage, the weight ratio of plant powder (fragrant wood powder, rotten wood powder, peanut shell powder, black sesame shell powder, black bean shell powder, and castor plant shell powder is 2: 2: 1: 4: 3: 2 ) 80%, minerals (keel powder, weathered stone powder, weathered brick powder, rust powder weight ratio is 2:3:3:5) 3%, animal meal (shrimp shell powder, crab shell powder, oyster shell powder, human The weight ratio of baking powder and white gl...
Embodiment 3
[0066] Example 3 Xinmi City Xinxin Paper Co., Ltd. Recycled Paper Sewage Treatment Project
[0067] The company produces more than 17,000 tons of container board annually, and the daily wastewater discharge is 1,000-1,500 tons. The COD content of wastewater discharged during the production process is 1,800-2,100 mg / L, BOD 5The average value is as high as 568mg / L. In February 2006, the present invention combined with artificial wetlands was used to carry out advanced treatment of papermaking wastewater. The treatment process is: put bacterial agents in the original wastewater for pretreatment, and then pass through the grid into the coagulation sedimentation tank for precipitation. , and then enter the aeration tank for oxygenation and oxidation, and then add high-efficiency complex microbial flora combination agent for treatment, and finally the supernatant is introduced into the constructed wetland for treatment. It took 40 days from the test water inflow to the effluent reac...
