Biochemical system startup recovery:
In the face of complex wastewater, Guangzhou vibration clear companies usually choose the way to synchronize the cultivation of the system to start the system. The growth of microbial populations experience to lag phase, exponential growth phase, stable growth phase and decline phase, the seeding quantity in appropriate, suitable nutrition and environmental conditions, bacterial adaptation period is short. Therefore, initiation of environmental and nutritional substrates of bacteria reproduction very important. Wastewater with high BOD/COD ratio and low toxic substances can be directly into the raw water, such as slaughter, food, municipal wastewater, etc., for biochemical and toxic substances, such as coking, pharmaceutical, leather and other waste water, it should be pretreated by a certain proportion of waste water (can be added water), and maintain a low concentration of COD (generally not more than 500mg/L), and add a moderate amount of exogenous carbon source.
The quick start of the biochemical system is: activation of the low concentration of culture, the increase of the load, and the enhancement of the full load operation.
First of all, should be prepared to do all the basic work, such as the normal operation of the equipment, data analysis, testing equipment, waste water treatment to meet the design requirements.
Activation: activation of the dormant state of the organism (see Annex).
Seeding: the activated microbial species are evenly cast into the biological contact oxidation pond.
Culture: to enhance the daily part of the wastewater to the biochemical pool. The initial load should be treated with the type of waste water and the waste water with good biodegradability and low toxic substances is designed to be 30%-50% influent, or the 10%-30% should be taken for the low load. During a day to supplement the 1 species. When the water quality is good, it is indicated that the microorganism has adapted to the current load, and can fully degrade the substrate, which can increase the load, and gradually increase to full load operation. After the full load operation, if no accident occurs, stop the cast and the strain.
Vibration formula can complete the cultivation and domestication of aerobic stage in 2 to 3 weeks.
Should pay attention to is that regardless of the incubation period and enhance the load period, should pay close attention to the runoff water quality, water quality regulation to strain the optimum range of parameters before entering the system, the following is Zhenqing strains the optimum range:
PH value: 6.5 ~ 7.5.
Temperature: 25 ~ 30.
Dissolved oxygen: oxygen tank at least 2 mg / L.
The trace elements: Flora proprietary in its growth will require many elements, such as potassium, calcium, magnesium, iron etc..
Note: when the contaminated area contains a fungicide, they should study their effect on the microbial species.
