The difference between treating sewage with Nongshengle stock solution and not adding microorganisms now is that we can choose what kind of microorganisms to use to treat sewage.
In general sewage treatment, sewage contains microorganisms to treat sewage, so it will emit serious odor during microbial fermentation. Especially when the temperature is high, despite the high efficiency of microbial treatment. However, the odor produced is relatively heavy, because the bacteria contained in the sewage are mostly spoilage bacteria.
In addition, due to high oxygen consumption fermentation, the aeration tank must be inflated for a long time, which requires a lot of electricity.
When using Nongshengle stock solution to treat sewage, Nongshengle stock solution can inhibit the growth of spoilage bacteria. Effectively decompose organic matter in sewage through fermentation. Therefore, the sewage treated with Nongshengle stock solution will not give off bad smell. Because the raw solution of Nongshengle can be fermented anaerobically, it does not need long-term aeration, which can reduce the power cost. In addition, the use of Nongshengle stock solution in sedimentation tank can slow down the accumulation of activated sludge. Compared with the general traditional methods, it can effectively reduce the values of BOD (biological oxygen consumption), COD (chemical oxygen consumption) and SS (suspended solids in water) in sewage. The use of Nongshengle stock solution does not need to add other hardware equipment, as long as it is put on time and in quantity, its effect can be achieved.
Sewage treatment method use nongshengle stock solution
1. Add the raw solution of Nongshengle into the sedimentation tank and aeration tank;
The dosage is one thousandth of the treatment capacity every Sunday, which means that the raw liquid of Nongshengle can treat 1 000 liter of sewage every week.
2. Hang the fermented materials in the mesh bag of the sedimentation tank (self-made);
The dosage is about 1 ton, one kilogram can be used, and new fermentation materials are changed once every three months.
