Sewage integrated bacterial fertilizer is a liquid bio-organic fertilizer obtained by treating farm sewage and animal manure through specific technologies. This technique mainly consists of concentrating all animal manure and sewage from the farm into two alternating circular manure tanks, followed by liquid fermentation using a special complex of microorganisms. During the 7-15 days fermentation process, the original manure will be converted into odorless, heavy metal and antibiotic residues are greatly reduced to a negligible safe range, no roots (no seedlings) are burned to plants, and liquid biological fertilizer rich in beneficial microorganisms. At the same time, under the action of rich enzyme preparations, even most of the fecal residue will be decomposed and dissolved.
The advantages of this technology are that the facility cost is low, the operation is simple, and it can solve the environmental protection problems and manure resource problems of the farm at one time, and realize the fertilizer utilization of solid manure and sewage in the farm. In addition, this technology is also in line with the severe environmental pressure faced by the current farms, as well as the national policy of mandatory manure resource utilization.
The application of integrated treatment equipment for rural domestic sewage has brought positive changes to rural life in many aspects:
1. Sanitation environment optimization: Effectively collect and treat all kinds of domestic sewage, eliminate the problems of indiscriminate sewage discharge and peculiar smell, and improve the sanitary environment of the village.
2. Ensure the safety of drinking water: through purification treatment, remove pathogens and harmful substances in sewage, prevent water pollution, and ensure the safety of drinking water.
3. Resource recycling: The treated sewage can be used for farmland irrigation, greening, etc., to realize the reuse of water resources, especially in water-scarce areas.
