There are many farmhouses in my hometown, usually located at the foot of the mountains. They require 5 tons of water per day, and the water quality should meet the second-grade standards set by Tianjin. What kind of treatment is suitable for this? Due to its location at the foot of the mountain, piping is difficult to handle, and it is not possible to implement unified piping solutions ； If integrated equipment is used, then low operating costs and simple operation and maintenance requirements are necessary. So, what’s the best way to handle this?
I’m not sure whether installing a small aerator in a septic tank or an integrated system can achieve surface water quality equivalent to Class II standards.
The wastewater from rural households is mainly kitchen waste water. . . As for feces, farmers use it as organic fertilizer. . .
Are there any data? Can we collect data for a few days for monitoring?
Biological aeration treatment is still needed! Most cost-effective!
There isn’t any. . . A friend brought this up. . . I checked some relevant information and found that there is no reasonable solution. . .
However, running this debugging requires human effort. . . It’s impossible for the village to find anyone to manage it. . .
We have manufactured similar equipment before, namely biochemical tanks, which require 3 pumps with a power of 0.55KW each. To achieve the second-level standards in Tianjin, the equipment must be equipped with aerobic sedimentation and filtration systems (including 3 water pumps: one for jet aeration, one for filter backwashing, and one for sludge discharge and recirculation). It is estimated that the cost of the equipment at the factory level is also around 40,000 yuan (including a week of debugging by engineers).
Is operation and maintenance simple? It mainly involves the monitoring of water quality parameters. . . The village does not have the necessary testing facilities. . .
There’s nothing that can be done about it. It’s possible to meet the standards; it’s just more difficult to manage filtration. Is it necessary to reach Level B? Make it looser. The Environmental Protection Agency needs to take into account the actual circumstances
Mm-hmm. . . This can cover the entire topic. . . After all, in rural areas in the past, people produced and sold what they grew, so pollution was minimal. . . However, with rural urbanization, self-production and self-sales can no longer meet the demands. . .
