For the wastewater drying bed, the drying amount is small, and the dried wastewater filtrate has high salt content, high density and high solid content. Therefore, for the two water distribution systems, the problem of deposition is caused by adopting small-pipe-diameter blockage or adopting large-pipe-diameter low-flow rate.
