The invention discloses a novel multifunctional
sewage treatment system, comprising a drawer-type sealed box body in which multiple types of
filtration substrates are laid, wherein multiple drawer
layers with placing cavities are arranged in the box body, a
filtration substrate for purifying
sewage is placed in the drawer
layers respectively, and large pieces of blue stones,
pebble gravels, fine sand,
modified zeolite, a nano
composite material and a soil layer are placed in the multiple drawer
layers from bottom to top. The novel multifunctional
sewage treatment system disclosed by the invention strengthens the
nitrogen and
phosphorus removal efficiency of a
sewage treatment process, and solves the problem that heavy
metal pollution is difficult to eliminate by a traditional
sewage treatment process, and meanwhile, the
workload of later-stage maintenance of the
sewage treatment system is reduced.
