The invention discloses a building
sewage treatment and pipeline planting
system. The
energy consumption of a
large city accounts for 75 percent of the
global energy consumption, and the
greenhouse gas emission amount accounts for 80 percent of the global emission total amount; in China, the gross area is larger than 4 billion square meters, and 2 billion cubic meters are newly built each year..., so that the transformation development of
building energy-saving and low-carbon cities is urgent, and the three-dimensional afforesting of an
urban space is valued more and more. The building
sewage treatment and pipeline planting
system consists of a
sewage methanedization energy utilization
system, a sewage
resource utilization system and a pipeline planting system; domestic sewage is flushed into a
fermentation tank [2] through a sewage discharging
pipe [1], and
methane gas is collected and used;
biogas slurry is discharged into a planting
pipe [3] in the planting system through a
water collection tank [9] and a
biogas slurry communicating
pipe [10], so that sewage can be collected and used. By the simple and convenient building afforesting and energy-saving ecological system, an urban roof is changed into a vegetable garden, and conversion of sewage into
methane gas
new energy and sewage resources is one of the most economic
building energy-saving and emission-reduction projects. The building
sewage treatment and pipeline planting system has the best advantages of water and
energy conservation, economy and environment friendliness.
