The invention discloses an environment-friendly and energy-saving courtyard type rain water collecting, treating and recycling
system, and specifically relates to the environment-friendly and energy-saving courtyard type rain water collecting, treating and recycling
system which is suitable for an
arid area and a semi-
arid area. The environment-friendly and energy-saving courtyard type rain water collecting, treating and recycling
system is characterized by comprising a rain water collecting
pool, a flow distributing well, a flow releasing
pool, a
constructed wetland, a rain water storing
pool, a sand filtering pool and a
clean water pool, wherein the upper-layer rain water collecting pool, the flow distributing well, the
constructed wetland and the sand filtering pool are connected in sequence, the lower-layer flow releasing pool, the rain water storing pool and the
clean water pool are connected in sequence, the flow releasing pool is located under the rain water collecting pool, the rain water storing pool is located under the flow distributing well and the
constructed wetland, and the
clean water pool is located under the sand filtering pool. According to the environment-friendly and energy-saving courtyard type rain water collecting, treating and recycling system disclosed by the invention, the occupied area is small, the
energy consumption is low, the
operating cost is low, and the maintenance is simple; the functions of beautifying a courtyard and purifying air are obtained as green ecological plants are planted on the constructed
wetland; the courtyard waterlogging can be reduced, environmental
pollution caused by initial rain water can be reduced, the living standard of a farmer can be increased, and meanwhile, the rural
ecological environment can also be effectively improved.
