The invention provides an energy-saving rainwater harvesting device capable of quantitative observing,
belonging to the technical field of water treatment. The device is suitable for washing cars in the parking
lots. The device mainly comprises an initial rainwater discarding device, a physical sedimentation tank
and a rainwater harvesting bucket, wherein the initial rainwater discarding device comprises a buffer
slot, a COD (chemical oxygen demand) sensor, a CPU, a steering engine and a butterfly valve; the initial
rainwater discarding quantity is controlled by a COD concentration detection method; the physical
sedimentation tank comprises a buffer plate, a detachable reverse seepage slot, inclined plates, concave
slots, drain outlets and the like; the mid-late rainwater is treated by adopting the principle of reverse
seepage; and the rainwater harvesting bucket mainly comprises an overflow vent, a water quantity
observation instrument, a water receiving hole, a drain outlet, a water pump, an antifreezing film, a solar
absorption film and the like. The device has the following beneficial effects: the device can accurately
discard, purify and recycle the rainwater according to different degrees of pollution of the rainwater, can
quantitatively observe the water quantity and is accurate, flexible, energy-saving and
environment-friendly; and the device simultaneously solves the problem of recycle of the rainwater in
the districts, architectural complex and regions and can cut down on the pollution load of the urban
rainwater and improve the utilization ratio of the rainwater resources
