However, solar radiation is intermittent and discontinuous, that is, it is weak in the morning and evening and strong at noon. Therefore, the light and heat gathered by the solar concentrating glass plate vary greatly in a day, and it is restricted by weather and other factors, which has a great impact on the purification efficiency.

Embodiment 1
[0018] See attached figure 1 , the present invention includes: rainwater abandonment flow, rainwater pretreatment and rainwater storage three parts. Mud and sand area 2, sand settling area 3, inclined plate (pipe) sedimentation area 4, clear water area 5, waterwheel 7, baffle plate 10 and outlet pipe 14 constitute a rainwater disposal and storage device with pretreatment. The water inlet pipe 1 and the faucet 13 are installed at the junction of the mud-sand area 2 and the grit-sand area 3 . The water outlet pipe 14 is located at 0.2m below the liquid level of the clean water zone 5 . The total height of the whole device is 1.5m, the height of the clear water area 5 is 0.5m, and the diameter is 0.5m; the height of the inclined plate area 4 is 0.5m, and the diameter is 0.5m; The diameter is 0.5m, the diameter of the lower bottom is 0.2m; the height of the mud and sand area 2 is 0.2m, the diameter is 0.2m, the diameter of the opening in the middle of the bottom is 0.1m, the ope...

The invention discloses an automatic rainwater removal and storage device with a pretreatment, and belongs to the field of water supply and sewerage works and environmental project. The bottom part of a device is a muddy sand zone and a sand setting zone, the middle part is a sloping panel (pipe) settling zone, and the upper part is a clean water zone. The side face of the sand setting zone is provided with a baffle and the bottom part is bored. After entering the device, the initial rainwater flows downwards and drains through the hole at the bottom part. The drained rainwater gravity flows to a water bucket of a watercart, and pushes the watercart to rotate; and thereby, the baffle is driven to rotate. After the removal for a period of time, the baffle can close the bottom hole of the device, so that the removal process is finished. Subsequently, rainwater entering the device is flowed upwards, and submerged after passing through the muddy sand zone and the sloping panel (pipe) settling zone, and the pretreatment process is completed. The automatic rainwater removal and storage device ingeniously uses hydraulic power to realize the removal of the initial rainwater and adjusts the removal amount by adjusting the watercart. After finishing the removal, the device is changed to be a water storage tank to store rainwater. The device is realized by using gravity and needs not the additional power.
Description
technical field [0001] The invention relates to a device for automatically discarding and storing rainwater with pretreatment. The device is used to discard, pretreat and store rainwater to realize resource utilization of rainwater. The invention belongs to the fields of water supply and drainage engineering and environmental engineering. Background technique [0002] With the development of our country's economy, the water pollution situation is getting worse day by day. At the same time, people's requirements for drinking water are getting higher and higher, and the source water that meets the standard is getting less and less. During the rainfall process, due to the leaching effect of the rainfall on the atmosphere and the scouring effect of the surface runoff on the sediments on the underlying surface and the decomposed educts of the surface building materials, the initial rainwater pollution is relatively high. With the continuation of the rainfall, the pollutant cont...
