Multifunctional rainwater collection, purification and recycling apparatus for buildings

Abstract

The invention relates to multifunctional rainwater collection, purification and recycling apparatus for buildings. The apparatus comprises a bottom plate, a rotary stirring device positioned on the bottom plate, a frame device arranged on the rotary stirring device, an electric cylinder device positioned above the bottom plate, a purifying device arranged in the frame device, a filtering device positioned above the purifying device, and a piston device arranged on the filtering device. According to the invention, a piston continuously moves up and down, and then the flow rate of rainwater canbe effectively changed, so that impurities are effectively prevented from blocking filter holes, and the smooth purification is ensured; in addition, water periodically flows into the inner part, so that the sewage treatment effect can be improved; and the rainwater can be driven to fully flow when the rainwater is disinfected, so that the sterilization and disinfection effect on the rainwater isensured, the further treatment of the rainwater in a lager period is facilitated, and the rainwater purification effect is ensured.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a multifunctional rainwater collection, purification and reuse device for buildings. Background technique [0002] Due to the shortage of water resources in our country, it is necessary to make full use of water resources, and at the same time need to continuously expand water sources in order to meet people's living and production needs, and more and more attention has been paid to the recycling of rainwater. Because the rainwater on the building contains a lot of impurities and bacteria, it needs to be purified and sterilized before the rainwater on the building can be fully utilized. The existing rainwater purification and sterilization are often carried out separately, and the rainwater purification device cannot realize The sufficient purification treatment of rainwater has poor purification effect and cannot effectively remove impurities in rainwater, and the range ...

Problems solved by technology

Because the rainwater on the building contains a lot of impurities and bacteria, it needs to be purified and sterilized before the rainwater on the building can be fully utilized. The existing rainwater purification and sterilization are often carried out separately, and the rainwater purification device cannot realize The sufficient purification treatment of rainwater has a poor purification effect and cannot effectively remove impurities in the rainwater, and the flow rate of the water changes in a small range during the purification process, making it easy for impurities in the rainwater to block the filter holes and affect the purification treatment of rainwater , and even shorten the service life of the purification device; at the same time, when the disinfection device disinfects rainwater, the rainwater is often fixed, and the impurities in the rainwater are easy to precipitate out at this time, which will affect the irradiation range of ultraviolet rays and affect the sterilization of rainwater.
