The invention relates to a rainwater treatment and recycling integrated device, wherein rainwater firstly passes through a coarse strainer 7 to remove impurities such as leaves, scraps, broken stones, packaging bags and the like; then removing impurities with small particle size such as gravel and the like through a fine filter screen 9; then removing impurities such as floaters and flocculates with large particle size through the coarse filtering layer 10; finally enters the fine filter layer 17 for deep treatment.
The fine filtering layer 17 is a mixture of several filtering materials, and comprises the following components in percentage by mass: 15-25 wt% of anthracite filter material, 20-30 wt% of quartz sand, 15-20 wt% of steel slag filter material, 20-30 wt% of activated carbon filter material, 15-20 wt% of manganese sand filter material and 10-15 wt% of charcoal particles. Wherein, the components have interaction with each other: the combination of the anthracite filter material and the charcoal particles can play a good role in adsorption and filtration, the steel slag filter material has chemical precipitation and adsorption effects, and can adsorb and remove heavy metal pollutants such as phosphorus, chromium, zinc and the like in rainwater, iron rust generated by the steel slag can flocculate and agglomerate partial small molecular pollutants in the rainwater, the manganese sand filter material has a large surface area and sewage interception capability, and can effectively remove pollutants such as iron, manganese, arsenic and the like in the rainwater, the quartz sand and the activated carbon filter material also play a certain role in filtration, and can also prevent the whole fine filter layer from hardening.
The invention relates to rainwater treatment and recycling integrated equipment, which overcomes the defects of long process, complex structural equipment, large occupied area, poor treatment effect and the like of the conventional rainwater treatment and recycling system.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
