Problems solved by technology

However, after the rainwater falls to the ground and stays underground, it will carry a considerable amount of dust or pollutant particles, and the inflowing rainwater needs to be purified to obtain the above-mentioned purposes. In the prior art, the collection module itself only has water storage capacity. All of them are equipped with a filter device at the entrance of the collection module to achieve the purpose of pre-purification. This process is relatively complicated and increases the manufacturing cost.

Abstract

The invention provides a preliminary cleaning rainwater collection module. The preliminary cleaning rainwater collection module is prepared from, by weight, 15-20 parts of an ethylene-vinyl acetate copolymer, 8-14 parts of 2-methyl methacrylate, 15-20 parts of deionized water, 11-15 parts of water soluble acrylic resin, 14-17 parts of nanometer activated carbon, 1-3 parts of acetamide, 2-4 parts of antioxidant, 5-9 parts of calcium carbonate, 4-7 parts of carbon black, 6-12 parts of kieselguhr and 1-2 parts of a dispersing agent. The rainwater collection module can perform preliminary cleaning on rainwater in the water storage process, can remove particulate matter contained in rainwater, and saves the cost. An implementation method is simple and has the wide application prospect.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a pre-purification rainwater collection module and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the shortage of water resources, environmental pollution, ecological damage and other problems continue to intensify. Rainwater, as a clean, economical and convenient green water source, has received more and more attention. The rainwater collection module is a part of the rainwater collection and utilization system. It is a combination of several rainwater collection module units to form an underground storage tank. The rainwater collection module can effectively store the collected rainwater. The stored water resources can be used for flushing toilets, cleaning roads, watering lawns, replenishing water features, and even circulating cooling water and firefighting water after treatment. However, after the rainwat...
