Rural water-quality-based water supply and purification integrated system for energy conservation and emission reduction

Abstract

The invention discloses a rural water-quality-based water supply and purification integrated system for energy conservation and emission reduction. The rural water-quality-based water supply and purification integrated system for energy conservation and emission reduction comprises a pretreatment system (2), a heavy metal ion treatment system (5), a water softening system (9) and an ultrafiltration system (14), wherein the water softening system (9) comprises an activated carbon filter layer (10) and a resin softening filter layer (12); the heavy metal ion system (5) consists of an adsorptionmain body (6), a filter screen (7) and a carrier (8); and the adsorption main body (6) consists of at least three adsorption layers which are successively connected in a stacked manner or has an integrated cylindrical structure; and an adsorbing material comprises KDF55 alloy or KDF55 alloy and one or more of graphene oxide, activated carbon, attapulgite clay and polyacrylic acid. Water-quality-based water supply can be realized, heavy metal ions, microorganisms and other impurities in water can be removed effectively, water source purification is classified into irrigation water, toilet washing water, washing water and drinking water, the system is simple to operate and low in cost, and resources are saved.

Description

technical field [0001] The invention relates to the field of water purification, in particular to an integrated rural water supply and purification system for energy saving and emission reduction. Background technique [0002] Water is the source of life, an important part of human and animal body fluids, and a necessary condition for the growth of animals and plants. With the development of rural economy, the abuse of waste batteries, industrial waste water, domestic sewage and pesticides pollutes daily water, drinking water and irrigation water to varying degrees, resulting in the continuous enrichment of toxic substances in agricultural products and endangering human health. Due to the pollution of rural water sources, irrigation water is also polluted to varying degrees, resulting in the accumulation of heavy metals in agricultural products, such as chromium, platinum, lead and other toxic substances, which indirectly endanger the health of consumers. [0003] At presen...

Due to the pollution of rural water sources, irrigation water is also polluted to varying degrees, resulting in the accumulation of heavy metals in agricultural products, such as chromium, platinum, lead and other toxic substances, which indirectly endanger the health of consumers

[0003] At present, most of the pure water machines sold on the market in my country are the ratio of pure water to purified concentrated water. The ratio of large-scale machines is 1:1, and that of small machines is 1:4. The purified concentrated water of most pure water machines is drained, causing Waste of water resources, high cost of pure water

Most water purifiers use tap water as the water source, with good water quality and stable water pressure, but the water pressure in rural areas cannot be guaranteed. Ordinary water purifiers are expensive to use in rural areas and have poor applicability. In the end, only one kind of drinking water can be obtained, and the daily water and irrigation water still contain many toxic substances. These shortcomings prevent ordinary water purifiers from being widely used in rural areas.
