Why can t rainwater be stored for a long time?

Water also has a shelf life, and at present, water cannot be strictly acidic as pure, and there will be microorganisms, pathogenic bacteria, and various impurities.

In particular, surface runoff, due to its scouring effect on the road surface contains a large number of polluting substances, when the rainwater is collected, microorganisms will use the nutrients in it to multiply, when the dissolved oxygen in the container is consumed, anaerobic bacteria will multiply a large amount of ammonia and hydrogen sulfide, forming a foul odor, generally speaking, in a closed opaque container, the odor will reach the maximum value within 72 hours.

Anaerobic bacteriaAnaerobic bacteria are a large group of bacteria, obligate anaerobic, that must grow in an anaerobic environment. Anaerobic bacteria are widely distributed in nature and in humans and animals. Non-spore anaerobic bacteria mainly exist in human and animal bodies, especially in the intestines, oral cavity, upper respiratory tract and urinary tract, etc., and together with aerobic bacteria and facultative anaerobic bacteria, they constitute the normal flora of the body.

In the normal flora, anaerobic bacteria usually have an absolute predominance. Under normal circumstances, the protection of the microbiota is relatively balanced, such as long-term use of broad-spectrum antibiotics, hormones, immunosuppressants, etc., the occurrence of dysbiosis, or the weakening of the body's immunity, can lead to endogenous anaerobic bacterial infection.

Because it rains for a long time, bacteria can grow, so it cannot be stored for a long time.

Rainwater is naturally weak acidic and suitable for most flowers and plants, but a few plants that like alkaline can not be watered with rainwater for a long time, such as chrysanthemums, cypress, pomegranates, etc.

Food has a shelf life, water also has a shelf life, at present, water can not be strictly acid as a pure substance, which will have microorganisms, pathogenic bacteria, and various impurities.

To put it simply, rain is also a type of living organism, and if you think about it, what kind of creature does not die and does not expire? People are oxidized!

Because the sun and water are circulating, with sunlight the water evaporates, and then when it gets cold, it collides with the atmosphere and forms small droplets of water that come down.
