Description

Novel three-stage water purifying device using hydrate gel
Technical Field
The utility model relates to a purifier technical field, concretely relates to use novel tertiary purifier of hydrate gel.
Background
In the current China, the scale and area of cities are getting bigger and bigger, and even if tap water treated by city water plants is pure and meets the requirements of national standards on drinking water, the pipeline examination is needed before the purified water reaches households because the distance between the city water plants and user terminals is far away. Tap water plants are sometimes far away from the user end, and tap water usually passes through a long water pipeline before reaching the user end, so that microbial pollution, heavy metal pollution and organic matter pollution are bred in the water pipeline. The urban layout of China is too fast, so that the local pipe network which is as reasonable as possible and distributed integrally is difficult to guarantee to be unreasonable, a plurality of pipe networks are adjacent to the sewage discharge pipe, sewage permeates into the tap water pipe, and cross pollution is caused. Contamination from water storage tanks and pipe leaks can cause microbial contamination, heavy metal contamination and organic contamination. In addition, the water storage tanks of old and broken small cells are more seriously aged than the water tanks and part of the water storage tanks are not cleaned in time, so that a large amount of bacteria, microorganisms, heavy metal ions and the like are bred. And sometimes the water tank is not sealed tightly, possibly impurity gets into, and the potential safety hazard is just secret and lifelike.
