Description
Technical Field
The utility model particularly relates to an intelligent water supply ultrafiltration device.
Background
The rural drinking water is safe, namely, residents in rural areas can timely and conveniently obtain sufficient, sanitary and affordable life drinking water. Sanitary standards for domestic drinking water (GB 5749-2022) specify strict sanitary requirements for the quality of domestic drinking water, namely: (1) good sensory properties: transparent, colorless, odorless and free of foreign odor and macroscopic objects; (2) epidemiologically safe: does not contain pathogenic microorganisms and parasitic ova; (3) the chemical composition is harmless to human: the chemical substances contained in the water do not cause acute poisoning, chronic poisoning and long-term harm to human bodies. However, the rural water supply still faces a plurality of problems due to various topography and topography, complex geological structure and uneven development among areas in China.
The existing integrated equipment for rural water supply mainly adopts a main type of immersion ultrafiltration filtration Cheng Heqi floating filtration and ceramic membrane filtration process 2, and takes ultrafiltration equipment as a main stream. The method comprises the following steps:
(1) Immersed ultrafiltration filtration process
The immersed ultrafiltration raw water enters an ultrafiltration membrane pool through a water inlet pipe and a water inlet control valve, a water production pipeline is integrated below the membrane pool, the membrane pool is lifted, water to be filtered permeates through a membrane wall from the outer side of a hollow fiber membrane through siphon action, and the water is collected in a water collecting pipe. All produced water in each membrane pool is collected into a produced water main pipe and enters the next treatment process or a clean water pool. The membrane pond needs to be emptied for backwashing after each filtration period, and chemical cleaning is carried out for about 3 months, and about 3 days are required each time.
Drawbacks of the submerged ultrafiltration process are:
a) The membrane pool needs to be emptied during backwashing, so that the water consumption is high;
b) The on-site lifting condition of the membrane component is not met, the single-curtain membrane component is difficult to detach and clean and can only be cleaned in situ, manual climbing and dosing are needed, and the risk of high-altitude falling is caused;
c) The cleaning time is long, and the daily life water of residents is influenced;
d) The membrane tank water tank is positioned outdoors and needs manual welding, the whole peripheral pipeline is connected more complicated, and the field workload is larger;
e) The membrane tank is large, is not easy to transport and needs to be assembled on site;
(2) Air-float filtering and ceramic membrane filtering process
The raw water is filtered by air floatation to intercept part of suspended matters in the water, and then filtered by ceramic membrane to intercept ions in the water, so that the water quality reaches the water requirement.
The air floatation filtering and ceramic membrane filtering processes have the defects that:
a) The ceramic membrane has higher cost and the whole equipment has higher cost;
b) The ceramic membrane is heavy, and the equipment is inconvenient to transport;
c) The ceramic membrane has low packing density, so the occupied area of the equipment is large.
