Comprehensive water treatment system

Abstract

The invention relates to a comprehensive water treatment system, which comprises two external compression type ultrafiltration membrane filters, three activated carbon water purifiers and an ultraviolet sterilizer, wherein a cross-flow discharge port, a water production port and a raw water inlet are formed in the first external compression type ultrafiltration membrane filter; the three activated carbon water purifiers are sequentially connected in series to form a three-stage activated carbon water purification system; a water inlet of the first activated carbon water purifier is communicated with the water production port of the first external compression type ultrafiltration membrane filter; the ultraviolet sterilizer is arranged between the second and third activated carbon water purifiers, and a water inlet and a water outlet of the ultraviolet sterilizer are communicated with a water outlet of the second activated carbon water purifier and a water inlet of the third activated carbon water purifier respectively; a cross-flow discharge port, a water inlet and a pure water outlet are formed in the second external compression type ultrafiltration membrane filter, and the water inlet is communicated with a water outlet of the third activated carbon water purifier. The system is compact in structure and convenient to mount, disassemble and carry, has good purification effect, can be used in a water source region, arranged on a kitchen vehicle or another vehicle and transported to a specified site for use, and can be widely applied to various places with requirements on the supply of drinking water.

Description

technical field [0001] The invention relates to a water purification system, in particular to a comprehensive water treatment system suitable for purifying raw water in the field. Background technique [0002] In recent years, natural disasters have occurred frequently all over the world. Natural disasters such as earthquakes and floods have caused huge losses to the country and the people. When natural disasters occur, the main characteristics of surface water quality are high turbidity, excessive microorganisms, high suspended solids, and peculiar smell of water, which are not suitable for people to drink directly. Therefore, how to provide safe and hygienic drinking water to the disaster area in time is an important link to ensure the health and life of the people in the disaster area. [0003] Existing water purification equipment mostly uses a single ultrafiltration membrane to purify water. After filtering the raw water through the ultrafiltration membrane, there may ...

Problems solved by technology

However, since the above two types of water purification equipment are separate and independent in structure, they need to be assembled before they can be used. The production cost is relatively high, and the equipment is large in size, which is inconvenient for transportation and cannot meet the emergency needs of the disaster area.
