Embodiment

[0041] Please refer to figure 1, a water treatment ultrafiltration system, comprising: a raw water pool 10, two sets of ultrafiltration membrane filtration systems 20a and 20b arranged side by side, a produced water pool 30, a backwash system 40 and two sets of chemical cleaning systems 50.

[0042] The raw water pool 10 communicates with the ultrafiltration membrane filtration systems 20a and 20b respectively through the raw water input pipe 11, and the raw water is divided from the raw water input pipe 11 into two sets of ultrafiltration membrane filtration systems 20, so that the two sets of ultrafiltration membrane filtration systems 20 are formed Constellation. The raw water input pipe 11 is sequentially provided with a raw water pump P04, a security filter 12 and a water inlet valve F01 along the direction from the raw water pool 10 to the ultrafiltration membrane filtration system 20. In this embodiment, the security filter 12 is a laminated filter.

Abstract

The invention discloses a water treatment ultrafiltration system, and belongs to the technical field of water treatment. The water treatment ultrafiltration system comprises a raw water tank, at leasttwo groups of ultrafiltration membrane filtration systems arranged in parallel, a water production tank and a backwashing system, wherein the raw water tank is communicated with the ultrafiltration membrane filtration systems, the ultrafiltration membrane filtration systems are communicated with clear water output pipes respectively, one end of each clear water output pipe is communicated with the water production tank, and the other end of the clear water output pipe is communicated with the backwashing system; a plurality of the ultrafiltration membrane filtration systems are communicated by the backwashing system and the water production tank and are arranged in parallel accordingly. Interactive backwashing can be realized between the two ultrafiltration membrane filtration systems bythe backwashing system, a backwashing water tank does not need to be arranged, water resources are saved, and secondary pollution to ultrafiltration membranes due to the influence of respiration of the water tank is avoided.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment ultrafiltration system. Background technique [0002] In recent years, membrane separation technology has been widely used in the fields of electric power, metallurgy, petroleum and petrochemical, medicine, food, water source treatment, municipal engineering, sewage reuse and seawater desalination by virtue of high separation efficiency, low energy consumption, and simple operation. . In addition to being used in some of the above fields, ultrafiltration membranes, as a high-precision, energy-saving, and environmentally friendly filtration technology, have strong application scalability. It can be combined with one or more technologies to replace traditional crafts and promote traditional technology and industrial upgrading. In water treatment, the separation and filtration of various suspended solids, macromolecular particles and colloidal pollutants ...
