Membrane treatment process device and processing method thereof

Abstract

The invention discloses a membrane treatment process device and a processing method thereof. The device comprises a low-energy-consumption micro-nano bubbling water generating device, a water inlet pipe, a bottom valve, a raw water pool, a one-way valve, an ultrafiltration water inlet pipe and an ultrafiltration membrane module. The device has the advantages that the adopted low-energy-consumption micro-nano bubbling water generating device substitutes a membrane process water inlet centrifugal pump process, so that membrane water inlet is not merely water but is micro-nano bubbling water containing a great number of micro-nano bubbles, a great number of micro-nano bubbles exist in the bubbling water, scaling substances cannot adhere easily, original scaling substances are even gradually peeled by the micro-nano bubbles, chemical agents such as antisludging agents do not need to be added, back-flushing is not needed, the service life of a membrane is greatly prolonged, water producing capability is enhanced, air inflow amount is adjustable, the vapor-liquid ratio can be adjusted to 20-100%, by means of the one-way valve, the bubbling water cannot backflow from the ultrafiltration membrane module, it is guaranteed that the water pressure in the ultrafiltration membrane module is stable, and the filtering effect of the ultrafiltration membrane module is guaranteed.

Description

technical field [0001] The invention relates to a membrane treatment process method, in particular to a membrane treatment process device and a treatment method thereof, belonging to the field of membrane treatment equipment. Background technique [0002] Ultrafiltration membranes are widely used in industry and have become one of the new chemical and water treatment unit operations. Used in separation, concentration, purification of biological products, pharmaceutical products and food industry; also used in terminal treatment devices in blood treatment, wastewater treatment and ultrapure water preparation. With the advancement of technology, the ultrafiltration membrane's screening function will be improved and strengthened, and its contribution to human society will also become greater and greater. In the past two years, in order to obtain higher dissolved oxygen efficiency, micro-nano bubble generation technology has been widely used in water treatment, aquaculture, ric...

AI Technical Summary

Problems solved by technology

However, the micro-nano bubble generating equipment in the prior art generally has the following deficiencies: First, most of its core components simply use gas-liquid mixing pumps or centrifugal pumps. Although the dissolution efficiency can reach 80-100%, the air intake is only 8 -10%; Second, although the pumps can be used in series to increase the suction capacity, it increases the capital investment and power of the equipment, which increases the operating cost of the equipment; Third, the general flow rate of micro-nano bubble equipment is too small to operate in a relatively small Fourth, in order to reduce costs and save energy, the head is generally low, and it has been used in agricultural aeration and river aeration, but it cannot be applied in water treatment and membrane treatment.
