Plate ceramic membrane filtration performance testing device and testing method

Abstract

The invention discloses a plate ceramic membrane filtration performance testing device. The device comprises a water production tank, a raw water tank, a membrane pool, a water production pump, a water conveying pump, a raw water pump, an analyzer and a control device; a filtering device is arranged in the membrane pool; the filtering device comprises a plurality of filtering membrane groups; eachfiltering membrane group comprises a flat plate ceramic membrane and a clamp for clamping the corresponding flat plate ceramic membrane; a raw water pipeline is arranged between the raw water pump and the raw water tank; a sewer pipeline is arranged between the bottom of the raw water tank and the water conveying pump; a water conveying pipeline is arranged between the membrane pool and the waterconveying pump; a first water production pipeline is arranged between the membrane pool and the water production pump, and a second water production pipeline is arranged between the water productionpump and the water production tank; a first backwashing pipeline is arranged between the bottom of the water production tank and the water production pump, and a second backwashing pipeline is arranged between the water production pump and the membrane pool. The plate ceramic membrane filtration performance testing device can quickly evaluate the performance of the plate ceramic membranes in to-be-treated wastewater.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a device for evaluating the filtration performance of a flat ceramic membrane and a method for testing the filtration performance of a flat ceramic membrane by using the device. Background technique [0002] At present, flat ceramic membrane separation equipment is more and more used in municipal tap water, seawater desalination, petrochemical, food, medical and other fields. Usually, small tests and pilot tests are first required in the application development process to optimize the performance of flat ceramic membranes. Performance parameters such as operating flux, pollution resistance, backwash, strength, and aeration in a specific environment verify the filtration performance of flat ceramic membranes. Since the flat ceramic membrane is an emerging membrane material in recent years, the country has no recommended standards for related products. There are...

AI Technical Summary

Problems solved by technology

Since the flat ceramic membrane is an emerging membrane material in recent years, the country has no recommended standards for related products. There are many types of flat ceramic membranes on the market, and the product quality varies. Traditional flat ceramic membrane filtration devices generally refer to ceramics of one size. Membrane design, for other manufacturers of flat ceramic membrane products can not be installed test

In addition, the traditional flat-panel ceramic membrane filtration device is used for water quality monitoring in the way of manual on-site sampling and inspection, which consumes manpower and time. Not only is the operation cumbersome, but there is also the possibility of secondary pollution of the water sample during the sampling process. Data processing also faces problems such as inability to track in real time
