Problems solved by technology
[0003] After long-term operation of the membrane separation device, colloids, metal oxides, bacteria, organic matter, scale and other substances will accumulate on the concentrated water side of the membrane, causing membrane fouling
The formation of membrane fouling leads to a decrease in flux and an increase in the pressure difference between the inlet and outlet of the module, which affects the economics of the membrane separation device
Membrane fouling is a common problem in the application of membrane separation technology, and has become the biggest obstacle to the long-term stable operation of membrane separation systems

The invention belongs to the technical field of cleaning agents, and particularly relates to an acid cleaning agent of a membrane of a disc-tube membrane separator and a preparation method thereof. The invention provides an acid cleaning agent of a membrane of a disc-tube membrane separator and a preparation method thereof; the acid cleaning agent can quickly remove dirt on the membrane of the membrane separator and is highly practical. The acid cleaning agent of the membrane of the disc-tube membrane separator is characterized by being prepared from the following raw materials by mass percent: 25.7% of citric acid, 0.05% of preservative Huake 88, 3.30% of aqueous ammonia and 71.00% of pure water. The acid cleaning agent is applicable to the field of sewage treatment.
Description
technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to an acidic cleaning agent for a diaphragm of a disc-tube membrane separation device and a preparation method thereof. Background technique [0002] With the increasing shortage of water resources in our country, large-scale coal chemical enterprises have more sewage to be recycled. The membrane of the disc-tube membrane separation device can effectively desalinate, and it is often used as a check process unit for water treatment to meet the standards. a wide range of applications. [0003] After long-term operation of the membrane separation device, colloids, metal oxides, bacteria, organic matter, scale and other substances will accumulate on the concentrated water side of the membrane, causing membrane fouling. The formation of membrane fouling leads to a decrease in flux and an increase in the pressure difference between the inlet and outlet of the module,...
