It is secondary that hyperfiltration membrane assembly is entered by pipeline；It is heated up by heat exchanger to cleaning solution, improves cleaning effect；Cleaning solution is recycled back to
Extraction liquid storage tank (for purge tank) is flowed to, when cleaning can control circulation and soaking time.Cleaning solution be finally discharged to wastewater disposal basin into
Row processing.
(2) hyperfiltration membrane assembly on-line cleaning: when normal work, backwash and air purge can be periodically carried out, when backwash beats
Backwashing pump is opened, other pumps and valve are closed, and anti-in this way (punching) washes the opening of the valve on pipeline, are backwashed with refined liquid, thoroughly
It crosses liquid and returns to extraction liquid storage tank；When air purge, other pumps and valve are closed, valve and backwash pipeline in this way on opening air compressor machine tracheae
On valve.Generally, it operates normally 30-45 minutes, backwash and air purge time are 30-60 seconds general.
(3) reverse osmosis membrane assembly and STRO membrane module clean (i.e. RO and STRO component cleans offline) offline: opening cleaning
The valve of water tank opens cleaning pump, not only can clean reverse osmosis membrane assembly and STRO membrane module by the output end of cleaning pump.
And hyperfiltration membrane assembly is arrived after entering by the output end cleaning solution of cleaning pump, it is heated up, is improved to cleaning solution by heat exchanger
Cleaning effect；For cleaning solution circulating reflux to extraction liquid storage tank (for purge tank), when cleaning, can control circulation and soaking time.Clearly
Washing lotion is finally discharged to wastewater disposal basin and is handled.
And flushing pump is set through the output end of liquid storage tank, the output end connection STRO membrane module of flushing pump is opened and is rinsed
The valve of the output end of pump cleans STRO membrane module.
The above is only a specific embodiment of the invention, it is noted that is come for those of ordinary skill in the art
It says, without departing from the principle of the present invention, several deformations can also be carried out to technical solution of the present invention or equally replaced
It changes, these also should be regarded as belonging to the scope of protection of the present invention.
