s4: the filtered purified water flows into a degasser (10) from a secondary DTRO group (4) through a shutoff valve (7) and flows into a clean water tank after being deodorized;
s5: when the DTRO membrane assembly (5) needs to be cleaned, the circulating pump (3) is reversely rotated, meanwhile, the driving motor (607) on the check valve body (6) is started, the check direction of the check valve body (6) is changed, cleaning liquid flows in from an external cleaning tank at the moment, reverse circulation is carried out in the primary DTRO group (2) and the secondary DTRO group (4), and back flushing is carried out on the membrane (506).
