6. a kind of ship desulfuration waste water treatment process, it is characterised in that specifically includes the following steps:
S1, the water feelings for first requiring according to preset mixing, and utilizing radar level switch (4) detection mixer (21) internal
Then condition controls the start and stop of feeder (5) and water power solenoid valve (6) to control inflow；Medicament is being sent into mixer
(21) before, medicament is thermally dried using heater (2), is re-fed into mixer (21), then using on mixer (21)
The first blender (7) be stirred soluble chemistry medicament；
S2, the first pneumatic operated valve (10) are opened, the desulfurization wastewater of ship flows into chemical reaction groove (22) by waste water access tube (9)
Interior, whole system starts at this time, and mixed chemical agent is pumped into air levitation unit (1-2) and dynamic by dosing pump (8)
In filter element (1-3), it is stirred effect using second blender (11) on chemical reaction groove (22) top, then by molten
Gas pressure pump (12) discharges minute bubbles and micro-bubble into air floatation machine water, and anti-by liquidometer (24) real-time detection chemistry
The level condition for answering slot (22) internal, Slag Scraping Device (13) periodically scrape dross to slag charge case, and are sent by dynamic elevator pump (14)
Dynamic filtration unit (1-3), clear water are emitted by Dynamic Emission pump (16)；
S3, the top dynamic filtration unit (1-3) set blender, and dross enters after dynamic filtration unit (1-3) due to joined
It learns medicament to be sufficiently stirred, be dehydrated after being squeezed by folded spiral shell driving machine (18) driving lamination (19), after filtrate reaches certain liquid level
It is returned to by filtrate elevator pump (20) in the chemical reaction groove (22) of air levitation unit (1-2), sludge cake after extruding exists
Mud discharging mouth is uniformly processed after being collected storage.
