7. from broken flotation device drain valve (1-15), double flotation device drain valve (2-13) and triple flotation device drain valve (3-13)
The plastics emitting and the mixture of flotation fluid carry out separation of solid and liquid respectively, and the flotation fluid after separation of solid and liquid is by aerobic contact
Oxidation pond water inlet pipe (4-1) enters the middle and lower part in aerobic contact oxidation pond, uniform cloth in the presence of water distribution pyrometric cone (4-2)
Water, aerobic contact oxidation pond aeration plate produces substantial amounts of microbubble, and dissolved oxygen sensing regulation device regulates and controls drum according to oxygen capacity
Blower fan work it is ensured that dissolved oxygen in aerobic contact oxidation water is more than 2mg/L, the water after process pass through downflow weir (4-5) and
Outlet pipe enters clear water reserviors, and the clear water in clear water reserviors pumps into broken flotation device flotation fluid interpolation mouth by water pump, double flotation device floats
Liquid interpolation mouth and triple flotation device flotation fluid is selected to add mouth and carry out reuse.
