Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Embodiment:
Referring to Fig. 1 and Fig. 2, this utility model provides a kind of technical scheme: at a kind of petrochemical effluent based on PLC
Reason device, enters device (1), clarifier-tank (2) including sewage pump and controls computer (3), and described sewage pump enters device (1) by sewage pump
(4) form with sewage conduct (5), between described sewage pump (4) and sewage conduct (5), be additionally provided with anti-dry current limliting electromagnetic valve
(15), described anti-dry current limliting electromagnetic valve (15) controls switch by controlling computer (3), at sewage conduct (5) and clarifier-tank
(2) junction is provided with flow detector (6), and described clarifier-tank (2) includes oil interceptor (7), flotation tank (8) and biochemistry pool
(9), described oil interceptor (7), flotation tank (8) and biochemistry pool (9) be mounted on water gauge (10), flow detector (6) and after
