Step 1: debugging aquifer yield, open motorized valve 9, observe sewage works drain discharge meter, when water displacement during greater than the sewage works design discharge, the rotation floating drum is regulated bolt 6-1, adjusts floating drum 3 downwards, drain box 5 come-ups, cloth weir board 4 draft amounts reduce, and namely cloth weir board 4 degree of depth of descending point to dive beneath the water most reduces, and drain discharge reduces, otherwise, to adjusted floating drum 3, increase the draft of cloth weir board 4, drain discharge increases, equal design discharge until regulating drain discharge, fastening adjustment locknut 6-3, the relative position of maintenance floating drum 3 and cloth weir board 4 guarantees stable aquifer yield;
Step 2: in the use, when settling tank 10 flooding quantitys equaled the drain box drain discharge, drain box 5 was stabilized on the certain liquid, when less than drain discharge, settling tank 10 liquid levels constantly descend, drain box 5 can constantly descend thereupon, to lower retainer 13, namely during lowest water level, inductance approach switch a2 is near lower retainer 13, lower retainer 13 is sent signal, closes motorized valve 9, stops draining, drain box 5 namely stops, along with continuing water inlet, liquid level rises, and settling tank 10 liquid levels constantly rise, drain box 5 can constantly rise thereupon, during supreme stopper 16, namely during top water-level, inductance approach switch b18 is near upper limit device 16, upper limit device 16 sends signal, deliver to sewage works pump sump sump pump and and motorized valve 9, make its termination of pumping, stop to send water and opening motorized valve 9 to settling tank, the beginning draining, drain box 5 is along with the continuation of draining, and liquid level begins to descend, and has guaranteed that liquid level is no more than top water-level.
Beneficial effect
Facility investment, operation expense every the quantitatively unsteady unpowered energy consumption of discharging device of duckweed formula, saving submersible pump are low; Need not safeguard almost do not have maintenance cost after disposable the adjusting; And because the water of discharging is the clear liquid of settling tank all the time, its effluent quality is better than the water that submersible pump is discharged, and then has alleviated the load of next stage treatment facility.
Because isometric every quantitatively float floating drum and the drain box of discharging device of duckweed formula, the water that enters drain box enters drain box by turning on the floating drum bottom, so greasy dirt or the drift on top layer separated the assurance effluent characteristics by floating drum during draining.
Quantitatively floating every the duckweed formula, to have the surplus of adjusting big for discharging device, and a covering device need not to increase the needs of the quantitative discharging of the advection oil partiting precipitation pool that facility investment can solve the treatment capacity that varies in size.
Every the quantitatively unsteady discharging device of duckweed formula, fixing solid firm to the slideway upper holder from base to the support slideway base, the jam of avoiding support slideway generation deformation to cause drain box up and down reciprocatingly to move.
Preset clearance and drain box orienting sleeve port angle α between support slideway and drain box orienting sleeve=15 ° can effectively avoid the jam that drain box slides up and down.
Each draining expansion pipe junction is embedded with the O RunddichtringO and guarantees sealing, and there is boss at the sealing-ring place, can prevent effectively that expansion pipe from being prevented disconnection problem by the pulling force of floating drum.
When reaching the lower limit water level, the water of settling tank can stop automatically.
Adjusting by cloth weir board altitude mixture control and float-level height can realize quantitative draining, can be to floating drum upper-lower position fine setting by the floating drum setting device, and fine setting operation is simple.
