Matter mean intensity value.
The Initial Runoff of above-mentioned water quality and liquid level coordinated signals is collected and separate system, step when use as shown in Figure 3
Rapid and logic works：
State one：When rainfall not occurring, whole system is in original state, electronic flowmeter 42, multi-parameter water quality probe
41 and liquid-level probe 43 be in initial default state (dormant state is set in the present embodiment), motor-driven valve 25 and water pump 26
It is closed；
State two：When rainfall occurs, occurs flow in rainwater collection collector 13, electronic flowmeter 42 starts acquisition and enters rainwater
Flow information in collecting pipe 13, while multi-parameter water quality probe 41 and liquid-level probe 43 are acquired and are sent to PLC controller 31
Signal；
Step 1：Multi-parameter water quality probe 41 is calculated by PLC control modules 3 by on-line analysis water quality index and generates 5-
Mean concentration in 10min, by logical operation, the opening and closing that PLC control modules 3 control motor-driven valve 25 reaches control initial rainwater diameter
The effect of flow direction realizes rainwater shunting, specifically：When water quality index is higher than the limit value of default, pass through signal wire 33
PLC control modules 3 are transmitted information to, control motor-driven valve 25 is opened, and rainfall runoff passes through initial rainwater runoff collecting pipe at this time
24 intake to the collecting bin 21 of initial rainwater collection device 2；When water quality index is less than the limit value of default, motor-driven valve is controlled
25 close, and rainfall runoff is discharged directly into next processing unit by runoff delivery pipe 24 at this time；
Step 2：After initial rainwater runoff enters initial rainwater collection device 2, the water level in collecting bin 21 will be increased slowly,
And water pump 26 is opened in due course to control water level in collecting bin 21, specifically：When water level is less than minimum set by liquid-level probe 43
When water level reference value, water pump 26 is in and shuts down state, and water level is made to continue to rise；When water level higher than lowest water level reference value, be less than
When peak level reference value, PLC control modules 3 is transmitted information to by signal wire 33, and then control water pump 26 and open, passed through
Water-supply-pipe 27 supplies water to follow-up equipments such as rainwater treatment units；When water level rises to the peak level reference of the setting of liquid-level probe 43
When value, water pump 26 keeps working condition, until water level is higher than after peak level reference value, liquid-level probe 43, which is triggered, leads to signal
It crosses signal wire 33 and is transferred to PLC control modules 3, control motor-driven valve 25 is closed, and stops intaking to initial rainwater collection device 2, together
When next unit is discharged directly by initial rainwater runoff delivery pipe 24, passing through linked manner reduces water in collecting bin 21
Position, until water level reenters normal separate drain state after being less than peak level reference value；
State three：Rainfall stop after, electronic flowmeter 42 by acquire rainwater collection collector 13 in flow information data,
The stalling of motor-driven valve 25 is set to return to original state；Water pump 26 and liquid-level probe 43 continue working whithin a period of time：When initial stage rain
When water level in the collecting bin 21 of water collecting device 2 is between highest liquid level and the setting reference value of minimum liquid level, pass through PLC
Control module 3 controls water pump 26 and works on；When the water level in collecting bin 21 is less than the setting reference value of minimum liquid level, pass through
PLC control modules 3 control water pump 26 and are stopped, and whole system returns to original state, and wait for catchment next time.
In conclusion collecting and shunting system using the water quality of above-mentioned technical proposal and the Initial Runoff of liquid level coordinated signals
System carries out accurate, quantitative collection to initial rainwater and shunting is handled, reduces municipal sewage pipe network load, promote city water ring
The promotion of border quality.
