   During fine day, the cut-off equipment for being arranged on the first water outlet of the first shunting well is in current floe condition, or described first point When stream well is slot type, in current floe condition；First flow control device and second flow control device are in opening；Rainwater The sanitary sewage of main misconnection hybrid junction enters the second shunting well, is controlled by the first delivery port and first flow of the second shunting well Device is flowed into and regulated and stored facility, and the sanitary sewage in facility of regulating and storing flows to sewage treatment plant by Action of Gravity Field and handled, and works as water When amount is exceeded towards the maximum inflow-rate of water turbine for cutting dirty pipe of sewage treatment plant, sanitary sewage can store in facility of regulating and storing, when regulating and storing When water in facility reaches maximum moisture storage capacity, first flow control device is closed, sanitary sewage is by the of the second shunting well Two delivery ports and second flow control device flow into online processing unit, and the sanitary sewage after being handled through online processing unit is again It is directly discharged to Storm-water sewer；

   During rainfall, the cut-off equipment for being arranged on the first water outlet of the first shunting well is in current floe condition, or described first point When stream well is slot type, in current floe condition；First flow control device and second flow control device are in opening；Rainwater The sanitary sewage of main misconnection hybrid junction is dirty with entering the mixing that the rainwater of Storm-water sewer is formed through the inlet for stom water along town road Water enters the second shunting well, flows into facility of regulating and storing by the first delivery port and first flow control device of the second shunting well, adjusts Combined sewage in storage facility flows to sewage treatment plant by Action of Gravity Field and handled, and leads to sewage treatment plant when water exceedes The maximum inflow-rate of water turbine for cutting dirty pipe when, combined sewage can store in facility of regulating and storing, when the water in facility of regulating and storing reaches maximum During moisture storage capacity, first flow control device, second delivery port and second flow control of the combined sewage by the second shunting well are closed Device processed flows into online processing unit, and the combined sewage after being handled through online processing unit is directly discharged to Storm-water sewer again；

   During rainfall, when water exceedes the maximum processing capability of online processing unit, second flow control device is closed, is arranged on The cut-off equipment of first water outlet of the first shunting well is in opening, or when first shunting well is slot type, works as institute Combined sewage is stated when the liquid level of slot type shunting well is more than the height of groove, combined sewage is directly discharged into natural water.
10. 10. control method according to claim 9, it is characterised in that when the system includes mechanical pump, the control Method includes：

    During fine day, the cut-off equipment for being arranged on the first water outlet of the first shunting well is in current floe condition, or described first point When stream well is slot type, in current floe condition；First flow control device and second flow control device are in opening；Rainwater The sanitary sewage of main misconnection hybrid junction enters the second shunting well, is controlled by the first delivery port and first flow of the second shunting well Device is flowed into and regulated and stored facility, and the sanitary sewage in facility of regulating and storing is pumped into sewage treatment plant by machinery and handled, and works as water When amount exceedes the maximum stream flow of pump row, sanitary sewage can store in facility of regulating and storing, when the water in facility of regulating and storing reaches maximum During moisture storage capacity, first flow control device, second delivery port and second flow control of the sanitary sewage by the second shunting well are closed Device processed flows into online processing unit, and the sanitary sewage after being handled through online processing unit is directly discharged to Storm-water sewer again；

    During rainfall, the cut-off equipment for being arranged on the first water outlet of the first shunting well is in current floe condition, or described first point When stream well is slot type, in current floe condition；First flow control device and second flow control device are in opening；Rainwater The sanitary sewage of main misconnection hybrid junction is dirty with entering the mixing that the rainwater of Storm-water sewer is formed through the inlet for stom water along town road Water enters the second shunting well, flows into facility of regulating and storing by the first delivery port and first flow control device of the second shunting well, adjusts Combined sewage in storage facility is pumped into sewage treatment plant by machinery and handled, when water exceedes the maximum stream flow of pump row When, combined sewage can store in facility of regulating and storing, and when the water in facility of regulating and storing reaches maximum moisture storage capacity, close first flow Control device, combined sewage flow into online processing dress by the second delivery port and second flow control device of the second shunting well Put, the combined sewage after being handled through online processing unit is directly discharged to Storm-water sewer again；

    During rainfall, when water exceedes the maximum processing capability of online processing unit, second flow control device is closed, is arranged on The cut-off equipment of first water outlet of the first shunting well is in opening, or when first shunting well is slot type, works as institute Combined sewage is stated when the liquid level of slot type shunting well is more than the height of groove, combined sewage is directly discharged into natural water.
