Background
The water environment capacity is smaller, the fluidity is poor, and the self-cleaning capability is poor, so that the water environment is a common problem of the ecological landscape water body of the constructed wetland in most urban residential communities. In addition, domestic property management companies generally lack scientific management, and the closed slow-flow landscape water body is easy to become a receptor of domestic sewage, rainwater and garbage. The water body is extremely easy to breed mosquitoes, generates eutrophication, becomes turbid, even blackens and smells, and seriously influences the functions of the landscape water body.
According to research, the phenomenon of rain and sewage mixed connection commonly exists in old communities in China at present. In some old communities, due to the fact that the requirements of relevant early standard specifications are not clear, when some residential communities in some cities are developed and designed, a waste water pipeline is not arranged on a balcony, and only a rainwater pipeline is arranged.

The technical scheme of the utility model is further specifically described below through examples and with reference to the accompanying drawings.
Example 1
Under the conditions of rainy days and no drainage of washing wastewater from a balcony, only rainwater is received in the rainwater vertical pipe 1, and the first flow sensor 27 on the drainage transverse pipe 28 does not have action reaction. In this case, roof rainwater will get into rainwater riser 1 through rainwater funnel 26, later get into in initial rainwater and the washing waste water collection unit jar body 6, when rainfall time after, when initial rainwater and washing waste water collection unit jar body 6 in initial rainwater reach certain liquid level, first liquid level sensor 3 can send the signal to rotary actuator 2-1 and first centrifugal pump 9, rotary actuator 2-1 can drive transmission pivot 2-2 and open water proof cover 2-3, water proof cover 2-3 is opened back in the later stage rainwater can get into the river course through middle-stage rainwater discharge tube 4. The initial rainwater enters the purification treatment unit to be purified under the drive of the first centrifugal pump 9, enters the mixing drum 12 after the coagulant PAM is added, and is mixed with the initial rainwater through stirring to form flocculating particles. The water with the flocculated particles enters the purifying device tank 19 through the guide cylinder 18, after aeration treatment, enters the anthracite filter bin 20-1, the quartz sand filter bin 20-2 and the active carbon filter bin 20-3 in sequence under the suction action of the second centrifugal pump 23, and under the action of each filter bin, suspended particles and organic matters in the water to be treated are trapped and adsorbed, so that the negative influence of initial rainwater on the water environment is slowed down, and the purified rainwater can supplement the water quantity of the water body to a certain extent.
Example 2
In the rainless weather condition, the old community users may drain the washing wastewater by using the rainwater vertical pipe 1, and only the washing wastewater is received in the rainwater vertical pipe 1. In this case, the laundry wastewater enters the rainwater riser 1 through the horizontal drainage pipe 28, the first flow sensor 27 provided on the horizontal drainage pipe 28 sends a signal to the rotary driver 2-1, and the water-stop cover 2-3 in the initial rainwater and laundry wastewater collecting unit is always in a closed state, so that the laundry wastewater in the rainwater riser 1, the initial rainwater and the laundry wastewater in the laundry wastewater collecting tank 6 cannot enter the river channel through the middle-late rainwater discharge pipe 4 to pollute the environment. When the liquid level in the initial rainwater and washing wastewater collection tank 6 reaches a certain height, the first liquid level sensor 5 sends a signal to the first centrifugal pump 9, and at the moment, the first centrifugal pump 9 is started to suck the water to be treated in the tank and convey the water to the initial rainwater and washing wastewater purification treatment unit. The water to be treated enters the mixing drum 12 after adding the coagulant, and the medicament and the water to be treated are fully mixed through stirring action to form flocculation particles. The water with the flocculated particles enters the purifying device tank 19 through the guide cylinder 18, after aeration treatment, enters the anthracite filter bin 20-1, the quartz sand filter bin 20-2 and the activated carbon filter bin 20-3 in sequence under the suction action of the second centrifugal pump 23, and under the action of each filter bin, suspended particles and organic matters in water to be treated are intercepted and adsorbed, so that the problem that the washing wastewater is directly discharged into a river channel to pollute the environment is avoided, the water environment eutrophication condition is effectively improved, and the purified water can also supplement the water quantity of the water body to a certain extent.
Example 3
In the case of a rainy day situation and a balcony where laundry wastewater is discharged, there is a possibility that rainwater may be received in the rain pipe 1 at this time, and laundry wastewater may also be received. In this case, roof rainwater enters the rainwater stand pipe 1 through the rainwater hopper 28, and then enters the initial rainwater and laundry wastewater collection tank 6 in the initial rainwater and laundry wastewater collection unit. When rainfall is over a period of time, if the water level in the tank body reaches a certain height, the water stop cover plate 2-3 can be driven to be opened, and the middle-late stage rainwater can enter the river along with the middle-late stage rainwater discharge pipe 4. If the situation that the user discharges the washing wastewater in the home occurs in the rainfall process, the first flow sensor 27 on the horizontal drainage pipe 28 sends a signal to the rotary driver 2-1 to drive the transmission rotating shaft 2-2 to close the water-stop cover plate 2-3, so that the washing wastewater is prevented from flowing into the middle-later stage rainwater drainage pipe 4 to enter the river. At this time, the initial rainwater and the washing wastewater in the washing wastewater collecting tank 6 receive part of the rainwater and the washing wastewater, and when the initial rainwater and the washing wastewater reach a certain liquid level, the first liquid level sensor 3 sends a signal to the first centrifugal pump 9. The initial rainwater and the washing wastewater enter a purification treatment unit to be purified under the drive of a pump, water to be treated enters a mixing drum 12 after being added with a coagulant, and the agent and the initial rainwater are fully mixed through stirring to form flocculating particles. The water with the flocculated particles flows into the purifying device tank 19 through the guide cylinder 18, after aeration treatment, the water sequentially enters the anthracite filtering bin 20-1, the quartz sand filtering bin 20-2 and the activated carbon filtering bin 20-3 under the suction action of the second centrifugal pump 23, and under the action of each filtering bin, suspended particles and organic matters in the water to be treated are trapped and adsorbed, so that the negative influence of initial rainwater and washing wastewater on the water environment is relieved, and the purified water can supplement the water quantity of the water body to a certain extent.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
