Description

Public Building Wastewater Reuse System

technical field

The utility model relates to a waste water reuse system, in particular to a public building waste water reuse system.

Background technique

Water is the source of people's life, the water resources on the earth are limited, and our country is a country that is seriously short of water. In today's increasingly tense water resources, a lot of reusable water in our lives is wasted, especially in some public buildings such as student dormitory buildings, waiting rooms, etc., the waste water used in public washrooms on each floor It is directly discharged, but the flushing water used in the bathroom and urinal is clean tap water, which not only increases the discharge of waste water, but also causes a waste of water resources.

Utility model content

The purpose of the utility model is to provide a public building waste water reuse system.

In order to achieve the above object, the utility model can take the following technical solutions:

The public building wastewater reuse system described in the utility model includes a filter water tank arranged in a public wash room on each floor and a water storage tank provided with a water level detector, the filter water tank communicates with the water outlet of the wash room pool, The water outlet of the filtered water tank is connected to the water storage tank in the wash room on the lower floor through the pipeline; the water storage tank on each floor is connected to the flushing pipe of the toilet and urinal on the floor through the pipeline and the automatic control valve; the water storage tank is equipped with an automatic control valve The replenishment pipe of the water tank is connected with the running water pipe; the overflow port of the water storage tank is connected with the urinal or the urinal flushing pipe through the pipe; the filtered water tank in the public washroom on the ground floor is connected to the water storage tank in the public washroom on the top floor through a water pump and a water pipe connected.

The water storage tank on each floor communicates with the running water pipeline through a bypass pipe provided with a manual valve.

The automatic control valve is a manual and electric dual-purpose valve.

Infrared counting sensors are installed at the urinals and urinals of the bathrooms on each floor.

The water storage tank has a cylindrical structure, and an inner wall cleaner is arranged in it.

The utility model has the advantages of making full use of water resources, and transporting the waste water from the washing room of the public building to the water storage tank on the lower floor after being filtered by the filter water tank for flushing in the toilet and urinal; The control valve and the infrared counting sensor installed at the urinal and urinal in the bathroom can be automatically controlled by a programmable controller, such as setting the number of flushes according to the number of urinals and urinals; when the water storage tank is low or dry, It can also collect signals through the water level detector installed on it to open the automatic valve of the water replenishment pipe for the programmable controller to replenish water to the water storage tank; when the power fails, the manual valve arranged on the bypass pipe can replenish water to the water storage tank. The water storage tank is set as a cylindrical structure, and the water storage tank can be cleaned and decontaminated regularly by the motor-driven brush cleaner arranged therein.

Fig. 1 is the waste water reuse system diagram that is arranged in the public washing room of each floor according to the utility model.

Fig. 2 is the communication system diagram of the filter water tank in the public wash room on the ground floor and the water storage tank in the public wash room on the top floor described in the utility model.

Detailed ways

As shown in the figure, the public building wastewater reuse system described in the utility model includes a filtered water tank 1 arranged in a public wash room on each floor and a water storage tank 3 provided with a water level detector 2, and the filtered water tank 1 and The water outlet of the wash room pool is connected, and the water outlet of the filtered water tank 1 is connected with the water storage tank 3 in the wash room of the lower floor through the pipeline; The pool flushing pipes 5 and 6 are connected; the water storage tank 3 is connected with the running water pipe through the replenishment pipe 7 provided with an automatic control valve; the overflow of the water storage tank 3 is connected with the flushing pipe of the urinal 9 through the pipe 8; The filtered water tank 1 communicates with the water storage tank 3 in the public wash room on the top floor by a water pump 11 and a water delivery pipe 12. In order to make the power failure replenish water to the water storage tank 3, the water storage tank 3 on each floor communicates with the tap water pipeline through a bypass pipe 14 provided with a manual valve 13, and the automatic control valve 4 is selected as a manual and electric dual-purpose valve. Infrared ray counting sensors 15 are respectively arranged at the big and urinal 9,10 positions of the bathroom on each floor, and the automatic control of flushing times is set according to the number of people who urinate and urinate through a programmable controller. The water storage tank 3 is configured as a cylindrical structure, and an inner wall cleaner 16 is arranged therein for cleaning and descaling on a regular basis.
