Description

RO water machine wastewater treatment device

technical field

The utility model relates to a waste water treatment device, in particular to a RO water machine waste water treatment device.

Background technique

The RO water machine is a pure water machine that uses the principle of reverse osmosis technology to filter water. Under a certain pressure, water molecules can pass through the RO membrane, and inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, etc. Impurities cannot pass through the RO membrane, so that part of the water is separated through the RO membrane. The unpermeable water forms concentrated water due to the increase of solute. There are pure water pipes and waste water pipes on the RO water machine. The concentrated water that has not passed through the RO membrane is discharged from the waste pipe into the sewer. Although the waste water contains high content of inorganic salts, bacteria, and colloids, it can be used to wash dishes and vegetables after treatment, and it is directly discharged to cause waste. At present, the concentrated water discharged from the RO water machine cannot be further used and is directly discharged, resulting in waste.

Utility model content

In order to overcome the shortage of waste caused by direct discharge of the concentrated water of the RO water machine in the prior art, the utility model provides a RO water machine wastewater treatment device that can further process and reuse the concentrated water of the RO water machine, thereby reducing waste .

A RO water machine wastewater treatment device, comprising an RO water machine, the RO water machine is provided with a pure water outlet pipe and a waste water pipe, the outer end of the waste water pipe is connected to a water tank, and the lower end of the water tank is provided with a filter plate, the filter plate divides the water tank into a wastewater collection chamber and a water purification chamber, the upper side of the filter plate is also provided with an ultrafiltration membrane, and the bottom of the water purification chamber is connected with a water purification outlet pipe, so The water purification outlet pipe described above is provided with a water pump. The concentrated water flows from the RO water machine into the waste water collection chamber in the water tank and gathers. The concentrated water flows into the water purification chamber after being filtered by the ultrafiltration membrane. When it needs to be used, the water pump is turned on to discharge the clean water in the water purification chamber. Although the clean water is not as clean as the pure water discharged from the RO water machine, the filtered water can be used to wash vegetables, dishes, clothes, etc., so that the concentrated water discharged from the RO water machine can be reused, reducing Small water waste.

Preferably, a controller is provided on the outside of the water tank, a liquid level sensor is provided on the upper side wall of the water tank, the liquid level sensor is connected to the controller, and the controller is provided with an indicator light and a sound Alarm system. When the water quantity in the water tank exceeds the height of the liquid level sensor, the indicator light on the controller will light up, and an audible alarm will be sent simultaneously to remind people to use water.

Preferably, an ultraviolet lamp is provided on the inner wall of the water tank, and a waterproof lampshade is arranged outside the ultraviolet lamp, and the ultraviolet lamp is connected to the controller. The UV lamp can sterilize the water in the tank, thereby reducing the bacteria content in the concentrated water.

Preferably, the water tank is further provided with an overflow pipe, the outer end of the overflow pipe communicates with the sewer inlet, and the upper end of the overflow pipe communicates with the water tank and is higher than the liquid level where the liquid level sensor is located. As the water in the water tank continues to increase, no water is used when the liquid level exceeds the liquid level sensor. Excess water is then drained from the overflow pipe into the sewer.

Preferably, a micro switch is provided on the pure water outlet pipe, the purified water outlet pipe is connected to the micro switch, the micro switch is also connected to the controller, and the water pump is connected to the controller. The micro switch can control the opening of the pure water outlet pipe and the closure of the purified water outlet pipe, and can also control the closure of the pure water outlet pipe and the opening of the purified water outlet pipe. The controller controls the action of the water pump, so that the water in the water purification chamber is discharged from the water purification outlet pipe.

Preferably, a waterproof case is provided on the outside of the controller. Due to the heavy moisture around the water tank, the waterproof cover can prevent water vapor from invading the controller and causing damage to the controller.

As a preference, the included angle between the filter plate and the bottom surface of the water tank is 5°-10°. As the concentrated water is filtered, the impurities in the concentrated water will continue to accumulate on the ultrafiltration membrane. The filter plate is set at an inclination so that the impurities will flow to the lower side along the slope, thereby preventing the impurities from being evenly distributed on the surface of the ultrafiltration membrane. And cause clogging, improve the service life of ultrafiltration membrane.

Therefore, the utility model has the beneficial effect that the concentrated water discharged from the RO water machine can be further processed and reused, thereby reducing waste.
