Kitchen waste water treatment device

Abstract

This invention discloses a kitchen waste water treatment device, comprising a reaction tank, a first pump, an ozone supply module, a collector, a first filtration unit, a second filtration unit, a water quality analyzer, and an automation control unit. The ozone supply module draws kitchen waste water from the reaction tank and mixes it with ozone, converting the kitchen waste water into a first treated water which is then returned to the reaction tank. When the automation control unit determines, via the water quality analyzer, that a first water quality data point of the first treated water is below a first threshold, it discharges the first treated water to the second filtration unit for filtration to convert it into second treated water. When the automation control unit determines, via the water quality analyzer, that a second water quality data point of the second treated water is below a second threshold, it issues a discharge notification to discharge the second treated water.

Claims

1. A kitchen waste water treatment device, comprising: a reaction tank; a first pump connected to the reaction tank, the first pump being capable of drawing kitchen waste water to a predetermined liquid level in the reaction tank; an ozone supply module connected to the reaction tank, the ozone supply module being capable of drawing kitchen waste water from the reaction tank to mix with ozone, thereby converting the kitchen waste water into a first treated water and flowing into the reaction tank; a collector connected to the reaction tank, the collector being positioned below the predetermined liquid level, and the collector being capable of collecting the first treated water overflowing from the reaction tank; a first filtration unit connected to the collector, the first filtration unit being capable of receiving and filtering the first treated water from the collector before flowing into the reaction tank; and a second filtration unit connected to the reaction tank, the second filtration unit being capable of receiving the first treated water from the reaction tank and filtering the first treated water to convert it into a second treated water. A water quality tester is connected to the reaction tank and the second filtration unit, and the water quality tester can test the first treated water in the reaction tank and the second treated water in the second filtration unit; and an automation control unit is electrically connected to the first pump, the ozone supply module, and the water quality tester; wherein... When the automated control unit determines, through the water quality tester, that a first water quality data of the first treated water is lower than a first threshold, it can discharge the first treated water to the second filtration unit for filtration to convert it into the second treated water; when the automated control unit determines, through the water quality tester, that a second water quality data of the second treated water is lower than a second threshold, it issues a drainage notification to discharge the second treated water.

2. The kitchen waste water treatment device as described in claim 1, wherein, When the automated control unit determines, through the water quality tester, that the first water quality data of the first treated water is higher than a first threshold, the first treated water is returned to the reaction tank and, after a first waiting time, is tested again by the water quality tester; when the automated control unit determines, through the water quality tester, that the second water quality data of the second treated water is higher than the second threshold, the second treated water is transported to the reaction tank and, after a second waiting time, is tested again by the water quality tester.

3. The kitchen waste water treatment device as described in claim 1, wherein, The food waste water treatment device also includes an anomaly sensing unit disposed on the reaction tank. The anomaly sensing unit includes a water pressure sensor and a controller. When the food waste water treatment device stops or restarts due to a sudden situation, the water pressure sensor can detect the water pressure in the food waste water treatment device and continuously transmit the water pressure value to the controller. When the water pressure value received by the controller is lower than a third threshold, the controller will issue a water replenishment notification to the automation control unit to perform a water replenishment operation. When the water pressure value received by the controller is higher than or equal to the third threshold, it will issue a stop notification to the automation control unit to stop the water replenishment operation.

4. The kitchen waste water treatment device as described in claim 1, wherein, The kitchen waste water treatment device further includes a water storage tank connected to the reaction tank, the water storage tank being used to store a replenishing liquid, and the replenishing liquid being able to be transported to the reaction tank to dilute the kitchen waste water, or to maintain the liquid in the reaction tank at at least one of the predetermined liquid level positions; wherein the replenishing liquid is a water source from the external environment, or at least one of the second treated water.

5. The kitchen waste water treatment device as described in claim 4, wherein, The kitchen waste water treatment device further includes a liquid level sensor disposed in the reaction tank. The liquid level sensor can detect the liquid level in the reaction tank and control the replenishment liquid in the storage tank to be delivered to the reaction tank. Specifically, when the liquid level sensor detects that the liquid level of the kitchen waste water in the reaction tank is lower than the predetermined liquid level, a water replenishment action is initiated to deliver the replenishment liquid to the reaction tank. When the liquid level sensor detects that the liquid level of the kitchen waste water in the reaction tank is higher than the predetermined liquid level, the liquid level sensor controls the water replenishment action to stop.

6. The kitchen waste water treatment device as described in claim 1, wherein, The ozone supply module further includes an ozone supplier, a second pump connected to the ozone supplier, and a plurality of gas-liquid mixing elements connected to the second pump; wherein the second pump can draw the kitchen waste water from the reaction tank, and each of the gas-liquid mixing elements can mix the ozone into the kitchen waste water in the form of micro-nano bubbles through the second pump.

7. The kitchen waste water treatment device as described in claim 4, wherein, The kitchen waste water treatment device also includes a diversion unit disposed in the reaction tank. The diversion unit can draw the replenishment liquid in the water storage tank and discharge water towards the first treated water located in the reaction tank, so that the liquid surface of the first treated water is diverted to the collector.

8. The kitchen waste water treatment device as claimed in claim 1, wherein, The gas-liquid mixing ratio of the kitchen waste water and the ozone is 7:3 to 8:

2.

9. The kitchen waste water treatment device as described in claim 1, wherein, The first filtration unit includes at least one of a bag filter and a filter belt.

10. The kitchen waste water treatment apparatus as claimed in claim 1, wherein, The second filtration unit includes at least one of a sand filter, an activated carbon filter, an ion exchanger, a reverse osmosis filter, an ultraviolet sterilizer, or a filter belt.
