Description

Technical Field

[0001] The invention relates to the technical field of zero wastewater discharge, in particular to a zero wastewater discharge device. Background Art

[0002] The desalted water preparation of the power plant mainly adopts the full membrane water production technology, which is an efficient water treatment process that integrates multiple membrane separation technologies. Specifically, this process includes three key steps: ultrafiltration (UF), reverse osmosis (RO) and electrodeionization (EDI), each of which targets different water quality requirements and pollutant removal goals. Ultrafiltration, as a pretreatment step, can effectively remove suspended matter, colloids and macromolecular organic matter in the water, providing a clean water source for the subsequent reverse osmosis process. Reverse osmosis technology removes dissolved salts, organic matter and microorganisms in the water under pressure through a semi-permeable membrane, and the water quality of the produced water is close to the pure water standard. Finally, EDI technology further removes ions through the action of an electric field to achieve the preparation of high-purity water.

[0003] Although this technology can produce high-purity demineralized water, a large amount of flushing water with good water quality will be produced during the equipment backwashing process, accounting for about 50% of the entire process. This water is directly discharged into the chemical return water tank, resulting in a waste of water resources. In addition, as the gas turbine is gradually adjusted to the peak operation mode, the waste heat boiler discharge volume during the start-up and shutdown stages of the unit has increased significantly, resulting in the original boiler blowdown tank being unable to bear the load.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a wastewater zero discharge device that can effectively treat wastewater from power plants and enhance the efficiency of wastewater treatment in the return water tank 102.

[0027] Specifically, it includes a processing component 100, including a water inlet pipe 101, a return water tank 102 connected to one side of the water inlet pipe 101, a first pipe 103 connected to one side of the return water tank 102, a first gate valve 104 arranged on the outer wall of the first pipe 103, a first water pump 105 connected to one side of the first pipe 103 and a first diverter pipe 109 connected to one side of the first water pump 105, a third gate valve 110 is arranged on the outer wall of the first diverter pipe 109, and one side of the second water pump 108 is connected to one side of the first diverter pipe 109;

[0028] It should be noted that in order to better explain how the overall device operates, the water levels of the wastewater are referred to as A value and B value, where A value is less than B value;

[0029] Among them, the wastewater will enter the return water tank 102 from the water inlet pipe 101. When the wastewater water level in the return water tank 102 reaches the A value, the first gate valve 104 will be opened, so that the first water pump 105 will pump the treated wastewater into the first pipe 103, where the wastewater will flow through the first pipe 103 to the first diversion pipe 109, and the third gate valve 110 on the first diversion pipe 109 will open to allow the water to flow to other pipes.

[0030] The discharge assembly 200 is arranged at one side of the first shunt pipe 109, and includes a first detection unit 201, a first delivery pipe 202 connected to one side of the detection unit 201, a second shunt pipe 203 connected to one side of the first delivery pipe 202, a second delivery pipe 204 connected to one side of the second shunt pipe 203, a reverse osmosis device 209 connected to one side of the second delivery pipe 204, a second detection unit 210 connected to one side of the reverse osmosis device 209, and a discharge pipe 211 connected to one side of the second detection unit 210, one side of the first detection unit 201 is connected to one side of the first shunt pipe 109, one side of the discharge pipe 211 is provided with a drain port 213, one side of the second shunt pipe 203 is connected to a fourth delivery pipe 214, an outer wall of the fourth delivery pipe 214 is provided with a seventh gate valve 215, and one side of the fourth delivery pipe 214 is connected to the outer wall of the discharge pipe 211;

[0031] Among them, the wastewater in the first diversion pipe 109 will pass through the first detection unit 201. At this time, the first detection unit 201 will detect the turbidity and conductivity of the wastewater. When the turbidity and conductivity of the wastewater reach the discharge standard, it means that the wastewater treatment is completed, and the discharged water flow is no longer wastewater. At this time, the seventh gate valve 215 will be opened, and the other gate valves connected to the second diversion pipe 203 will be closed. The water flow will flow through the fourth delivery pipe 214 to the discharge pipe 211, and then be discharged from the drain outlet 213.

[0032] Example 2

[0033] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that this embodiment will explain how the wastewater zero discharge device will operate when the water level reaches the B value, and how the wastewater zero discharge device will operate when the turbidity and conductivity of the wastewater do not meet the discharge standards.

[0034] A second pipe 106 is connected to one side of the return water tank 102, a second gate valve 107 is provided on the outer wall of the second pipe 106, and a second water pump 108 is connected to one side of the second pipe 106. When the water level reaches the B value, the second gate valve 107 will open together with the first gate valve 104, and the second water pump 108 will draw water from the return water tank 102 together with the first water pump 105 to increase the output of wastewater.

[0035] One side of the second diversion pipe 203 is connected to the third delivery pipe 206, and the outer wall of the third delivery pipe 206 is provided with a fifth gate valve 207. One side of the third delivery pipe 206 is connected to a safety filter 208. When the turbidity and conductivity of the wastewater do not meet the discharge standards, the fifth gate valve 207 will open, and the other gate valves connected to the second diversion pipe 203 will be closed. At this time, the wastewater will pass through the safety filter 208 for secondary wastewater treatment.

[0036] One side of the security filter 208 is connected to one side of the reverse osmosis device 209 through a pipeline, and a sixth gate valve 212 is provided on the outer wall of the discharge pipe 211. After the wastewater has been treated by the secondary wastewater of the security filter 208, it will be processed again by the reverse osmosis device 209 so that the wastewater meets the discharge standard. Subsequently, the wastewater will be tested again by the second detection unit 210. When the wastewater meets the discharge standard, the sixth gate valve 212 will be opened to discharge the treated water.

[0037] A fifth delivery pipe 216 is provided on one side of the discharge pipe 211, and an eighth gate valve 217 is provided on the outer wall of the fifth delivery pipe 216. One side of the fifth delivery pipe 216 is connected to one side of the return water tank 102. When the second detection unit 210 detects that the wastewater is unqualified, the sixth gate valve 212 will be closed, and the eighth gate valve 217 will be opened. The wastewater will be discharged into the return water tank 102 again through the fifth delivery pipe 216 for treatment until the wastewater meets the discharge standard.

[0038] Example 3

[0039] Reference Figure 1 to Figure 3 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that this embodiment describes what kind of treatment the wastewater zero discharge device will perform when the conductivity in the wastewater reaches the qualified standard but the turbidity does not reach the qualified standard.

[0040] A fourth gate valve 205 is provided on the outer wall of the second delivery pipe 204, a fifth delivery pipe 216 is provided on one side of the discharge pipe 211, an eighth gate valve 217 is provided on the outer wall of the fifth delivery pipe 216, and one side of the fifth delivery pipe 216 is connected to one side of the return water tank 102. When the first detection unit 201 detects that the conductivity in the wastewater reaches the qualified standard but the turbidity does not reach the qualified standard, the fifth gate valve 207 and the seventh gate valve 215 will be closed, the fourth gate valve 205 will be opened, and the wastewater will be transported from the second delivery pipe 204 to the reverse osmosis device 209 for treatment. Then the second detection unit will detect the wastewater. When the detection is qualified, the sixth gate valve 212 will be opened and the water will be discharged. When the detection is unqualified, the sixth gate valve 212 will be closed, the eighth gate valve 217 will be opened, and the wastewater will be discharged into the return water tank 102 again for treatment.
