Description

Technical Field

[0001] The present disclosure relates to the technical field of wastewater treatment, and in particular to an emergency collection device for wastewater treatment. Background Art

[0002] During the implementation of pilot projects in the semiconductor or photovoltaic research industry, wastewater and waste liquid will be generated, but the wastewater and waste liquid generated in this process are generally small, and only a small collection and treatment system is required. However, the collection and treatment system has a soaking tank process before starting up, which requires a large amount of water. In addition, during the pilot process, the potion in the tank will also need to be replaced after a long operation time due to increasing pollutants. When the traditional treatment equipment is running, the design water will stay in the collection barrel of the system for about half a day to a day, but because the amount of water in the soaking tank and tank replacement process is relatively large, it generally reaches 2-3 times the average water volume, and the collection barrel capacity in the system is small, resulting in the soaking tank water or tank replacement water cannot be discharged at one time, and can only be discharged while being treated. However, the materials put into the soaking tank are alkaline materials first and then acidic materials, and the concentration reaches 2-5%. If it is directly treated, it will not only waste a long time, but also waste a lot of acid and alkali materials for dilution.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0033] The term "and / or" herein is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0034] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0035] It can be understood that the above-mentioned various method embodiments mentioned in the present disclosure can be combined with each other to form a combined embodiment without violating the principle logic. Due to space limitations, the present disclosure will not go into details.

[0036] During the manufacturing process of semiconductor and photovoltaic products, wastewater and waste liquids include heavy metal waste liquid, heavy metal wastewater, organic wastewater and organic waste liquid, and the concentration and water quality types of the above wastewater and waste liquids are all different. Traditional collection barrels directly recycle the above-mentioned different types of wastewater and waste liquids, and do not distinguish between the above-mentioned wastewater and waste liquids, resulting in a large amount of waste of neutralization materials. Some wastewater collection devices are equipped with collection barrels for different types of wastewater and waste liquids, which will waste equipment costs, because the output of some wastewater and waste liquids in the production process is relatively small, and it is not convenient to set up collection barrels separately. In addition, traditional collection barrels can only maintain the normal operation of the wastewater treatment system. Once other wastewater treatments are carried out, they will not be able to meet the needs of collecting wastewater and waste liquids.

[0037] In order to solve the above problems, the present invention provides a wastewater treatment emergency collection device, such as Figure 1As shown, a variety of different types of wastewater and waste liquid can be treated at the same time, and resources and equipment costs can be saved, including: a water outlet, a common valve group, a one-way valve group, an electric valve group, an emergency treatment part, a collection part and a connecting line. The water outlet leads out different types of wastewater and waste liquid, and the connecting lines correspond to different types of wastewater and waste liquid settings, and lead different types of wastewater and waste liquid to subsequent structures. In order to meet the needs of separate treatment of different types of wastewater and waste liquid, adding neutralizing materials, and meeting the water capacity requirements during the wastewater treatment process, a common valve group, a one-way valve group, an electric valve group, an emergency treatment part, a collection part and other structures are set for treatment. Specifically, the emergency treatment unit includes a heavy metal wastewater treatment unit and an organic wastewater treatment unit, and different neutralizing materials are respectively added to the heavy metal wastewater treatment unit and the organic wastewater treatment unit; the collection unit includes a heavy metal waste liquid collection unit, a heavy metal wastewater collection unit, an organic wastewater collection unit, and an organic waste liquid collection unit; the water outlet unit includes a heavy metal waste liquid outlet unit, a heavy metal wastewater outlet unit, an organic wastewater outlet unit, and an organic waste liquid outlet unit. The electric valve group is arranged between the outlet unit and the collection unit, the electric valve group is also arranged between the collection unit and the emergency treatment unit, the one-way valve group is arranged between the outlet unit and the emergency treatment unit, the ordinary valve group includes a plurality of valves, and the plurality of valves are arranged at preset positions of the connecting line; the connecting line runs through the ordinary valve group, the one-way valve group, and the electric valve group, and the connecting line connects the emergency treatment unit and the collection unit. Among them, the one-way valve group and the ordinary valve group are both designed to meet the needs of manual operation and manual control of the staff, to avoid emergencies during the automatic processing process, and to avoid damage to the equipment. The emergency treatment section is used to receive wastewater and waste liquid during the operation of the system, and to ensure that there is sufficient accommodation space when the corresponding collection section can no longer receive them.

[0038] In the embodiments of the present disclosure, Figure 1As shown, the solenoid valve group is arranged between the outlet and the collection part and between the outlet and the emergency treatment part, the purpose is to realize the automatic operation in the device, that is, when the various types of waste water and waste liquid output by the outlet are about to exceed the capacity of the collection part, they can enter the emergency treatment part through the connecting line, that is, other solenoid valves. Specifically, the solenoid valve group includes the first group and the second group; the first group and the second group are respectively arranged on the connecting line; the first group includes solenoid valve A, solenoid valve B, solenoid valve C and solenoid valve D, and the solenoid valves of the first group are respectively arranged corresponding to the heavy metal waste liquid outlet, the heavy metal waste water outlet, the organic waste water outlet and the organic waste liquid outlet, so as to ensure the accuracy of the automatic discharge of these waste water and waste liquids, reduce the waste of resources and the work intensity of the staff. The heavy metal waste liquid collection part, heavy metal waste water collection part, organic waste water collection part and organic waste liquid collection part in the collection part and the heavy metal waste liquid outlet part, heavy metal waste water outlet part, organic waste water outlet part and organic waste liquid outlet part in the outlet part are respectively set in one-to-one correspondence through electromagnetic valve A, electromagnetic valve B, electromagnetic valve C and electromagnetic valve D, so as to ensure that all kinds of waste water and waste liquid can be collected efficiently and automatically. A second group including electromagnetic valve a, electromagnetic valve b, electromagnetic valve c and electromagnetic valve d is also set. The purpose of setting the second group of electromagnetic valves is to solve the problem that when the discharge volume of waste water and waste liquid is large and the collection part can no longer accommodate it when the whole device is working normally, the corresponding second group of electromagnetic valves can be automatically opened for collection. The problem of excessive flow of waste liquid and waste water and insufficient outlet space in the processing process is solved.

[0039] In this embodiment, if Figure 1 As shown, ordinary valve groups are also set at the downstream of the first group of solenoid valves A, B, C and D, and the downstream of the ordinary valve groups are respectively connected to the heavy metal waste liquid collection part, the heavy metal waste water collection part, the organic waste water collection part and the organic waste liquid collection part. In the actual application process, in order to avoid unexpected situations in the process of automatically collecting waste water and waste liquid, ordinary valve groups are set at the rear end of each solenoid valve position for manual emergency treatment operations, which increases the safety of the entire device and facilitates management by staff.

[0040] In the embodiments of the present disclosure, Figure 1As shown, considering the need to directly collect wastewater and waste liquid into the emergency treatment unit when the output of wastewater and waste liquid is large, a one-way valve group is also provided between the water outlet and the emergency treatment unit, and the water outlet is connected to the one-way valve group through a common valve group. The one-way valve group includes a number of one-way valves, and the one-way valves correspond to different water outlets. The one-way valve, as a valve for one-way guide of wastewater and waste liquid, can further improve the conduction speed of wastewater and waste liquid. In order to facilitate the control of the staff, a common valve group is provided on the front side of each one-way valve group, which is convenient for the staff to manually control. Specifically, the heavy metal waste liquid outlet and the heavy metal waste water outlet are connected to the heavy metal waste water treatment unit and the organic waste water treatment unit through a one-way valve group respectively; the organic waste water outlet and the organic waste liquid outlet are connected to the heavy metal waste water treatment unit and the organic waste water treatment unit through a one-way valve group respectively.

[0041] In actual application, when it is necessary to perform maintenance operations on the equipment, it is usually necessary to place the wastewater and waste liquid directly in the emergency treatment department to perform maintenance operations on other parts of the device. When performing maintenance operations, the maintenance cycle is usually 1-3 months, and the maintenance cycle of some equipment is 1 year. The water quality of maintenance water is generally not too bad, but the amount of maintenance water will be relatively large, which makes it impossible for the conventional collection department to accommodate it. Therefore, the water needs to be sent directly to the emergency treatment department for temporary collection operations. In this process, according to the type of water sample, the maintenance water can be manually selected to enter the organic or heavy metal wastewater barrel for treatment. Generally, all emergency water can be processed in one to two weeks without affecting the next use. This not only achieves the purpose of classified collection and treatment, but also expands the emergency capacity of the device.

[0042] In the embodiments of the present disclosure, Figure 1As shown, a second group is arranged between the one-way valve group and the emergency treatment part, and the second group of solenoid valves are arranged in the one-way valve and the emergency treatment part, and are used to coordinate the automatic treatment valves in the device to treat wastewater and waste liquid and expand the volume space. Specifically, after the one-way valve groups corresponding to the heavy metal waste liquid outlet and the heavy metal waste water outlet are connected to the heavy metal waste water treatment part through solenoid valve a, and to the organic waste water treatment part through solenoid valve d; after the one-way valve groups corresponding to the organic waste water outlet and the organic waste liquid outlet are connected to the organic waste water treatment part through solenoid valve c, and to the heavy metal waste water treatment part through solenoid valve b. Among them, the difference between heavy metal waste liquid and heavy metal waste water is that the water quality type is the same but the concentration is different. The heavy metal ion concentration of waste liquid is much higher than that of waste water, which may be 100-1000 times that of waste water. Similarly, the organic matter concentration of organic waste liquid is 100-1000 times that of organic waste water. When performing maintenance operations or other treatment operations, the maintenance water is acid and alkali maintenance water respectively. For example, first use alkaline water, put 5% sodium hydroxide in the emergency treatment part, and then add appropriate amount of sulfuric acid to neutralize the alkalinity in the emergency treatment part. This way, there is no need to waste acid and alkali materials, thus reducing material waste.

[0043] In this embodiment, ordinary valve groups are respectively arranged downstream of the solenoid valve a, the solenoid valve d, the solenoid valve b and the solenoid valve c. The ordinary valves are also used to optimize the manual control operation of the staff and improve the convenience of device management.

[0044] A heavy metal wastewater treatment unit is also provided, which is connected to the upstream of the solenoid valve B through a common valve group, and an organic wastewater treatment unit is connected to the upstream of the solenoid valve C through a common valve group. Since the concentration of the waste liquid is higher than that of the waste water, the waste water and waste liquid in the emergency treatment unit do not need to be returned to the heavy metal waste liquid collection unit and the organic waste liquid collection unit, thereby avoiding repeated treatment of the treated liquid and saving resources and treatment time.

[0045] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
