There are many things in life that have an impact on the environment and waste resources.

[0003] The existing waste liquid from developing and fixing films has a great impact on the environment, and the fixing solution contains a large amount of metallic silver, which has been included in the "National List of Hazardous Substances". At present, domestic enterprises have a relatively weak ability to recycle waste fixing solution. Although some of them are treated through biological treatment technology and membrane separation technology, these technologies require more R&D efforts and funds, which significantly increases the cost of waste liquid treatment and makes it difficult to meet ordinary treatment needs.

[0031] Embodiment 1: An environmentally friendly film cleaning waste liquid treatment device comprises a waste liquid treatment box 1, a waste liquid filtering component 2 is arranged on the top of the waste liquid treatment box 1, a neutralizing agent adding component 3 is arranged on the side of the waste liquid treatment box 1, a waste liquid detection component 4 is also arranged on the waste liquid treatment box 1, and two waste liquid discharge pipes 5 are symmetrically connected to the side of the bottom end of the waste liquid treatment box 1, and the waste liquid discharge pipes 5 are each provided with a drain valve 6.

[0032] The waste liquid filtering assembly 2 includes a top liquid inlet pipe 201 arranged at the top of the waste liquid treatment box 1, a filter funnel 202 is arranged above the top liquid inlet pipe 201, a bottom liquid outlet 203 is opened at the bottom end of the filter funnel 202, a fixed slot 204 is opened on the bottom liquid outlet 203, a top filter screen plate 205 is inserted in the fixed slot 204, a connecting screw 206 is inserted in the middle of the top filter screen plate 205, a fastening nut 207 is sleeved on the connecting screw 206, a bottom connecting pipe 208 is arranged at the bottom end of the bottom liquid outlet 203, a filter screen cylinder 209 is threadedly inserted on the bottom connecting pipe 208, and three side support plates 210 are evenly arranged on the sides of the filter funnel 202.

[0033] The neutralizer addition component 3 includes a neutralizing liquid storage tank 301 arranged on the top side of the waste liquid treatment tank 1, the bottom end of the neutralizing liquid storage tank 301 is connected to a bottom drainage pipe 302, the bottom end of the bottom drainage pipe 302 is connected to an infusion pipe 303, the end of the infusion pipe 303 is inserted into the waste liquid treatment tank 1, and a flow metering valve 304 is arranged on the bottom drainage pipe 302.

[0034] The waste liquid detection component 4 includes two waste liquid concentration detection sensors 401 symmetrically arranged at the bottom of the waste liquid treatment box 1, a pH value detection sensor 402 is arranged in the middle of the bottom of the waste liquid treatment box 1, and a data display panel 403 is installed on the side of the waste liquid treatment box 1.

[0035] Embodiment 2: The difference between this embodiment and embodiment 1 is that the mesh size of the top filter screen plate 205 is larger than the mesh size of the filter screen cylinder 209 .

[0036] The top filter screen plate 205 can first filter out the large particles of impurities contained in the waste liquid.

[0037] Embodiment 3: The difference between this embodiment and embodiment 1 is that the filter funnel 202 is in the shape of a funnel for easy liquid entry.

[0038] This allows the waste liquid entering the filter funnel 202 to flow downward faster.

[0039] Embodiment 4: The difference between this embodiment and embodiment 1 is that the side of the neutralization liquid storage tank 301 is connected to the waste liquid treatment tank 1 through a fixed block.

[0040] This makes the connection of the neutralizing liquid storage tank 301 to the side of the waste liquid treatment tank 1 more stable.

[0041] Embodiment 5: The difference between this embodiment and embodiment 1 is that an inclined guide plate is provided at the bottom end of the waste liquid treatment box 1 .

[0042] The filtered waste liquid can quickly flow back to one side of the waste liquid treatment box 1 and then be discharged more conveniently through the waste liquid discharge pipe 5.

[0043] Embodiment 6: The difference between this embodiment and embodiment 1 is that, the waste liquid concentration detection sensor 401 and the pH value detection sensor 402 are connected to the data display panel 403 via data lines.

[0044] The data measured by the waste liquid concentration detection sensor 401 and the pH value detection sensor 402 can be transmitted back to the data display panel 403 in a timely manner for presentation.

[0045] In this embodiment, since the existing waste liquid from developing and fixing films has a great impact on the environment, and the fixing solution contains a large amount of metallic silver, which has been included in the "National Hazardous Substances List", domestic companies' current ability to recycle waste fixing solutions is still relatively weak. Although they are also treated through biological treatment technology and membrane separation technology, these technologies require more R&D efforts and funds, which significantly increases the cost of waste liquid treatment and is difficult to meet ordinary treatment needs.

[0046] In summary, in specific implementation, when the user needs to filter the developing and fixing waste liquid in the film washing, the user can first pour the waste liquid into the filter funnel 202, and use the top filter plate 205 set at the bottom of the filter funnel 202 to preliminarily filter the large particles of impurities contained in the waste liquid, thereby greatly reducing the large amount of impurities contained in the waste liquid remaining in the filter cylinder 209.

[0047] The waste liquid filtered by the top filter screen 205 will enter the filter screen cylinder 209 for re-filtration. After the re-filtration by the filter screen cylinder 209, the suspended matter and fine impurities in the waste liquid can be filtered and removed again, so that the waste liquid enters the waste liquid treatment tank 1 after multiple filtrations. At this time, it is necessary to inject appropriate acid-base neutralizing liquid into the neutralizing liquid storage tank 301 in advance. After the filtered waste liquid enters the waste liquid treatment tank 1, the user can open the flow metering valve 304 set on the bottom drain pipe 302, and inject the acid-base neutralizing liquid injected into the neutralizing liquid storage tank 301 into the waste liquid treatment tank 1 through the infusion pipe 303, so as to neutralize and adjust the acidity and alkalinity of the filtered waste liquid.

[0048] A waste liquid concentration detection sensor 401 and a pH value detection sensor 402 are also provided at the bottom of the waste liquid treatment box 1. The waste liquid concentration detection sensor 401 can detect the concentration of pollutants in the waste liquid, and the pH value detection sensor 402 can detect the pH value in the waste liquid, so as to transmit the detection result to the data display panel 403, thereby facilitating the user to control the flow metering valve 304, so as to reasonably add the acid-base neutralizing liquid stored in the neutralizing liquid storage tank 301 to the waste liquid treatment box 1, so as to effectively treat the waste liquid. The device has a simple structure and is easy to operate. It can effectively filter and neutralize the developing and fixing waste liquid in the film washing, thereby greatly reducing the waste liquid treatment cost and meeting the basic needs of ordinary users.
