[0002] Wastewater is often generated during industrial production, and it is necessary to recycle or discharge the wastewater generated during industrial production. Automatic water quality analyzers can monitor various pollutants in sewage, such as suspended solids, chemical oxygen demand, ammonia nitrogen, total phosphorus, etc., to help optimize sewage treatment and ensure that sewage discharge meets standards. The components contained in sewage samples are complex, and most of the polluting components are low in content and exist in various forms. Therefore, before analysis and determination, sample pretreatment corresponding to the analytical method is required to obtain the sample system that meets the form and concentration requirements of the measurement method and eliminates the interference of coexisting components. However, since sewage samples contain a large amount of particulate matter such as sediment, they have a high interference with detection; in addition, since sewage samples also contain oily components, they are easy to adhere to the detection equipment during the detection process, thereby causing the substances to be monitored in the sewage samples to be lost, affecting the accuracy of the test data.

[0043] Embodiment 1

[0044] Figure 1 The following is a schematic diagram of a process for pre-treating industrial wastewater samples provided in an embodiment of the present disclosure. Figure 1 As shown, a method for pretreating industrial wastewater samples comprises:

[0045] Step 01: Input the sewage sample into the sedimentation tank and obtain the suspended solid particle data and oil concentration in the water of the sewage sample. Input the sewage sample into the sedimentation tank, which is used to sediment the sewage sample. The sedimentation monitoring sensor is set in the sedimentation tank. During the sedimentation process of the sewage sample, the sedimentation monitoring sensor monitors the suspended solid particle data and oil concentration in the sewage sample, and then transmits the monitored data to the control system.

[0046] Step 02: Set stirring parameters and settling time according to the suspended solid particle data, and stir according to the stirring parameters during the settling process.

[0047] The control system receives the suspended solid particle data and oil concentration in the water transmitted by the sedimentation monitoring sensor, and controls the stirring parameters and sedimentation time in the sedimentation tank according to the preset control program to ensure that the suspended matter, silt and other solid particles in the sedimentation tank are fully settled in the most appropriate time period, thereby achieving the initial separation and purification of sewage.

[0048] Step 03: After reaching the settling time, extract the water sample in the settling tank and transport it to the emulsification tank.

[0049] According to different water sample conditions and required sample requirements, after the sedimentation time is reached, the control system controls the opening and closing of the sedimentation tank discharge valve according to the preset control program, extracts part of the water sample from the top or middle of the sewage sample that has completed sedimentation, and transports it to the emulsification tank.

[0050] The control system controls the power equipment to extract water samples from the top or middle of the sedimentation tank and transport them to the emulsification tank. During the water sample transportation process, the liquid only contacts the pump tube, which can effectively avoid contamination during the water sample collection process and prevent corrosion and damage to the pump caused by corrosive water samples.

[0051] Step 04: Adjust the emulsification parameters according to the oil concentration parameters in water, and perform emulsification.

[0052] After the water sample is transported to the emulsification tank, the control system adjusts the ultrasonic emulsification parameters according to the requirements of the water sample, including frequency, time, power, etc. Ultrasonic waves are used to treat water samples containing oil. Under the action of ultrasonic energy, the oil droplets are broken up, and the immiscible liquids in the sewage water sample are mixed together to form an emulsion-like liquid. The emulsification device breaks up the oil contained in the sewage into particles, so that the treated samples are more uniform, reducing the adhesion and blockage of oil in the analysis system pipeline.

[0053] Step 05: During the emulsification process, obtain the particle size distribution of the oil molecules in real time to obtain the emulsification degree.

[0054] Step 06: Determine whether emulsification is completed based on the emulsification degree. Determine whether the particle size distribution of the obtained oil molecules reaches the preset particle size distribution, and if so, stop emulsification.

[0055] After the emulsification is completed, step 07 is also included: analyzing the emulsified water sample to determine whether it meets the discharge standard. After the emulsification stops, the emulsified water sample is transported to the analysis equipment for analysis to analyze whether the suspended solids, chemical oxygen demand, ammonia nitrogen, total phosphorus and other components in the sewage meet the discharge standard. If so, it is determined that the sewage can be discharged directly; if not, it is determined that the sewage needs to be optimized before discharge.

[0056] The method provided in this embodiment designs the process of pretreatment of industrial wastewater samples to ensure the effectiveness and accuracy of analytical data, optimize the detection concentration range of the components to be tested, increase the operation and maintenance cycle, and help optimize wastewater treatment and ensure that wastewater discharge meets standards.

[0057] Embodiment 2

[0058] On the basis of the above embodiment, after the water sample in the extraction sedimentation tank is transported to the emulsification tank, the method also includes: cleaning the sedimentation tank; the cleaning of the sedimentation tank includes: pumping air into the sedimentation tank, and adding cleaning water and cleaning liquid at the same time; stirring the sedimentation tank, and discharging the sewage sample and cleaning agent after a preset time; continuing to pump air to blow the sedimentation tank dry.

[0059] After each sample collection, the sedimentation tank needs to be cleaned and discharged before the next pretreatment process. As time goes by, the suspended matter and sediment in the tank will increase. In order not to affect the treatment effect, the control system controls the air compressor to pump air into the sedimentation tank, and at the same time, add cleaning water and cleaning liquid into the sedimentation tank respectively, and stir and clean it with a stirring rod. After cleaning, the water sample and cleaning agent are discharged, and then air is continued to be pumped into the sedimentation tank to dry the sedimentation tank.

[0060] Softened water or desalted water can be used for equipment cleaning. After each pipeline sampling or analysis, the pipeline or analysis module should be flushed 2 to 3 times with cleaning water and then blown dry with air. The equipment is set to use cleaning fluid for cleaning at a fixed period to remove residual particulate matter in the sedimentation tank.

[0061] Embodiment 3

[0062] On the basis of the above embodiment, after the emulsification is completed, the emulsification tank is cleaned; the method for cleaning the emulsification tank also includes: pumping air into the emulsification tank, and adding cleaning water and cleaning liquid respectively; ultrasonically cleaning the emulsification tank, discharging the sewage sample and cleaning agent after a preset time; and continuing to pump air to dry the emulsification tank.

[0063] After each sample collection, the emulsification tank needs to be cleaned and discharged before the next pretreatment process. When the water sample is emulsified, the air pump operates to pump air into the sedimentation tank, and at the same time, cleaning water and cleaning liquid are added to clean the emulsification tank. The emulsification tank can be cleaned under ultrasonic vibration. After cleaning, the emulsified water sample and cleaning agent are discharged, and then air is continued to be pumped into the sedimentation tank to dry the emulsification tank.

[0064] Softened water or desalted water can be used for equipment cleaning. After each pipeline sampling or analysis, the pipeline or analysis module should be flushed 2 to 3 times with cleaning water and then blown dry with air. The equipment should be cleaned with cleaning fluid at a fixed period to remove components such as oil attached to the emulsification tank, pipeline and analysis equipment.

[0067] Furthermore, the analysis equipment is also used to analyze the emulsified water sample after the emulsification is completed to determine whether the discharge standards are met.

[0068] In addition to the above structure, the industrial wastewater sample pretreatment device also includes an air compressor and a storage device. The air compressor is connected to the sedimentation tank and the emulsification tank through an air pipeline and is used to pump air into the sedimentation tank and the emulsification tank; the storage device is connected to the sedimentation tank and the emulsification tank through a liquid pipeline and is used to input the stored cleaning water and cleaning liquid into the sedimentation tank and the emulsification tank through the liquid pipeline.

[0074] Embodiment five:

[0075] Based on the above embodiment, the emulsified water sample is analyzed to determine whether it meets the discharge standard. If it does not meet the discharge standard, it is determined that the sewage needs to be optimized and then recycled or discharged. Currently, the sewage pretreatment technologies mainly include coagulation and sedimentation.

[0076] Coagulation is composed of two processes: coagulation and flocculation. Coagulation mainly refers to the process of destabilization of colloids after the double electrical layer is compressed; flocculation mainly refers to the process of colloids condensing into large flocs after destabilization. Coagulation is mainly used to remove suspended matter, colloidal substances and some soluble substances in water, and reduce the turbidity, color and part of the chemical oxygen demand of water.

[0077] Sedimentation method uses the natural sedimentation method. There are many suspended solids in sewage that are denser than water, so they can sink naturally. Using this principle to separate solids and liquids in sewage is called sedimentation method. Sedimentation devices for sewage treatment are generally divided into two categories: one is mainly used to settle inorganic solids, called sand settling tanks; the other is mainly used to settle organic solids, called sedimentation tanks. Sedimentation method is mainly used to remove sediment and suspended matter produced after coagulation to further improve water quality.
