TECHNICAL FIELD
[0001] The utility model belongs to the technical field of wastewater treatment, specifically relates to a raw material medicine production organic wastewater treatment device. BACKGROUND
[0002] Organic wastewater is generated in the production process of biological medicine raw materials, and such wastewater has the problems of high concentration and difficult degradation. The pollutants in such wastewater are complex in composition, various in type, high in pollution concentration, high in toxicity and high in salt content and difficult to biodegrade. If such organic wastewater is discharged into the environment without treatment, it will inevitably seriously pollute the ecological environment and threaten human health, so it must be properly treated.
[0003] High-concentration wastewater has high CODcr and BOD5 concentrations, and is not suitable for single anaerobic treatment process. Since the organic matter in raw material medicine wastewater contains some toxic and difficult-to-degrade components, single hydrolysis acidification cannot achieve the desired effect. Since high-concentration wastewater has complex composition, some wastewater can achieve good results through Fenton oxidation, and some may not be affected by oxidation.
[0004] This results in the need for different treatment systems for wastewater with different component ratios, or the need for frequent adjustment and modification of the treatment system, which is time-consuming and labor-intensive and cannot achieve good treatment results. UTILITY MODEL CONTENT
[0005] Technical problem: In view of the above problems existing in the prior art, the technical problem to be solved by the utility model is that a raw material medicine production organic wastewater treatment device can treat most organic wastewater.

[0013] Furthermore, the filter box is equipped with a support mesh plate, the filter mesh groove is slidably connected to the support mesh plate, the filter box has a door on its side wall, and the filter box is equipped with a water inlet pipe.
[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:
[0015] 1.

[0023] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0024] like Figure 1 and Figure 2 As shown, an organic wastewater treatment device for pharmaceutical raw material production includes a filter box 1, a first treatment box 2, and a second treatment box 3. The filter box 1 is equipped with an inlet pipe 96, which has a flange for connecting to an external pipeline. Organic wastewater generated during pharmaceutical raw material production enters the filter box 1 through the inlet pipe 96. The filter box 1 contains a filter screen groove 11 and a support screen plate 12. The support screen plate 12 is positioned near the outlet of the filter box 1 and has a sliding groove. The filter screen groove 11 is a rectangular groove with filter holes. The bottom of the filter screen groove 11... The filter box 1 is equipped with a slider that slides on a groove. The filter screen groove 11 is slidably connected to the support mesh plate 12. The side wall of the filter box 1 is equipped with a door 13, which is hinged to the filter box 1. Organic wastewater is filtered by the filter screen groove 11, and impurities are left in the filter screen groove 11. The door 13 is opened periodically to remove the filter screen groove 11 for cleaning or replacement. Multiple filter screen grooves can be set. Setting up filter screen grooves 11 can quickly perform preliminary filtration of organic wastewater, ensuring that impurities can be filtered out at the first time, effectively improving the subsequent purification efficiency of organic wastewater.
[0025] like Figure 1 and Figure 3 As shown, the first treatment box 2 is connected to the filter box 1. The first treatment box 2 is equipped with an iron-carbon reduction box 4, an oxidation box 5 and a collection tank 51. The lower end of the filter box 1 is connected to the iron-carbon reduction box 4 through the first connecting pipe 91. The iron-carbon reduction box 4 is equipped with iron-carbon packing 41. Organic wastewater enters the iron-carbon reduction box 4 from the filter box 1 and comes into contact with the iron-carbon packing 41. The bottom of the iron-carbon reduction box 4 is equipped with multiple ultrasonic transducers 42. When the ultrasonic transducers 42 are activated, a micro-electrolysis battery reaction is carried out. After the reaction, high-concentration organic matter in the wastewater can be efficiently removed. The iron-carbon reduction tank 4 is connected to the oxidation tank 5 via the second connecting pipe 92. The collection tank 51 is installed on the oxidation tank 5 and is connected to the oxidation tank 5 via the transfer pump 52. When wastewater enters the oxidation tank 5, the transfer pump 52 works to transport 3-30% H2O2 and 10% ferrous sulfate from the collection tank 51 into the oxidation tank 5 to remove recalcitrant organic pollutants. In the first treatment tank 2, iron-carbon reduction and catalytic oxidation are combined to improve the biodegradability of the wastewater and meet the needs of subsequent biochemical treatment.
[0026] like Figure 1 and Figure 4As shown, the second treatment tank 3 is equipped with a Fenton reaction tank 6 and an activated carbon filter box 7. The oxidation tank 5 is connected to the Fenton reaction tank 6 via a third connecting pipe 93. An ozone dispenser 61 is connected to the Fenton reaction tank 6. A pH detector 62 is installed on the bottom wall of the Fenton reaction tank 6. When wastewater enters the Fenton reaction tank 6 through the third connecting pipe 93, the ozone dispenser 61 works to transfer ozone into the Fenton reaction tank 6, while the pH detector 62 at the bottom starts to detect the pH value of the wastewater inside. Ozone replaces the hydrogen peroxide in the original Fenton reaction. Under the catalysis of ferrous ions, the same amount of ozone and hydrogen peroxide produce approximately three times more hydroxyl groups than hydrogen peroxide, thus ozone has a stronger oxidizing ability and effectively improves the Fenton effect of the Fenton reaction tank 6. The Fenton reaction vessel 6 is connected to the activated carbon filter box 7 via the fourth connecting pipe 94. The activated carbon filter box 7 contains activated carbon, and a water outlet pipe 95 is provided on the bottom of the side wall of the activated carbon filter box 7. Wastewater filtered by the activated carbon is discharged from the water outlet pipe 95.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, a first solenoid valve 81 is installed on the second connecting pipe 92, a second solenoid valve 82 is installed on the third connecting pipe 93, a third solenoid valve 83 is installed on the fourth connecting pipe 94, and a fourth solenoid valve 84 is installed on the water outlet pipe 95. A controller 8 is installed on the first treatment tank 2. The controller 8 is electrically connected to the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83, and the fourth solenoid valve 84, thereby controlling the opening and closing of these solenoid valves. The controller 8 is also electrically connected to the ultrasonic transducer 42, the delivery pump 52, and the ozone dispenser 61, thereby controlling their operation.
[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
