specific Embodiment approach 1

[0046] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the electric-assisted microbial enhanced degradation high-concentration pharmaceutical wastewater treatment device in this embodiment includes a water inlet 1, a water outlet 2, a box body 3, a top cover 4, a water quality monitoring port 5, a plexiglass plate 6, a carbon fiber brush 8, Titanium wire 9, air collecting pipe 7, wet gas flow meter 10, water-sealed bottle 11, mud hopper 12 and mud discharge port 13, the box body 3 includes eight compartments, respectively the first compartment 3-1, The second compartment 3-2, the third compartment 3-3, the fourth compartment 3-4, the fifth compartment 3-5, the sixth compartment 3-6, the seventh compartment 3-7 and the eighth compartment Compartments 3-8, adjacent compartments are separated by partitions, the lower end of the partition between the first compartment 3-1 and the second compartment 3-2 is provided with a communication ho...

specific Embodiment approach 2

[0053] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that there are 2 to 4 water quality monitoring ports outside each compartment, which are respectively arranged on the upper and lower parts outside each compartment, sequentially from top to bottom arrangement. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0054] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: each carbon fiber brush 8 is cylindrical, with a diameter of 2-4 cm. Others are the same as in the first or second embodiment.

[0055] A titanium wire is arranged at the center of the carbon fiber brush 8 to fix the carbon fiber brush. In addition, the titanium wire also has the functions of conducting electricity and preventing corrosion.

Abstract

The invention provides a device for treating high-concentration pharmaceutical wastewater through electric power assisted microbial enhanced degradation and a method for treating the pharmaceutical wastewater, relates to a pharmaceutical wastewater treatment device and a pharmaceutical wastewater treatment method adopting the device and aims to solve the technical problems of low toxicity removal rate and poor COD (chemical oxygen demand) removal capacity of a conventional high-concentration pharmaceutical wastewater treatment method. The device comprises a water inlet, a water outlet, a tank body, a top cover, water quality monitoring ports, organic glass sheets, carbon fiber brushes, titanium wires, a gas collecting pipe, a wet gas flow meter, a water seal tank, a sludge deposit hopper and a sludge drain port. The method comprises steps as follows: step one, sludge is sieved by a screen, pharmaceutical wastewater is added to the sludge, NaH2PO3 and NH4Cl are added, acclimatization is performed for 2 weeks, and a mixture after acclimatization is added to each isolation chamber of the pharmaceutical wastewater treatment device; step two, the titanium wires are connected with a transformer, the device operates in a sequencing batch type mode, then the operating mode is changed into a continuous water feeding mode, water is discharged from the water outlet, and the water treatment process is finished. The device and the method are applied to the field of sewage treatment.

Description

technical field [0001] The invention relates to a pharmaceutical wastewater treatment device and a method for treating pharmaceutical wastewater by using the device. Background technique [0002] The problem of water pollution has always existed and has threatened the sustainable development of the entire society. Water pollution control must be put on the agenda. According to statistics from the Ministry of Environmental Protection, in 2012, the total discharge of wastewater in the country was 68.43 billion tons, the highest in the past years, and the discharge of industrial wastewater alone accounted for 32.4%. the vast majority of. Due to the low utilization rate of raw materials and low extraction purity in the current production process of the pharmaceutical industry, a large amount of highly toxic and refractory organic substances remain in the pharmaceutical wastewater, which is bound to cause serious pollution to the environment. Toxic substances in pharmaceutical ...
