Embodiment 1
[0089] Embodiment 1: Enhanced hydrolysis-AnMBR technology to process oxytetracycline production waste mother liquor
[0090] 1. Enhanced hydrolysis
[0091] 1-1. Under stirring, add concentrated sodium hydroxide solution to the waste mother liquor produced by oxytetracycline, and adjust the pH of the waste mother liquor to 7 (usually the pH is 5 to 7, preferably 7);
[0092] 1-2. Pass the pH-adjusted waste mother liquor into the heat exchanger, and preheat the waste mother liquor so that the temperature of the waste mother liquor rises to 60°C (usually 40-60°C); then heat treatment , heating the waste mother liquor until the temperature of the waste mother liquor rises and remains at 110°C (usually 85-160°C), and the waste mother liquor is subjected to enhanced hydrolysis treatment at a temperature of 110°C (usually 85-160°C). Hydrolysis treatment time 1h (usually 0.5 ~ 6h);
[0093] The method of the present invention gradually raises the temperature of antibiotic pharmaceu...
Embodiment 1A
[0134] Embodiment 1A: Enhanced hydrolysis-AnMBR technology treatment of fermented oxytetracycline-like production waste mother liquor
[0135] 1. Enhanced hydrolysis
[0136] Same as Step 1 of Example 1.
[0137] 2. Preprocessing of AnMBR
[0138] Except that the flow rate of biogas aeration is 2L / min, and the thickness of the microbial film evenly loaded on the surface of the filter membrane is 1.0mm, the rest is the same as step 2 of Example 1.
[0139] 3. AnMBR processing
[0140] Same as Step 3 of Example 1.
[0141] The initial transmembrane pressure difference is -3.42kPa. Measure the COD of AnMBR inlet and outlet water; measure the pH of the outlet water, the content of volatile fatty acids, and methane production, record the working / rest time of the membrane, measure the transmembrane pressure difference and the first membrane washing cycle, and the measurement results are shown in Tables 1 and 2.
Embodiment 1B
[0142] Example 1B: Enhanced hydrolysis-AnMBR technology to treat waste mother liquor produced by fermented oxytetracycline
[0143] 1. Enhanced hydrolysis
[0144] Same as Step 1 of Example 1.
[0145] 2. Preprocessing of AnMBR
[0146] Except that the flow rate of biogas aeration is 0.5 L / min, and the thickness of the microbial film uniformly loaded on the surface of the filter membrane is 2.0 mm, the rest is the same as step 2 of Example 1.
[0147] 3. AnMBR processing
[0148] Same as Step 3 of Example 1.
[0149] The initial transmembrane pressure difference is -8.68kPa. Measure AnMBR inlet and outlet water COD; measure outlet water pH, volatile fatty acid content, methane production, record membrane working / rest time, measure transmembrane pressure difference and the first membrane washing cycle, and the measurement results are shown in Tables 1 and 2.
[0150] Based on the results of Examples 1-1B, for the treatment effect of AnMBR, that is, from the perspective of ...
