I. Wastewater quality and quantity:
The source of wastewater is mainly the production wastewater generated from the production of cephalosporin antibiotics. The main raw material used is 7-ACA. 7-ACA has a molecular formula of C10H12N2O5S and a molecular weight of 272.28. The chemical name of 7-ACA is 3-acetoxymethyl-5-thio-7-amino-8-oxo-1-azabicyclooct-2-ene- 2 carboxylic acid is cephalosporin C obtained from cephalosporin fermentation of corn slurry. Cephalosporin C is hydrolyzed at the amide bond to obtain 7-AcA. Its structure is as follows:
Inlet water volume: 100m3 / d, designed to operate 24 hours a day
Inlet water quality
After treatment, the sewage reaches the first-level discharge standard stipulated in the Comprehensive Sewage Discharge Standard.
Third, the process:
1. Electricity charges
100m3 of wastewater per day, calculated at 0.50 yuan / Kw.h
The electricity cost per ton of water: 406.7 ¡Á 0.50 ¡Â 100 = 2.03 yuan
A sewage treatment station is set up for one person, with a monthly salary of 1,500 yuan per person, and a daily treatment of 100m3 of wastewater.
Labor cost: 0.5 yuan
Sewage treatment plant operation fee per ton of water costs 0.20 yuan
Sewage treatment plant daily operation ton water treatment fee: 2.73 yuan.
