Medicinal auxiliary material production wastewater treatment technology

Abstract

The invention discloses a medicinal auxiliary material production wastewater treatment technology, and relates to the treatment of wastewater in the medicinal auxiliary material preparation field. The technology comprises the following steps: wastewater is discharged to an equalizing tank I, and microcrystalline wastewater is discharged to an equalizing tank II; wastewater from the equalizing tank I is lifted to a coagulation precipitation tank I through a pump, and the obtained wastewater enters a Fenton catalytic oxidation tank for a reaction; and wastewater from the equalizing tank II and water discharged from the Fenton catalytic oxidation tank enter a coagulation precipitation tank II water discharged from the coagulation precipitation tank II and domestic sewage enter a homogenization tank and are uniformly mixed, the obtained water mixture enters a hydrolysis acidifying tank and then enters an intermediate water tank, wastewater from the intermediate water tank is lifted to an EGSB reaction tower, water discharged from the EGSB automatically flows to a bio-contact oxidation tank, water discharged from the bio-contact oxidation tank is discharged to a coagulation precipitation tank III, water discharged from the coagulation precipitation tank III is sent to a sand filter, and water from the sand filter is discharged to a clear water pool for standard reaching discharge. The medicinal auxiliary material production wastewater treatment technology has the advantages of simplicity, less energy consumption, low operation cost, stable and reliable treatment effect, strong impact load resistance ability, and realization of highest COD removal rate reaching above 90%.

Description

technical field [0001] The invention relates to the treatment of wastewater in the field of manufacturing pharmaceutical excipients, in particular to a process and device for treating wastewater produced in pharmaceutical excipients, which belongs to relatively difficult to degrade, high-concentration, and high-salt organic wastewater. Background technique [0002] Pharmaceutical excipients are an important part of pharmaceutical preparations, and their role is to ensure that the drug is selectively transported to the tissue in a certain way and procedure so that the drug is released in the body at a certain speed and time. Therefore, the selection of appropriate excipients is one of the key factors for the efficacy of pharmaceutical preparations. Pharmaceutical excipients have huge market prospects. According to statistics, the average growth rate of sales of pharmaceutical excipients has been 15% since the late 1990s, especially in the past two years. The growth rate will ...
