Problems solved by technology

The pharmaceutical industry is one of the sources of industrial sewage. Pharmaceutical sewage includes four types of sewage, namely, organic synthetic drug sewage, inorganic synthetic drug sewage, antibiotic sewage and herbal medicine production sewage. And the characteristics of toxic substances that inhibit the living organisms and intermittent discharge, most manufacturers directly discharge without treatment, causing serious harm to the water environment

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] A method for treating pharmaceutical sewage, comprising the steps of:

[0021] (1) The sewage first passes through the grill to remove the larger floating objects to ensure the normal operation of subsequent structures and equipment;

[0022] (2) Then enter the hydrolysis acidification adjustment tank through the lifting pump, equalize the water quality and water quantity, and degrade a part of CODcr and chromaticity, wherein, the solid matter is degraded into soluble matter, and the macromolecular matter is degraded into small molecular matter;

[0023] (3) Gravity then enters the biological contact oxidation tank, where the sewage undergoes aerobic biochemical reaction, semi-soft filler is installed in the biological contact oxidation tan...

Abstract

The invention discloses a pharmaceutical wastewater treatment method. The method includes steps: wastewater flows through a grille to remove large floating materials so as to guarantee normality in subsequent operation of structures and equipment; the wastewater enters a hydrolytic acidification adjusting tank through a lift pump to balance water quality and water quantity and degrade part of CODcr and chromaticity, wherein solid substances are degraded into soluble substances, and macromolecular substances are degraded into micromolecular substances; then the wastewater flows into a biological contact oxidation tank in which the wastewater is subjected to aerobic biochemical reaction, biological contact oxidation tank is internally provided with semi-soft filler, and a submerged aerator is adopted for oxygenation and stirring to realize degradation of organic pollutants; the wastewater enters a sedimentation tank after a flocculating agent is added to realize sedimentation of shed biological membranes and fine suspension substances in the sedimentation tank; finally, the wastewater is filtered through activated carbon to remove residual colors and organics in water, so that up-to-standard emission can be realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pharmaceutical sewage treatment method. Background technique [0002] The pharmaceutical industry is a traditional pillar industry in my country. With the rapid development of the national economy, pharmaceutical companies have developed rapidly. The pharmaceutical industry is one of the sources of industrial sewage. Pharmaceutical sewage includes four types of sewage, namely, organic synthetic drug sewage, inorganic synthetic drug sewage, antibiotic sewage and herbal medicine production sewage. These sewage have high concentration, deep color, refractory As well as the characteristics of toxic substances that have an inhibitory effect on organisms and intermittent discharge, most manufacturers discharge them directly without treatment, causing serious harm to the water environment. Contents of the invention [0003] The technical problem to be solved by the present...
