Problems solved by technology

Moreover, the waste water of pharmaceutical factories is usually discharged intermittently, and the types and quantities of products vary greatly, resulting in great changes in the quality, quantity and types of pollutants of waste water, which brings great difficulties to the treatment.
The general traditional sewage and wastewater treatment process can no longer meet the treatment requirements of pharmaceutical wastewater in today's society

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is further described:

[0020] Such as figure 1 The pharmaceutical wastewater treatment method shown includes the following steps: (1), the pharmaceutical wastewater is sent into the grid for preliminary filtration, and then pumped into the regulating pool for regulating treatment; (2), the wastewater in the regulating pond After adjustment and treatment, it is sent to the air flotation tank; (3), the wastewater in the air flotation tank is treated and then enters UASB for anaerobic treatment; (4), the wastewater treated by UASB is sent to the pre-aeration sedimentation tank to remove anaerobic (5) The wastewater treated in the pre-exposure sedimentation tank is treated with SBR, and the treated water can be discharged; PAV is added to the adjustment tank; PAM is added to the adjustment tank; Plant protein can be recycled; the biogas produced after UASB treatment is sent to the biogas digester for ut...

Abstract

The invention discloses a pharmaceutical wastewater treatment method in the field of pharmaceutical wastewater treatment. The method includes the following steps: (1) pharmaceutical wastewater is sentinto a grid for preliminary filtration and then pumped into a regulating tank for regulation treatment; (2) the wastewater in the regulating tank is sent into an air floatation tank after the regulation treatment; (3) after being treated in the air floatation tank, the wastewater enters a UASB for anaerobic treatment; (4) the wastewater treated by the UASB is sent into a pre-exposure sedimentation tank to remove suspended matters which has difficulty in being decomposed in an anaerobic tank; and (5) SBR treatment is carried out on the wastewater treated by the pre-exposure sedimentation tank,and the water after the treatment can be discharged. The difficulties of intermittent discharge and great variety and quantity change of products can be overcome by sending the pharmaceutical wastewater into the grid, regulating tank, air floatation tank, UASB, pre-exposure sedimentation tank and SBR in order for treatment, and the pharmaceutical wastewater can be treated well, which meets treatment requirements of the pharmaceutical wastewater in today's society. The pharmaceutical wastewater treatment method can be used in pharmaceutical wastewater treatment.

Description

technical field [0001] The invention relates to a wastewater treatment method, in particular to a pharmaceutical wastewater treatment method. Background technique [0002] At present, with the rapid development of the pharmaceutical industry, the pollution control of pharmaceutical wastewater is becoming more and more serious. Pharmaceutical wastewater is one of the difficult-to-treat industrial wastewater. Due to different types of drugs and different production processes, it has the characteristics of large composition differences, complex components, large amount of pollutants, high COD, many refractory substances, and strong toxicity. Moreover, wastewater from pharmaceutical factories is usually discharged intermittently, and the types and quantities of products vary greatly, resulting in large changes in the quality, quantity and types of pollutants of wastewater, which brings great difficulties to treatment. Generally, the traditional sewage treatment process can no l...
