Embodiment 1

[0019] A kind of heparin sodium wastewater treatment process, comprises the steps:

[0020] S1. After the heparin sodium wastewater is adsorbed by resin beads, the suspended beads and scum in the wastewater are removed through the first-stage air flotation and the second-stage air flotation, and the water from the air flotation flows into the electrodialysis system to obtain the first concentrated solution respectively and desalted solution, the first concentrated solution is reused, and the desalted solution enters the A / O biochemical pool, and after anaerobic and aerobic treatment, it enters the MBR pool added with betaine. The concentration of betaine added is 1 mmol / L, and the biochemical treatment Finally, after being filtered by the MBR membrane, it enters the ultrafiltration system and the reverse osmosis system in turn, and the effluent is the standard water.

[0021] In this embodiment, the resin beads are composed of several superabsorbent polymer resin balls, a sili...

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a heparin sodium wastewater treatment process which comprises the following steps: carrying out resin bead adsorption treatment on heparin sodium wastewater, sequentially carrying out primary air floatation and secondary air floatation to remove suspended beads and scum in the wastewater, enabling air floatation effluent to automatically flow into an electrodialysis system to respectively obtain a first concentrated solution and a desalted solution, recycling the first concentrated solution, enabling the desalted solution to enter an A / O biochemical pool for anaerobic and aerobic treatment, to enter an MBR pool added with betaine for biochemical treatment, carrying out MBR membrane filtration, and sequentially enabling the solution to enter an ultrafiltration system and a reverse osmosis system, so that effluent is standard water. The method is good in treatment and purification effect and high in efficiency, the treated wastewater can reach the standard to be discharged, pollution to the environment is avoided, and meanwhile the recovery rate of protein is increased.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a heparin sodium wastewater treatment process. Background technique [0002] Heparin sodium is a natural anticoagulant drug with a wide range of biological functions and medicinal value, such as anticoagulation, clarifying blood lipids, lowering cholesterol, anti-inflammation, anti-allergy, anti-virus and lowering blood lipids, etc., so the demand is increasing year by year Increase. The production process of heparin sodium includes: raw material treatment, enzymatic hydrolysis extraction, ion exchange adsorption, refining and other processes. During the production process, due to the extensive use of acid and alkali, a large amount of salty wastewater will be discharged, the discharge amount is about 500-2500 tons (wastewater) / ton (product), and the wastewater components include: 92-96% (W / W) , sodium chloride 2.0-5.0% (W / W), organic matter 2.0-3.0% (W / W), total p...
