A kind of endogenous antibiotic waste water treatment process system

Abstract

The invention provides an internal consumption antibiotic wastewater treatment process system, comprising a mechanical grid, a primary adjustment tank, a neutralization tank, a coagulation tank, a primary internal consumption tank, a primary sedimentation tank, a secondary internal consumption tank, a primary ozone reaction tank, a secondary Conditioning tank, anaerobic system, aerobic system, secondary sedimentation tank and secondary ozone reaction tank. In the invention, the residual sludge of the system is used as an adsorbent for secondary utilization, and the biological toxicity of antibiotics in the wastewater is used to kill the microorganisms in the residual sludge, so as to achieve the effect of disinfection and stabilization of the residual sludge, and to treat waste with waste. In addition, the residual sludge and antibiotics are both original or generated harmful substances in the system, and the principle of mutual restraint between the two is used to achieve the effect of effective internal friction. The invention effectively reduces the dosage of the medicine and the power consumption, and saves the economic cost.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to an endogenous antibiotic waste water treatment process system. Background technique [0002] At present, antibiotics are widely consumed in China. Most antibiotics are biological products, that is, they are extracted through fermentation process. They are compounds produced by microorganisms, plants, and animals in their life processes. They have the ability to selectively inhibit It is an important chemical drug for humans to control infectious diseases, ensure health, and prevent and control animal and plant diseases. At present, there are more than 300 enterprises producing antibiotics in my country, and the production of 70 varieties of antibiotics accounts for 20% to 30% of the world's output. [0003] In the production process of antibiotics in my country, most of them have the characteristics of low raw material utilization rate, low refining purity, and hig...

AI Technical Summary

Problems solved by technology

The advanced oxidation method has fast reaction speed, high treatment efficiency and wide application range, but the treatment cost is high, the reactor is complicated, the reaction conditions are strict, and there are by-products; Odor, but the cost is high, and the effluent will carry large and shedding biofilms; the traditional activated sludge method has high treatment capacity and good effluent quality, but the construction and operation costs are high, energy consumption is large, management is complicated, and sludge is prone to appear Swelling issues; activated carbon adsorption has no by-products but is more expensive

The comparison found that the treatment costs of these methods are high and the management is complicated. Except that the removal rate of antibiotics by the advanced oxidation method can reach 95%, the removal rates of other antibiotics are relatively low

A single treatment method has certain limitations in the treatment of antibiotic wastewater. Only combined treatment processes can better treat antibiotic wastewater and ensure that the treated water can meet the discharge standards.

[0005] In addition, the conventional biochemical process used in the treatment of antibiotic wastewater has a large amount of excess sludge discharged, and it is treated as hazardous waste, which requires a separate disinfection pretreatment before it can be transported for disposal, which further increases the operating cost
