Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a device for treating wastewater produced in the production of adenosine cyclic phosphate injection. BACKGROUND

[0002] In the field of biochemical pharmaceuticals such as adenosine cyclic phosphate, the production wastewater is complex in composition, high in pollutant concentration, and difficult to treat. Such wastewater usually contains high concentrations of proteins, residual medium components, microbial cell fragments, incompletely converted organic intermediates, and part of the solvent, etc. These substances result in wastewater with high COD (chemical oxygen demand), high BOD (biochemical oxygen demand), and good biodegradability, but also bring two major pretreatment problems. First, the dissolved proteins and surfactants in the wastewater are prone to produce a large amount of stable and viscous protein foam (protein foam) during subsequent aerobic aeration or stirring. These protein foams cover the liquid surface, seriously hindering the mass transfer efficiency of oxygen to the water body, resulting in increased aeration energy consumption and decreased biochemical reaction rate. At the same time, the protein foam can wrap a large amount of active sludge microorganisms escaping from the system, causing biomass loss and destroying the stability of the treatment system. The accumulated protein foam can also undergo anaerobic putrefaction, producing foul-smelling gases and deteriorating the operating environment.

[0003] Secondly, the wastewater contains a large amount of suspended matter with a relatively low specific gravity, such as denatured protein flocculation, zooglea, and small biochemical sludge clumps. These substances have poor settling performance in traditional pretreatment reaction tanks and are easily carried into the subsequent core biological treatment unit (such as a biological reactor) with the water flow. They not only consume dissolved oxygen inefficiently and compete with functional microorganisms for nutrients, but also seriously affect the efficiency of biological treatment.
