Abstract

The invention discloses a fermentation wastewater processing method and biological feed. The method includes the following processing steps of conducting centrifugal separation on fermentation wastewater through a centrifugal machine to obtain clean liquid and concentrated liquid, wherein the biomass concentration of the concentrated liquid is larger than the biomass concentration of the clean liquid; sending the concentrated liquid into a drying tower to be subjected to spray drying, and obtaining dry powder; sending the clean liquid into a sewage processing system, regulating PH of the clean liquid in the sewage processing system to be neutral, conducting biochemical processing on the clean liquid, and discharging the clean liquid. In this way, the separated clean liquid is sent into the sewage processing system, the COD and the suspended matter content in fermentation wastewater are lowered, the technical problem that the normal biochemical reaction is not facilitated after fermentation wastewater directly enters the sewage processing system is solved, and therefore loads of subsequent sewage processing are reduced, and remarkable environment protection benefits are achieved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a fermentation wastewater treatment method and biological feed. Background technique [0002] Fermentation wastewater is a high-concentration organic waste liquid, which is rich in protein, amino acids, vitamins, sugars and various trace elements. It has the characteristics of high concentration, high suspended solids, high viscosity, and refractory degradation, making the treatment of this type of wastewater very difficult. big. [0003] It is a brand-new technology to use biological fermentation to directly convert industrial gas in iron and steel plants into ethanol. The industrial wastewater generated during the production process mainly comes from two parts: one is the mature mash directly produced during the fermentation process, and the other is the fermentation The tower still wastewater after the mash is treated by the rectification tower, this kind of fermentation w...
