Problems solved by technology

[0003] The content of organic matter in the dry base of streptomycin slag can reach about 90%, which can be used as a kind of biomass energy and has the potential of biochemical treatment. At present, most of the streptomycin slag is incinerated or temporarily baked in domestic pharmaceutical factories. Dry storage, these disposal methods pay too much attention to harmlessness, waste a lot of available resources in the fungal residue, and do not meet the concept of circular economy and the requirements of scientific development

Embodiment 1

[0055] Take 2L of streptomycin slag and add it to the streptomycin slag storage tank, set the feed amount to 5% of the volume of the anaerobic ASBR reactor (6), and add 0.15mol / L NaOH lye to the alkali tank (14); through the PLC automatic control system (8) to control the opening of the streptomycin slag storage tank (1) and the alkali adding pump (26), the feeding time is set to 5min, and the flow rates are 0.05L / min and 0.001L respectively / min, the mass ratio of lye and streptomycin slag in the pre-reaction zone was 0.08gNaOH / g streptomycin slag at this time; the electric stirrer one (121) in the pre-reaction tank (3) was opened, and the heating rod One (181) starts heating, uses the online water quality monitoring system one (111) to detect the actual temperature in the pre-reaction tank (3), and feeds back to the PLC automatic control system, when the temperature is lower than 75°C, the heating rod one (181) starts heating , when the temperature reaches 75°C, the heating ...

Embodiment 2

[0057] Take 2L of streptomycin slag and add it to the streptomycin slag storage tank, set the feed amount to 4.5% of the volume of the anaerobic ASBR reactor (6), and add 0.15mol / L NaOH lye to the alkali tank (14); through the PLC automatic control system (8) to control the opening of the streptomycin slag storage tank (1) and the alkali adding pump (26), the feeding time is set to 5min, and the flow rates are 0.05L / min and 0.001 L / min, now the mass ratio of lye and streptomycin slag in the pre-reaction zone is 0.10gNaOH / g streptomycin slag; electric stirrer one (121) in the pre-reaction tank (3) is opened and heated simultaneously Rod 1 (181) starts heating, and uses online water quality monitoring system 1 (111) to detect the actual temperature in the pre-reaction tank (3), and feeds back to the PLC automatic control system. When the temperature is lower than 75°C, heating rod 1 (181) starts Heating, when the temperature reaches 75°C, the heating is stopped, and the stirring t...

Abstract

The invention belongs to the technical field of anaerobic biological treatment, and in particular relates to a treating device and a treating method for streptomycin dregs. The device comprises a streptomycin dreg storage reservoir, an alkali liquor tank, a pre-reaction reservoir, a regulating reservoir, a straw fermentation reservoir, an ASBR (anaerobic sequencing batch reactor), a biogas residue colleting tank, a PLC (programmable logic controller) auto-control system and an online water quality monitoring system. The method is automatically finished by using the computer PLC auto-control system and comprises the following steps: firstly injecting streptomycin dregs and alkali liquor in the pre-reaction reservoir, heating to pre-heat the alkali, placing the pre-treated mixed liquor in the regulating reservoir, regulating the C / N ratio and pH by using the straw fermenting liquor, placing in the ASBR, recycling the biogas produced after anaerobic digestion as the cleaning fuel, discharging dregs which are identified as harmless into a biogas residue colleting tank as the raw material for manufacturing an organic fertilizer. The device and method provided by the invention are capable of improving the utilization rate of the organic matter of the streptomycin dregs, and realizing the harmless and reutilization of the streptomycin dregs.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment and anaerobic biological treatment, and in particular relates to a treatment device and method for streptomycin residue. Background technique [0002] Streptomycin residue is mainly composed of mycelium, remaining medium, and fermentation metabolites, which contain a large amount of residual antibiotics, polysaccharides, proteins, various amino acids and trace elements, according to the revised "National Hazardous Waste List" in 2008 , Antibiotic bacteria residues belong to the culture medium waste in the production process of chemical raw materials, and must be managed as hazardous waste. At present, the production of antibiotics in my country accounts for more than 70% of the total global market, and the annual output of streptomycin accounts for more than 90% of the global production. According to the estimation of 8-10 tons of wet fungus residue produced by 1t of streptomycin, in...
