Problems solved by technology

At present, domestic pharmaceutical factories mostly incinerate oxytetracycline residues and temporarily dry and store them. However, the cost of incineration is high and secondary pollution such as dioxins will be generated, and the area occupied by drying and storage is relatively large.

Embodiment 1

[0031]Take 2L of oxytetracycline slag and add it to the oxytetracycline slag reserve pool 1 (the slag itself contains water and is in a fluid state), and add 0.10mol / L NaOH lye to the lye tank 2; Time control opens metering pump one 10 and metering pump two 18 connected to each other with oxytetracycline slag reserve tank 1 and lye tank 2, and now alkali lye and oxytetracycline slag in the alkali-thermal pre-reaction tank 3 are in mass ratio of 0.10gNaOH / g, the feed amount of oxytetracycline bacterium slag is 3% of anaerobic ASBR reactor 6 volumes; Open the electric agitator 4 25 in the alkali-thermal pre-reaction tank 3 to stir, and heating belt 12 starts heating simultaneously, adopts temperature probe 13 Detect the actual temperature in the alkali-thermal pre-reaction tank 3, and feed it back to the temperature control box 14. When the temperature is less than 85°C, the heating belt 12 starts heating. When the temperature reaches 85°C, the heating stops, and the alkali-heat ...

Embodiment 2

[0033] Take 2L of oxytetracycline slag and add it to oxytetracycline slag reserve pool 1, and add 0.10mol / L NaOH lye into lye tank 2; The metering pump one 10 that liquid tank 2 links to each other, metering pump two 18, alkali liquor and oxytetracycline slag are 0.12gNaOH / g by mass ratio in the alkali-heat pre-reaction tank 3 now, and oxytetracycline slag feed rate is 3.5% of anaerobic ASBR reactor 6 volumes; Open electric agitator 4 25 in the alkali-thermal pre-reaction tank 3 and stir, and heating belt 12 starts heating simultaneously, adopt temperature probe 13 to detect the actual temperature in the alkali-thermal pre-reaction tank 3, and Feedback to the temperature control box 14, when the temperature is less than 85°C, the heating belt 12 starts to heat, and when the temperature reaches 85°C, the heating stops, and the stirring time in the alkali-thermal pre-reaction tank 3 is set to 3h; After the alkali-thermal pretreatment, it is injected into the adjustment tank 4 th...

Abstract

The invention belongs to the technical field of environmental protection, and relates to an oxytetracycline mushroom residue harmless treatment device and technology. The oxytetracycline mushroom residue harmless treatment device comprises an oxytetracycline mushroom residue storage tank, an alkali liquid tank, an alkaline heating pre-reaction tank, an adjustment tank, an acid liquid tank, an ASBR (Anaerobic Sequencing Batch Reactor), an excess sludge storage tank, a biogas residue collecting tank which are used as main bodies, and also comprises a temperature probe, a water quality online monitoring system and the like, wherein the temperature probe is connected to a temperature control box. The oxytetracycline mushroom residue harmless treatment technology comprises the following steps: firstly injecting oxytetracycline mushroom residues and alkali liquid to the alkaline heating pre-reaction tank for pretreating, then putting mixed liquid in the adjustment tank, adjusting pH, putting in the ASBR, simultaneously injecting excess sludge to an anaerobic reactor so as to adjust a C / N ratio, recycling marsh gas generated after anaerobic digestion, which is used as clean fuel, and discharging harmless biogas residues into the biogas residue collecting tank, which are used as raw materials for preparing organic fertilizer. The oxytetracycline mushroom residue harmless treatment device and technology have the advantages that the utilization efficiency of the oxytetracycline mushroom residue organic materials is improved, and the harmless treatment and resource utilization of the oxytetracycline mushroom residues are realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device and a process for harmless treatment of oxytetracycline slag. Background technique [0002] my country is a major producer of antibiotics. In 2011, my country's antibiotic output was 1.116 million tons, accounting for more than 70% of the global market. Among them, the annual output of oxytetracycline accounts for 90% of the global output. According to the estimate of 8-10 tons of wet fungal residue produced by 1 ton of antibiotics, the annual production of oxytetracycline fungal residue in my country is more than 150,000 tons. If it is not disposed of properly, it will seriously endanger the ecological environment and human health. Announcement No. 176 jointly issued by the Ministry of Agriculture, the Ministry of Health and the State Drug Administration in February 2002 stipulates that antibiotic waste bacteria residues are listed as drugs...
