Description

Technical Field

[0001] The invention relates to the technical field of treatment of waste gas, waste water and waste residue generated in the production process of antibiotics in the pharmaceutical industry, and specifically to a system for coordinated treatment of three wastes in the production process of lincomycin. Background Art

[0002] Antibiotics, also known as antimicrobials, refer to a class of secondary metabolites produced by microorganisms (including bacteria, fungi, and actinomycetes) or higher animals and plants in their life processes that have anti-pathogen or other activities, and are chemical substances that can interfere with the developmental functions of other living cells. Lincomycin, also known as lincomycin, is a secondary metabolite produced by the fermentation of Streptomyces lincomycin. At present, lincomycin is mainly produced by fermentation, and the finished product is obtained through fermentation, filtration, extraction, concentration, crystallization, drying and other processes. In this process, a large amount of fermentation waste gas, waste residue and wastewater will be generated.

[0003] Fermentation waste gas often has the characteristics of large air volume, low concentration, and strong odor. If it is treated directly, the treatment volume is too large, and multiple sets of equipment will inevitably be used in conjunction, resulting in high equipment investment costs and high energy consumption during operation. The waste liquid generated in the production process of lincomycin often contains difficult-to-biodegrade components. This part of the waste liquid is currently directly sent out for treatment or concentrated by MVR technology before being sent out. First of all, a large amount of steam will be used in the MVR technology treatment process, which consumes a lot of energy. Secondly, external delivery will also lead to an increase in treatment costs. In addition, sludge will be produced in multiple sections such as the intermediate sedimentation tank, anaerobic section, sedimentation tank, and final sedimentation tank. How to further treat this part of the pollutants to ensure that the entire system is environmentally friendly and the pollutants are close to zero discharge is also a problem to be solved. In the process of fermentation residue treatment, there are mainly problems such as the presence of toxic and harmful residues inhibiting the degradation of fermentation residue, and the high water content leading to high dehydration energy consumption.

[0004] It can be seen that in the process of treating the waste gas, waste liquid and waste residue generated in the production process of lincomycin, high operating costs and high energy consumption are a major problem. In addition, the separate treatment of the three wastes is bound to produce two other types of pollutants. For example, some waste liquid will be produced during the waste gas spray pretreatment process, and some solid waste will be produced during activated carbon adsorption; a large amount of waste gas will be produced in each treatment pool during the waste liquid treatment process, more solid waste will be produced after sludge concentration, and high-concentration waste liquid will be produced after efficient evaporation; waste liquid and waste gas will be produced during the waste residue treatment process. Therefore, even if the high energy consumption is not taken into account, the separate treatment of the three wastes can meet their respective emission standards, but because of the generation of other pollutants, it is impossible to achieve environmental friendliness and near-zero pollutant emissions.

[0005] Relevant technologies for the separate treatment of waste liquid, waste residue and waste gas generated in the production process of lincomycin have been reported, but there has been no technical route for achieving truly standard emission of the three wastes under the premise of zero pollutant discharge and maximum energy utilization. Therefore, practicality, harmlessness, resource coordination and comprehensive energy saving maximization are the research focuses of this patent. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a system for the coordinated treatment of three wastes in the production process of lincomycin, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a system for the coordinated treatment of three wastes in the production process of lincomycin, comprising a waste gas treatment subsystem, a waste water treatment subsystem, a waste residue treatment subsystem, and a terminal treatment subsystem;

[0008] The waste gas treatment subsystem includes two waste gas treatment routes, namely the waste gas adsorption and concentration treatment subsystem and the sewage aeration (aerobic section) treatment subsystem. The waste gas treatment subsystem provides fuel gas (concentrated gas) and auxiliary fuel gas (raw waste gas) for the terminal treatment subsystem.

[0009] The wastewater treatment subsystem includes pretreatment, hydrolysis and acidification, No. 1 intermediate settling tank, anaerobic section, No. 2 intermediate settling tank, aerobic section, sedimentation tank, mixed reaction tank, and final settling tank processes connected in sequence.

[0010] The waste residue treatment subsystem includes the fungus residue inactivation, fungus residue anaerobic digestion, fungus residue dehydration and screw conveyor connected in sequence. The waste residue treatment subsystem provides fuel (fungus residue) and gas (biogas) for the terminal treatment subsystem.

[0011] The terminal treatment subsystem includes solid waste / liquid incineration + waste heat boiler subsystem, steam turbine, and post-treatment device. The terminal treatment system provides steam for heating device of exhaust gas treatment subsystem, steam for pre-treatment heating of wastewater treatment subsystem, steam for inactivation and dehydration of waste residue treatment subsystem, and steam for fermentation tank disinfection of lincomycin production workshop.

[0012] Optionally, the waste gas adsorption and concentration treatment subsystem includes a waste gas pretreatment device, an adsorption and concentration device, a heating device, a 1# induced draft fan, and a 2# induced draft fan connected in sequence. The fermentation waste gas generated during the lincomycin fermentation process enters the pretreatment device. The pretreatment device includes but is not limited to alkali spraying, water spraying, variable temperature and humidity control, and high-efficiency dust removal. The pretreated waste gas meets the air intake conditions of the adsorption and concentration device.

[0013] The waste liquid generated by the spray tower of the pre-treatment device is collected in the wastewater treatment subsystem for treatment to avoid the discharge of new pollutants;

[0014] The adsorption and concentration device conducts adsorption and concentration treatment on the waste gas, and then the waste gas is discharged in compliance with the standards under the power transmission of the No. 1 induced draft fan. The heating device is used for the regeneration of the adsorption and concentration device. The heat source used by the heating device comes from the steam generated by the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem;

[0015] The exhaust gas after regeneration of the adsorption concentration device enters the terminal treatment subsystem under the transportation of the 2# induced draft fan. The high-concentration concentrated gas is used as fuel for the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem to ensure that the exhaust gas meets the emission standards;

[0018] For cleaning wastewater or biodegradable wastewater, it is directly introduced into the regulating tank;

[0019] For non-biodegradable or difficult-to-biodegrade wastewater, MVR technology is first used to concentrate the high-concentration wastewater, where the heat source used for concentration is the steam generated by the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem. After concentration, the high-concentration wastewater is transported to the terminal treatment subsystem as fuel for incineration in the power plant boiler, that is, the steam generated by the incineration of high-concentration wastewater through the boiler is used again for the concentration of high-concentration wastewater.

[0020] Optionally, the 1# intermediate sedimentation tank is used to separate sewage into pre-treated sludge and supernatant. The pre-treated sludge is dehydrated through a sludge thickening tank and a centrifuge, and the removed water is returned to the pre-treatment regulating tank as supernatant. The mud cake is sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem for fuel incineration.

[0021] Optionally, the anaerobic section uses an anaerobic biochemical method to treat the wastewater. The biogas produced in the anaerobic section is transported into a gas storage cabinet after desulfurization treatment, and then transported to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem for fuel incineration. The anaerobic sludge is dehydrated by the sludge concentration tank and dehydration equipment, and the removed water is returned to the 2# intermediate sedimentation tank as supernatant to merge with the anaerobic treatment drainage, and the mud cake is sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem for fuel incineration.

[0022] Optionally, the aeration source of the aerobic stage is fermentation waste gas, which enters the sewage in the form of small bubbles through diffusion, thereby increasing the dissolved oxygen content and causing some organic matter in the waste gas to be biochemically treated. The aeration exhaust is also sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem as fuel gas for incineration.

[0023] Optionally, the sludge discharged from the final settling tank and the sedimentation tank is concentrated and dehydrated, the supernatant is returned to the aerobic tank, and the mud cake is sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem as fuel incineration.

[0024] Optionally, the heat sources used by the mushroom residue inactivation system and the mushroom residue dehydration system are all from the steam generated by the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem; the mushroom residue enters the anaerobic digestion system first after inactivation, and the sterilized mushroom residue eliminates the inhibitory effects of the presence of antibiotics on anaerobic digestion, and the biogas produced by anaerobism is combined with the biogas produced by sewage anaerobism, and is used as fuel for incineration of the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem after desulfurization and other treatments; after dehydration, the screw conveyor is used to deliver it to the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem for fuel incineration.

[0025] Optionally, the solid waste / liquid incineration + waste heat boiler subsystem uses pulverized coal as the main fuel, followed by concentrated gas generated by the waste gas adsorption and concentration treatment subsystem, biogas generated by anaerobic digestion of the anaerobic section and bacterial residue of the wastewater treatment subsystem, aeration exhaust of the aerobic section of the wastewater treatment subsystem, mud cake after sludge concentration in the wastewater treatment subsystem, and high-concentration waste liquid after MVR concentration in the wastewater treatment subsystem as fuel gas or fuel, and the fermentation waste gas is burned as a combustion-supporting gas, and water vapor is generated after incineration to drive the steam turbine, and the steam turbine drives the generator to generate electricity;

[0026] The steam generated by the solid waste / liquid incineration + waste heat boiler subsystem not only enters the steam turbine for power generation, but also provides steam for heating devices in the exhaust gas treatment subsystem, steam for pretreatment heating in the wastewater treatment subsystem, steam for inactivation and dehydration in the waste residue treatment subsystem, and steam for fermentation tank disinfection in the lincomycin production workshop;

[0027] The exhaust gas from the solid waste / liquid incineration + waste heat boiler subsystem is treated by a post-treatment device, which includes but is not limited to one or more technologies such as dust removal, desulfurization, denitrification, spray washing, etc., to ensure that the exhaust gas meets the emission standards. The waste liquid generated during the post-treatment process is sent to the wastewater treatment subsystem for treatment.

[0028] The present invention provides a system for coordinating the three wastes in the production process of lincomycin, which has the following beneficial effects:

[0029] The three wastes coordinated treatment system in the lincomycin production process has strong system integrity and can achieve coordination between the subsystems;

[0030] The system takes the wastewater, waste gas and waste residue generated in the production process of lincomycin as the research objects, and forms a complete set of comprehensive treatment processes for the three wastes according to their respective treatment processes and process characteristics, involving waste gas treatment, wastewater treatment and waste residue treatment. On this basis, a terminal treatment subsystem is designed, and the subsystems can be interconnected and coordinated to ensure that the entire treatment system has the characteristics of harmlessness, resource utilization and energy saving.

[0031] The three wastes coordinated treatment system in the lincomycin production process has a strong adaptability in process flow and can operate stably and reliably under various working conditions. The design adopts multiple routes to treat the waste gas, and the treatment capacity of each route can be adjusted through valves according to actual air volume, concentration and other parameters, thereby reducing the high equipment investment cost caused by the use of a single route, such as the increase in treatment volume and the partial idleness of equipment due to the reduction in treatment volume.

[0032] The three wastes coordinated treatment system in the lincomycin production process has high energy utilization rate in each subsystem, no need for external fuel supplementation, and low operating cost;

[0033] Based on the three waste treatment subsystems, the system is designed to introduce solid waste / liquid incineration + waste heat boiler subsystem, and use the steam generated by the boiler to provide the heat required by the other three subsystems, such as the heat source required for heating during the analysis process of the waste gas adsorption device, the heat source required for the wastewater MVR process, and the heat source required for the waste residue inactivation and dehydration process. These heat sources all come from the terminal treatment subsystem. In addition, the disinfection of the lincomycin fermentation tank requires a large amount of high-temperature steam, which can also use the heat source provided by the terminal treatment subsystem. Therefore, the wastewater, waste gas, and waste residue treatment subsystems do not require external heat sources, with high energy utilization and reduced operating costs.

[0034] The three wastes coordinated treatment system in the lincomycin production process is environmentally friendly, has zero pollutant discharge, can achieve full compliance with emission standards, and can reduce the replenishment of fuel for the terminal treatment subsystem;

[0035] The waste gas treatment subsystem, waste liquid treatment subsystem and waste residue treatment subsystem may all be accompanied by the generation of pollutants in other states during operation. For these pollutants, some will enter the three waste treatment subsystems again, and some will enter the terminal treatment subsystem, such as waste gas concentrate, high-concentration waste liquid obtained by MVR treatment, mud cake obtained after sludge concentration and dehydration, and fungus residue after inactivation and dehydration. These components will enter the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment system as fuel gas (material) for incineration. On the one hand, it can reduce the supply and consumption of pulverized coal fuel, and on the other hand, it can ensure that the entire system has no pollutant discharge and can achieve full compliance with emission standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 This is a process flow chart of the three wastes coordinated treatment system in the lincomycin production process of the invention. DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1 The specific treatment process of the waste gas, waste water and waste residue generated in the production process of lincomycin is as follows:

[0039] (1) The whole process consists of four parts: waste gas treatment subsystem, wastewater treatment subsystem, waste residue treatment subsystem and terminal treatment subsystem;

[0040] (2) The waste gas generated during the production of lincomycin is divided into two routes: one of which is treated by an adsorption concentration system, and the valve is adjusted to ensure that the treatment system of this route operates at full capacity; the waste gas first enters the waste gas pretreatment device, which contains alkali spraying, water spraying, variable temperature and humidity control, and high-efficiency dust removal multi-stage pretreatment equipment to ensure that the pretreated waste gas meets the air intake conditions of the adsorption concentration device, and the waste liquid generated by the spraying device is collected in the wastewater treatment subsystem for treatment;

[0041] The waste gas treated by the pretreatment device enters the adsorption concentration device for treatment. The adsorption concentration device includes an adsorption zone, a desorption zone and a cooling zone. The adsorbent filled in the adsorption concentration device can be molecular sieve, activated carbon or macroporous resin. The adsorbent can be in the form of granules, honeycombs, wheels, etc.

[0042] After being adsorbed by the adsorption concentration device, the exhaust gas is discharged in compliance with the standards under the power transmission of the induced draft fan; the exhaust gas in the cooling area reaches the required temperature for analysis under the heating of the heating device and enters the analysis area of ​​the adsorption concentration device. After analysis, the exhaust gas is sent to the terminal treatment subsystem under the transmission of the 2# fan. The high-concentration concentrated gas is used as fuel for the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem for terminal harmless treatment. The heat source of the heating device comes from the steam generated by the boiler.

[0043] The second exhaust gas is used for aeration of the aerobic section in the wastewater treatment subsystem. According to the aeration demand of the aerobic section, the valve is adjusted to ensure that the air volume meets the aeration demand of the aerobic section.

[0044] The remaining waste gas from the third route is used as combustion-supporting gas to enter the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem for incineration treatment. The air volume of this waste gas is determined according to the demand of the other two routes;

[0045] (3) The wastewater generated during the production of lincomycin includes two categories: one is high-concentration wastewater containing difficult-to-biodegrade components, and the other is low-concentration wastewater such as tank cleaning wastewater. First, the high-concentration wastewater is introduced into the MVR device, and the wastewater is evaporated and concentrated through steam heat exchange, and finally a supernatant and a high-concentration waste liquid are obtained. The steam used in the MVR device comes from the solid waste / liquid incineration + waste heat boiler subsystem, and the high-concentration waste liquid is directly sent to the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem as fuel for incineration.

[0046] Low-concentration wastewater directly enters the regulating tank and is mixed with the supernatant obtained from the MVR device. Through the regulation of the regulating tank, the water quality of the wastewater is guaranteed to be stable when it enters the subsequent system, reducing the impact load on the subsequent treatment units; the wastewater regulated by the regulating tank enters the flotation tank, and the buoyancy of bubbles is used to remove impurities such as suspended matter in the wastewater;

[0047] Then the wastewater enters the hydrolysis and acidification tank, which is divided into two treatment processes: hydrolysis and acidification. The wastewater after hydrolysis and acidification enters the No. 1 intermediate sedimentation tank, and is separated in the No. 1 intermediate sedimentation tank to obtain pre-treated sludge and supernatant. The pre-treated sludge is dehydrated in the sludge concentration tank and centrifuge, and the dehydrated water is returned to the regulating tank as supernatant. The mud cake is sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem as fuel for incineration;

[0048] Subsequently, the supernatant from the 1# intermediate sedimentation tank is collected into the anaerobic tank for anaerobic biochemical treatment. The three processes of IC, ABR and UASB are used in parallel. The sewage after anaerobic treatment flows into the 2# intermediate sedimentation tank. The generated biogas is transported to the gas storage cabinet after desulfurization treatment, and then transported to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem for fuel incineration. The anaerobic sludge is dehydrated by the sludge concentration tank and dehydration equipment. The dehydrated water is returned to the 2# intermediate sedimentation tank as the supernatant and merged with the anaerobic treatment drainage. The mud cake enters the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem for fuel incineration.

[0049] After the 2# intermediate sedimentation tank is the aerobic stage. The sewage and the sludge returned from the sedimentation tank enter the aerobic tank together to form a mixed liquid. The aeration source is the waste gas in (2). Through diffusion and fermentation, the waste gas enters the sewage in the form of small bubbles, increasing the dissolved oxygen content while allowing some of the organic matter in the waste gas to be biochemically treated.

[0050] After the aerobic tank treatment, the sewage is treated in the sedimentation tank and then enters the mixed reaction tank. The color of the wastewater is reduced by adding coagulants, flocculants and other substances, and then enters the final sedimentation tank. It is treated in turn by coagulation sedimentation and inclined tube sedimentation tank to ensure the separation of mud and water, improve the clarity of drainage, and ensure that the drainage water quality meets the standards. The sludge discharged from the final sedimentation tank and sedimentation tank is concentrated and dehydrated, and the supernatant returns to the aerobic tank. The mud cake is sent to the terminal treatment subsystem solid waste / liquid incineration + waste heat boiler subsystem as fuel incineration;

[0051] (4) The waste residue generated during the production of lincomycin is first passed into a fungus residue inactivation device for sterilization treatment, and then the fungus residue is anaerobic digested. The residue after anaerobic digestion is then dehydrated. The heat source used in the sterilization and dehydration processes is the steam generated by the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem; the fungus residue after sterilization eliminates the inhibitory effect of the presence of antibiotics on anaerobic digestion, and the biogas generated by anaerobic digestion is combined with the biogas generated by sewage anaerobic digestion, and is used as fuel for incineration in the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem after desulfurization and other treatments; the waste residue after digestion treatment is stable in nature and easier to dehydrate; the fungus residue after dehydration is sent to the solid waste / liquid incineration + waste heat boiler subsystem of the terminal treatment subsystem by the screw conveyor as fuel for incineration;

[0052] (5) The solid waste / liquid incineration + waste heat boiler subsystem mainly uses pulverized coal as the main fuel. First, the coal is ground into pulverized coal and sprayed into the incineration device. At the same time, the exhaust gas described in 3) is used as a combustion-supporting gas to ensure that the pulverized coal is fully burned. The heat energy generated after incineration is used to generate water vapor through the waste heat boiler, and the water vapor drives the steam turbine, which drives the generator to generate electricity. In addition to using pulverized coal as fuel, the system also uses the concentrated gas generated by the waste gas adsorption and concentration treatment subsystem, the biogas generated by the anaerobic section of the wastewater treatment subsystem and the anaerobic digestion of the bacterial residue, the aeration exhaust of the aerobic section of the wastewater treatment subsystem, the mud cake after sludge concentration in the wastewater treatment subsystem, and the high-concentration waste liquid after MVR concentration in the wastewater treatment subsystem as fuel or gas for incineration.

[0053] In addition, the steam generated by the incineration device, in addition to entering the steam turbine, can also provide steam for the heating device of the exhaust gas treatment subsystem, provide steam for pre-treatment heating for the wastewater treatment subsystem, provide steam for inactivation and dehydration for the waste residue treatment subsystem, and provide steam for fermentation tank disinfection for the lincomycin production workshop;

[0054] (6) After incineration, the exhaust gas enters the post-treatment device, which includes dust removal, desulfurization, denitrification, and spray washing to ensure that the exhaust gas meets the emission requirements. The waste liquid generated during the post-treatment process is sent to the wastewater treatment subsystem for treatment.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
