Description
Technical field
The utility model relates to field of waste water treatment, specifically a kind of waste water treatment unit in early stage, especially processes the waste water treatment unit in early stage of the waste water produced in 2-chlorine apellagrin and 2-thiophene ethanol production process.
Background technology
2-chlorine apellagrin has another name called 2-chlorine Nicotinicum Acidum, has special physiologically active, is a kind of important medicine and pesticide intermediate, can be used for producing agricultural herbicide, sterilant, medicinal antibiosis agent etc.And the derivative of 2-chlorine apellagrin is numerous, its range of application relates to the frontiers such as fine chemical product chain and Organic electro-synthesis.2-chlorine apellagrin take nicotinonitrile as starting raw material, produces N-oxide compound, re-uses POCl3 and carry out nucleophilic substitution reaction as chlorizating agent, be finally hydrolyzed in the basic conditions, crystallization obtains 2-chlorine apellagrin through hydrogen peroxide oxidation.2-chlorine apellagrin is produced waste discharge and is mainly production technique waste water and workshop flushing waste water.Factory effluent comprises oxidation centrifuge waste water, chlorination centrifuge waste water and hydrolysis crystallization centrifuge waste water.Particular case is as follows: being 1. oxidized centrifuge waste water is strongly-acid high-COD waste water, this reaction molar yield about 94%, therefore containing a large amount of unreacted nicotinonitrile in waste water.2. chlorination centrifuge waste water is high phosphorus waste water, has phosphate radical to produce during non-chlorination reaction, superfluous POCl
3be hydrolyzed to phosphoric acid during elutriation, chlorination reaction molar yield about 93%, therefore this strand of waste water is high COD, high phosphorus waste water.Because this phosphorus in waste water content is high, feeding lime generates calcium phosphate precipitation, sells comprehensive utilization after centrifugation outside solid, and form a large amount of flcos, flco adsorbed polymer organism during precipitation, the waste water COD concentration after centrifugal reduces greatly simultaneously.3. hydrolysis reaction uses a large amount of sheet alkali, and molar yield about 90%, therefore this strand of waste water is high COD, high-salt wastewater.Add up according to existing practical condition, this product wastewater flow rate is about 32m
3/ d, COD concentration is about 25000mg/L.Low concentration wastewater establishes 30m
3/ d, COD concentration is about 550mg/L.
2-thiophene ethanol can be used for the synthesis of multi-medicament, is the key intermediate preparing thiophene pyridine compounds and their, is also the bulk drug of the multiple cardiovascular relevant with thrombocyte and thrombus disease and anti-inflammatory drug.2-thiophene ethanol take thiophene as starting material, through bromine bromination, reacts generate Grignard reagent in tetrahydrofuran (THF) (THF) and MAGNESIUM METAL, Grignard reagent and oxyethane effect, is hydrolyzed and obtains 2-thiophene ethanol.The waste water produced in 2-thiophene ethanol production process mainly comprises the following aspects: explained hereafter waste water, equipment washing waste water, ground cleaning waste water, waste gas washes, boiler wastewater, recirculated water waste water, early-stage rainwater and sanitary sewage.Wherein production technique waste water, equipment washing waste water and water-ring pump waste water COD concentration are higher, merge into density wastewater, and other ground cleaning waste water, waste gas washes, boiler wastewater, recirculated water waste water, early-stage rainwater and sanitary sewage merge into rare waste water.
The waste water produced in 2-chlorine apellagrin and 2-thiophene ethanol production process is high salt, high ammonia nitrogen, high phosphorus and the waste water of high COD, and directly discharge is huge to the pollution of environment, destroys ecotope, is unfavorable for environmental protection and Sustainable development.
Utility model content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of waste water treatment unit in early stage, solves the undesirable problem of current waste water treatment effect in early stage, meets the demand of enterprise's production of environmental protection more.
The utility model solves the technical scheme that its technical problem adopts: this waste water treatment unit in early stage, comprise grating tank, grating tank is connected with water collecting basin, lift pump is provided with in water collecting basin, water collecting basin is connected to comprehensive adjustment pond by lift pump, comprehensive adjustment pond is connected with preliminary sedimentation tank, is connected with solarization air cap in preliminary sedimentation tank, and preliminary sedimentation tank is connected with intake pump by pipeline.After arranging like this, special contamination factor waste water enters comprehensive adjustment pond again by after pretreatment workshop pre-treatment after collecting separately.Because production process is intermittent type, waste discharge water quality and quantity is many in ununiformity, carries out sufficient homogeneous through comprehensive adjustment pond to water quality and quantity.Comprehensive adjustment pond regulates about pH3.5 to density wastewater, regulates pH to be 7.5 ~ 8 to rare waste water.Fenton oxidation agent is added, H in comprehensive adjustment pond
2o
2at F
e 2+the hydroxyl radical free radical (OH) with high reaction activity is generated under katalysis, OH not only oxidation capacity is strong, and speed of response is fast, adding Fenton oxidation agent main purpose is not for directly removing COD, but toxic organic compound is detoxified, open loop chain rupture is carried out to the organism of difficult degradation, alleviates the load of subsequent purification technique.Density wastewater after oxidation is promoted to preliminary sedimentation tank, adds a small amount of flocculation agent, by the suspended solid in gravitational settling separation removal waste water and colloidal organic matter, to alleviate subsequent biological treatment load.For preventing precipitating too much suspended substance, therefore increase solarization air cap at the bottom of preliminary sedimentation tank, solarization air cap is communicated with low-pressure steam, prevents precipitation by air agitation.Mud pumps into sludge thickener.Preliminary sedimentation tank water outlet pumps into compound oxygen compatibility pool again.
The second Root's blower is connected with by pipeline in comprehensive adjustment pond.Air is passed in comprehensive adjustment pond by the second Root's blower, for the oxidizing reaction in comprehensive adjustment pond is given security, and speed up processing.
Be provided with the monitoring sensor of pH value and the sensor of monitor temperature in preliminary sedimentation tank, in preliminary sedimentation tank, water collecting basin, be provided with the sensor of monitoring liquid level.The sensor of monitor temperature and the sensor of monitoring liquid level make supervisory system temperature and liquid level position be achieved, and significantly improve the security of system cloud gray model, avoid the generation of industrial accident.
The effect that the utility model is useful is: of the present utility model reasonable in design, by density wastewater and rare waste water treatment process are combined, realize the process in early stage to the waste water in art production process and oxide treatment, condition is provided for sequential hydrolysis is refining, and alleviate the purification burden of subsequent purification system, make decontamination effect improving obvious, be suitable for promoting.
