Abstract
The invention provides a pretreatment method of refinery waste water. Waste residues for producing alkali are taken as a treatment agent and mixed with the refinery waste water to form a clarifying solution, and then the clarifying solution is taken to finish the pretreatment, thus the aims for reducing the chroma of waste water and the values of NH3-N and COD are achieved. The pretreatment method takes the waste residues for producing alkali as the treatment agent and has the advantages of low cost, full utilization of waste resources, proper and wide range of waste water and the like.
Description
Technical field
The present invention relates to a kind of pretreatment method of refinery waste water.
Background technology
The a large amount of waste water of normal generation in the oil refining production process, tool is added up one ton of crude oil of every refining and is wanted 3.4 tons of waste water of average generation, and the refinery water complicated component is the composite waste of multiple pollutents such as a kind of sulfur-bearing, oily phenol, organonitrogen, benzene, paraffin, high molecular polymer; The Pollutant levels height, COD reaches 1500-2000mg/L, NH
3-N reaches 200-400mg/L; Major part is a hard-degraded substance in the waste water, and big to microorganism toxicity, biodegradability is poor, thereby intractability is very big, adopts at present usually materialization and the biochemistry technologies such as treatment process, for example oil removal, flotation, A/O, catalytic oxidation, precipitation that combine.Because refinery water complicated component, Pollutant levels are big, strengthened and handled load, make refinery water handle the disposable input height of ubiquity, complex process, poor stability, processing cost height, effluent quality and be difficult to stably reaching standard.
Summary of the invention
The invention discloses a kind of pretreatment method of refinery waste water, with the soda-manufacturing waste residue is treatment agent, can reduce water inlet Pollutant levels and processing load that refinery water is handled, reach the purpose that reduces chroma in waste water, NH3-N and COD value, reduce the processing cost of refinery water, make the easier stably reaching standard of effluent quality.
Soda-manufacturing waste residue is the waste that effluxes in the soda ash production process, is a kind of by elementary composition colloidal materials such as silicon, magnesium, calcium, oxygen, carbon, to heavy metal, organism, NH
3-N etc. have very strong adsorptivity.
The present invention adopts following technical scheme:
Treatment agent is selected soda-manufacturing waste residue for use, and soda-manufacturing waste residue is contacted with the refinery water thorough mixing, and supernatant liquor is discharged to finish the refinery water pre-treatment in the clarification back.
As preferred technical scheme, be treatment agent with the soda-manufacturing waste residue, earlier with the soda-manufacturing waste residue wet-milling, be 1-5 in waste residue and waste water weight ratio then: 100 ratio thorough mixing stirs, and clarification back supernatant liquor is discharged, and finishes the refinery water pre-treatment.
The present invention is owing to be treatment agent with the waste soda-manufacturing waste residue, and cheap and easy to get, treatment process is simple, can make full use of waste material, reduces refinery water and handles load and cost, utilizes method of the present invention, and the COD clearance of refinery water is 50-60%; NH
3-N clearance is 67-77%; The supernatant liquor water white transparency, percent of decolourization reaches 85-90%.The present invention can also be used for the pre-treatment of other similar waste water.
Embodiment
The present invention is further illustrated below by embodiment.
Embodiment 1 gets 10 kilograms of refinery waters, puts into the container that band stirs, and this waste water is light brown band stink, and COD is 1800mg/L, NH
3-N is 300mg/L, adds soda-manufacturing waste residue 100 grams of wet-milling in container, and normal temperature stirred 40-60 minute down, clarification, and supernatant C OD is 900mg/L after measured, clearance is 50%; NH
3-N is 100mg/L, and clearance is 67%; Supernatant liquor water white transparency, percent of decolourization are 85%.
Embodiment 2 gets 10 kilograms of refinery waters, puts into the container that band stirs, and this waste water is light brown band stink, and COD is 1780mg/L, NH
3-N is 320mg/L, adds soda-manufacturing waste residue 250 grams of wet-milling in container, and normal temperature stirred 40-60 minute down, clarification, and supernatant C OD is 890mg/L after measured, clearance is 50%; NH
3-N is 96mg/L, and clearance is 70%; Supernatant liquor water white transparency, percent of decolourization are 85%.
Embodiment 3 gets 10 kilograms of refinery waters, puts into the container that band stirs, and this waste water is light brown band stink, and COD is 1750mg/L, NH
3-N is 350mg/L, adds soda-manufacturing waste residue 500 grams of wet-milling in container, and normal temperature stirred 60-80 minute down, clarification, and supernatant C OD is 700mg/L after measured, clearance is 60%; NH
3-N is 80mg/L, and clearance is 77%; The supernatant liquor water white transparency, percent of decolourization reaches 90%.
