Abstract
The invention discloses a Chinese patent medicine production wastewater treatment technology, and belongs to the technical field of wastewater treatment. The technology comprises the steps of (1) pretreatment, (2) coagulation precipitation treatment, (3) anaerobic treatment, (4) aerobic treatment, (5) filtering treatment, and (6) sludge treatment. Chinese patent medicine wastewater undergoes pretreatment, coagulation precipitation, anaerobic treatment, aerobic treatment and the like, so the chemical oxygen demand (COD), the biochemical oxygen demand (BOD), the concentration of solid suspension (SS) and the content of ammonia nitrogen (NH3-N) in the wastewater are greatly reduced, and the influences on the environment are reduced.
Description
Technical field
The present invention relates to the processing of pharmacy field waste water, the treatment process of especially a kind of capsule, tablet, granule Chinese patent medicine factory effluent.
Background technology
Chinese patent medicine waste water of pharmaceutical industry is the high concentrated organic wastewater that a class contains hard-degraded substance and bio-toxicity material, and domestic Chinese patent medicine waste water of pharmaceutical industry quantity discharged is large, and water pollution is serious.The feature of its waste water is that complicated component, organic content are high, toxicity is large, colourity is dark and saltiness is high, and particularly biochemical is very poor, and intermittently discharged, belongs to unmanageable trade effluent.Along with the development of China's medicine industry, Chinese patent medicine pharmacy waste water becomes one of important source of pollution gradually, and how processing such waste water is a difficult problem of current environment protection.
The processing of herbal pharmaceutical industry waste water has become problem demanding prompt solution, so the effective pharmacy waste water treatment technology of exploiting economy has important theory significance and realistic meaning.Chinese patent medicine wastewater processing technology is at home and abroad studied seldom.
Summary of the invention
The object of the present invention is to provide a kind for the treatment of process of Chinese patent medicine factory effluent.
Object of the present invention can be achieved through the following technical solutions:
A treatment process for Chinese patent medicine factory effluent, is characterized in that, comprises the following steps:
(1) pre-treatment: high-concentration waste water is removed large impurity through grille well, after enter preliminary sedimentation tank, remove after large suspended substance from flowing to equalizing tank even water quality in equalizing tank;
(2) coagulating sedimentation is processed: equalizing tank water outlet is promoted to coagulative precipitation tank I through pump, the water outlet of coagulative precipitation tank I is from flowing to iron-carbon micro-electrolysis reactor, larger molecular organics is converted into small organic molecule, the water outlet of iron-carbon micro-electrolysis reactor flow to coagulative precipitation tank II, removes suspended substance, organism;
(3) anaerobic treatment: the water outlet of coagulative precipitation tank II is mixed into hydrolysis acidification pool with low concentration wastewater, and hydrolysis acidification pool water outlet is promoted to UASB anaerobic reactor through pump, the water outlet of UASB anaerobic reactor enters backflow pond;
(4) aerobic treatment: the water outlet of backflow pond flow to SBR pond, by the effect of aerobic microbiological, removes organism and ammonia nitrogen, and the water outlet of SBR pond flow to blowoff basin;
(5) filtration treatment: blowoff basin water outlet after medium filter filters by standardization discharge outlet qualified discharge;
(6) sludge treatment: the mud that preliminary sedimentation tank, hydrolysis acidification pool, UASB anaerobic reactor, SBR pond, coagulative precipitation tank I, coagulative precipitation tank II produce enters sludge thickener, through folded spiral shell pressure filter press filtration, dry mud outward transport is disposed.
Beneficial effect of the present invention: the present invention combines Chinese patent medicine waste water through steps such as pre-treatment, coagulating sedimentation, anaerobic treatment and aerobic treatment, significantly reduce the chemical oxygen demand cod in waste water, biochemical requirement BOD, solid suspension substrate concentration SS, ammonia-nitrogen content NH3-N, reduce the impact on environment.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
Table 1 is the waste water quality index of certain wafer, tablet, the discharge of granule Chinese patent medicine enterprise:
| Waste water type | pH | COD | BOD | NH3-N | SS |
| High-concentration waste water | — | ≤16000 | ≤4500 | ≤50 | ≤1500 |
| Low concentration wastewater | 6-9 | ≤500 | ≤250 | ≤30 | ≤250 |
Treatment process of the present invention is: first high-concentration waste water removes large impurity through grille well, after enter preliminary sedimentation tank, remove after most suspended substances from flowing to equalizing tank even water quality in equalizing tank; Through pump, be promoted to coagulative precipitation tank I again, control into iron-carbon micro-electrolysis suspended substance; The water outlet of coagulative precipitation tank I flow to iron-carbon micro-electrolysis, and larger molecular organics is converted into small organic molecule, improves the biodegradability of waste water; Iron-carbon micro-electrolysis water outlet flow to coagulative precipitation tank II, removes suspended substance, organism and regulates wastewater pH; The water outlet of coagulative precipitation tank II is mixed into hydrolysis acidification pool with low concentration wastewater, further reduces the biodegradability of organism and raising waste water; Hydrolysis acidification pool water outlet is promoted to UASB anaerobic reactor through pump, by anaerobic reaction, removes most organic; The water outlet of UASB anaerobic reactor enters backflow pond, then flow to SBR pond, by aerobic microbiological effect, removes residual organic substances and ammonia nitrogen; SBR water outlet flow to blowoff basin, then after more medium filter filters by standardization discharge outlet qualified discharge.
The excess sludge that preliminary sedimentation tank, hydrolysis acidification pool, UASB, SBR pond, coagulative precipitation tank I, coagulative precipitation tank II produce enters sludge thickener, and through folded spiral shell pressure filter press filtration, dry mud outward transport is disposed.
Table 2 is the effluent qualities after the present invention processes:
| Control project | pH | COD | BOD | NH3-N |
| Emission standard | 6-9 | ≤100 | ≤20 | ≤8 |
Table 3 is each section of effluent quality index of the present invention (unit is all with mg/L)
Above content is only to technique example of the present invention and explanation; affiliated those skilled in the art make various modifications to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the technique of invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
