Abstract
The invention discloses a pharmaceutical wastewater treatment technology. Pharmaceutical wastewater comprises high-concentration wastewater and low-concentration wastewater. The technology comprises the following steps: high-concentration pharmaceutical wastewater goes through a Fenton catalytic oxidation reaction tank for a Fenton reaction, and the reacted high-concentration pharmaceutical wastewater enters a high-efficiency precipitation tank; low-concentration pharmaceutical wastewater and water from the high-efficiency precipitation tank enter an equalizing tank, are lifted to a hydrolysis acidifying tank through a pump, and are acted by anaerobic microbes to remove organic matters and reduce suspensions in water, water from the hydrolysis acidifying tank flows into a CASS tank, and water in the CASS tank is discharged in a standard reaching manner; and sludge generated in the high-efficiency precipitation tank, sludge generated in the hydrolysis acidifying tank and sludge generated in the CASS tank are discharged to a sludge concentration tank, the obtained sludge concentrate is filter-pressed through a chamber filter press, and the obtained dry sludge is transported outward for treatment. The pharmaceutical wastewater treatment technology has the advantages of simple flow, large biochemical reaction moving force, strong impact resistance, small residual sludge amount and stable properties.
Description
Technical field
The present invention relates to the treatment process of a kind of drugmaker high density experiment waste water, specifically a kind of pharmaceutical wastewater treatment process.
Background technology
Pharmacy waste water belongs to one of more unmanageable high concentration organic sewage conventionally, and different because of medicament production, production technique is different and differ greatly, and is characterized in complicated component, and organic pollutant category is many, and concentration is high, COD content is high and fluctuation is large.Pharmaceutical factory normally adopts batch production, and product category changes greatly, causes the kind of waste water quality and pollutent to change greatly.
In the last few years, all kinds of medication chemistries of China and the fast development of healthcare products production, and a large amount of poisonous and harmful waste water serious harm people's that discharge in pharmacy procedure health, pharmacy corporation laboratory can produce all kinds of waste liquids in normal course of operation, many and the complicated component of these waste liquid kinds, accumulative total effect can not be ignored, and some produces secondary pollution in degraded, and directly discharge can produce and pollute water quality, environment.It is carried out categorised collection, by appropriate means, processes the responsibility that rear discharge is the experimenter of drugmaker.
Summary of the invention
The object of the present invention is to provide a kind of pharmaceutical wastewater treatment process.
Object of the present invention can be achieved through the following technical solutions:
A pharmaceutical wastewater treatment process, is characterized in that, comprises high-concentration waste water and low concentration wastewater, wherein:
(1) high density pharmacy waste water enters efficient sedimentation tank after Fenton's reaction occurs in Fenton catalytic oxidation pond;
(2) the same step of lower concentration pharmacy waste water (1) efficient sedimentation tank water outlet enters equalizing tank together, in equalizing tank, homogeneous is all measured, through pump, be promoted to hydrolysis acidification pool, by the effect of anaerobion, remove organism, reduce suspended substance in water, hydrolysis acidification pool water outlet flows into CASS pond, by the effect of aerobic microbiological, residual organic substances in waste water is converted into CO2 and H2O and removes the ammonia nitrogen in waste water; CASS pond water outlet qualified discharge;
(3) mud that efficient sedimentation tank, hydrolysis acidification pool and CASS pond produce enters sludge thickener, and through chamber-type press filter pressure filter, dry mud outward transport is disposed.
Beneficial effect of the present invention: pharmacy waste water technical process of the present invention is simple, and biochemical reaction impellent is large; Strong shock resistance; Surplus sludge volume is little, stable in properties.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
The waste water quality index that discharge in table 1 Wei Mou drugmaker laboratory:
| Waste water type | pH | COD | BOD | NH3-N | SS |
| High-concentration waste water | — | ≤350000 | ≤150000 | — | ≤2000 |
| Low concentration wastewater | 6-9 | ≤1000 | ≤400 | ≤16 | ≤190 |
Treatment process of the present invention is: first high density experiment waste water remove most organic after Fenton's reaction occurs in Fenton catalytic oxidation pond; After enter efficient sedimentation tank and remove suspended substance and organism in waste water; Enter afterwards equalizing tank together with low concentration wastewater, the even water yield in equalizing tank; Through pump, be promoted to hydrolysis acidification pool again, by the effect of anaerobion, remove partial organic substances in waste water, improve the biochemical of waste water, reduce the suspended substance in waste water; Hydrolysis acidification pool water outlet flows into CASS pond, by the effect of aerobic microbiological, residual organic substances in waste water is converted into CO
2and H
2o also removes the ammonia nitrogen in waste water; CASS pond water outlet qualified discharge.
The excess sludge that efficient sedimentation tank, hydrolysis acidification pool and CASS pond produce enters sludge thickener, and through chamber-type press filter pressure filter, dry mud outward transport is disposed.
Table 2 is the effluent quality after the present invention processes:
| Control project | pH | COD | BOD | NH3-N | SS |
| Emission standard | 6-9 | ≤330 | ≤160 | ≤20 | ≤200 |
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.
