Abstract
The invention relates to a method for treating pharmaceutical wastewater, belonging to the technical field of treatment of wastewater, in particular to a method for treating pharmaceutical wastewater. The invention provides the method for treating the pharmaceutical wastewater, which has high treatment efficiency and good treatment effect and can directly discharge pharmaceutical wastewater. The method mainly comprises the following steps of: (1) leading wastewater to flow into a grating to retain a suspending pollutant in large volume; (2) leading discharge water to flow into an adjusting pool, adjusting the quality and water yield of the wastewater to be beneficial to the effective running of a following treatment unit; (3) leading the discharge water to flow into a hydrolysis acidizing pool, and improving the biochemical performance of the wastewater to be beneficial to the subsequent aerobic treatment; and (4) leading the discharge water of the hydrolysis acidizing pool to flow into a membrane biological reaction pool and carrying out aerobic treatment on the organic pollutant for producing the wastewater.
Description
Technical field
The invention belongs to technical field of waste water processing, particularly a kind of treatment process of pharmaceutical wastewater.
Background technology
Since 20th century, developing rapidly of medicine industry brought leap to human civilization, and meanwhile, the waste water that is emitted in its production process also increasingly sharpens to the pollution of environment, has brought serious threat to human health.It is reported that pharmaceutical wastewater complicated component, concentration and salinity height, colourity and toxicity are big, often contain miscellaneous organic pollution materials, the material that much belongs to bio-refractory is arranged in these materials, can in considerable time, retain in the environment.Particularly to great " three cause " (carcinogenic, teratogenesis, the mutagenesis) organic pollutant of human health risk, even human health that still can serious harm when concentration is lower than the 10-9 level in water body adopts traditional treatment process to be difficult to qualified discharge.
The processing of pharmaceutical wastewater, method commonly used have traditional aerobic biochemical treatment process, but there is following shortcoming: the pollutant load that can directly bear is less, and the activated sludge concentration fluctuation is bigger, and volumetric loading is lower.Because medical factory effluent is an intermittent discharge, its water yield and variation water quality scope are bigger, and the sludge bulking meeting that causes because of factors such as load variations causes fatal influence to the entire treatment system.Therefore, the traditional technology treatment facility is difficult to satisfy the degree of depth requirement of medical production wastewater treatment.
Summary of the invention
The invention provides the treatment process of a kind of processing efficiency height, treatment effect is good, water outlet can directly be discharged pharmaceutical wastewater.
The present invention is achieved by the following technical solutions: a kind of treatment process of pharmaceutical wastewater comprises the steps:
(1) waste water is introduced into grid, holds back the large volume suspended contaminant;
(2) water outlet enters equalizing tank, regulates the water quality and quantity of waste water, helps the unitary effective operation of subsequent disposal;
(3) water outlet enters hydrolysis acidification pool again, improves the biodegradability of waste water, helps follow-up aerobic treatment;
(4) water outlet of hydrolysis acidification pool enters the membrane biological reaction pond, and the organic pollutant of factory effluent is carried out aerobic treatment;
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
(1) waste water is introduced into grid, and the inclination angle is 60 degree, and interval of grid strip is 15mm, and when waste water flow through, the bulk pollutent that is suspended state was held back by grizzly bar and removed from waste water.Grid can reduce the suspended substance protection subsequent disposal facility in the sewage;
(2) water outlet enters equalizing tank, makes the water quality and the water yield keep relative stablizing, and guarantees that the subsequent disposal system is stable;
(3) water outlet enters hydrolysis acidification pool again, add sodium hydroxide adjusting pH value before entering hydrolysis acidification pool, in hydrolysis acidification pool, macromole organic pollutant in the sewage resolves into micromolecular organism under the effect of acidication bacterium, improve the biodegradability of waste water, help follow-up aerobic treatment;
(4) water outlet of hydrolysis acidification pool enters the membrane biological reaction pond, and the membrane biological reaction pond mainly is made up of oil body, hollow membrane assembly, water-distributing device and quick-fried device of air, and the organic pollutant of factory effluent is carried out aerobic treatment, adopts blast aeration.
Sewage after above-mentioned art breading can reach the discharging standards discharging.

Claims (2)
1. the treatment process of a pharmaceutical wastewater, may further comprise the steps: (1) waste water is introduced into grid, holds back the large volume suspended contaminant; (2) water outlet enters equalizing tank, regulates the water quality and quantity of waste water, helps the unitary effective operation of subsequent disposal; (3) water outlet enters hydrolysis acidification pool again, improves the biodegradability of waste water, helps follow-up aerobic treatment; (4) water outlet of hydrolysis acidification pool enters the membrane biological reaction pond, and the organic pollutant of factory effluent is carried out aerobic treatment.
2. the treatment process of a kind of pharmaceutical wastewater according to claim 1 is characterized in that: described grid inclination angle is 60 degree, and interval of grid strip is 15mm.
