Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams illustrating only the basic structure of the invention in a schematic manner, and thus show only the constitution related to the invention.
Fig. 1 is a schematic diagram of the framework of the present invention.
As shown in the attached figure 1, a biomembrane reaction type pharmaceutical wastewater treatment method comprises the following steps:
a) the pharmaceutical wastewater enters an adjusting tank for stirring and pre-aeration treatment, and the treated wastewater is sent into a coagulating sedimentation tank;
b) a flocculating agent is added into the coagulating sedimentation tank, after suspended matters in the wastewater are removed by the coagulating sedimentation tank, the wastewater enters the sequencing batch biofilm reactor, and sludge discharged from the coagulating sedimentation tank is transported outside for treatment;
c) after microorganisms in the wastewater are removed by the sequencing batch biofilm reactor, the wastewater is sent into a filter tank for ultrasonic disinfection, and water which reaches the discharge standard is obtained after disinfection.
The flocculating agent is polyacrylamide.
The coagulating sedimentation tank is one of sedimentation tanks in water supply and drainage. The coagulation process is the most basic and very important treatment process in the treatment of industrial water and domestic sewage, and by adding some medicaments (generally called coagulant and coagulant aid) into water, particles which are difficult to precipitate in the water can be polymerized with each other to form colloid, and then are combined with impurities in the water body to form larger floccules. The flocculating constituent has strong adsorption capacity, can adsorb suspended matters, and can adsorb partial bacteria and soluble substances. The flocs sink down by increasing their volume through adsorption.
A Sequencing Batch Biofilm Reactor (Sequencing Biofilm Batch Reactor), also known as a membrane SBR (BABR), is a new biological sewage treatment process which is researched and applied at home and abroad. The sequencing batch biofilm reactor is a novel composite biofilm reactor developed by filling different fillers (such as fiber fillers, activated carbon, ceramsite and the like) in an SBR reactor, and the intervention of the fillers provides a more favorable living environment for microorganisms. The microorganisms form a complex ecosystem consisting of a plurality of nutrition levels such as bacteria, fungi, algae, protozoa, metazoan and the like in the longitudinal direction, and form a suspended aerobic type, attached facultative type and attached anaerobic type microorganism system with various different activities, breathing types and nutrition types in the transverse direction along the direction of water flowing to the carrier, thereby greatly improving the processing capacity and stability of the reactor, and the advantages of stable reaction process, more and complex biomass, less residual sludge, less power consumption and small occupied area of the sequencing batch biofilm reactor are achieved.
The sterilization and disinfection mechanism of the ultrasonic wave is that the ultrasonic wave can perform ultrasonic cavitation in liquid to instantly generate hundreds of millions of cavitation micro bubbles, a plurality of cavitation bubbles are instantly generated and instantly exploded, meanwhile, the temperature of the liquid is continuously increased along with high temperature and high pressure, a hand is stretched into the liquid to feel pinprick, the cavitation generates strong mechanical shearing action, and the cell walls of microorganisms can be broken, so that the cell contents overflow out of the cell walls, and thus, certain components in the cells, such as DNA, RNA, amino acid, alkaloid, protein and the like can be extracted. The adoption of ultrasonic wave sterilization avoids the generation of harmful byproducts and the irreversible influence on human bodies and the environment. In addition, the characteristic of large water volume of the papermaking wastewater is that the cost of the medicament is obviously increased if chlorine adding disinfection is continuously adopted, and the ultrasonic disinfection mode does not need to add any substance into water, so that the cost is superior to that of the chlorine adding disinfection firstly, and other substances do not need to be added, so that the water quality is not affected by adopting the ultrasonic disinfection.
In light of the foregoing description of preferred embodiments according to the invention, many modifications and variations can be made by the worker skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
