Pharmaceutical sewage treatment system

With the development of my country’s medical industry, the pharmaceutical industry has also developed rapidly. However, in the process of producing pharmaceuticals, a large amount of drug residues and waste water will be produced.

The discharged sewage is also one of the sources of industrial sewage, and pharmaceutical sewage mainly includes four types, which are high in concentration, deep in color, difficult to degrade, and high in toxicity (with strong corrosive or chemical properties).

Most manufacturers discharge directly without treatment, causing great pollution to the environment. It is even reported that some sewage plants use sprinklers to discharge sewage into the sewers in points, causing great harm.

And now the state has put forward new requirements for environmental protection, so that pharmaceutical companies have to pay attention to sewage discharge standards.

The current pharmaceutical sewage is different from the traditional sewage. During the production process, a large amount of waste residue will be discharged together with the sewage, which can easily lead to the blockage of the sewage treatment system.

Moreover, the sewage treatment system lacks a method for treating sludge in sewage, resulting in substandard discharge.

The purpose of the present invention is to provide a pharmaceutical sewage treatment system to solve the problems of easy blockage and poor sewage treatment effect proposed in the above-mentioned background art.

A first settling chamber is included, a sealing cylinder is fixedly connected to the inside of the first settling chamber, and a piston is movably connected to the interior of the sealing cylinder.

One side of the piston is fixedly connected with a push rod one, one end of the push rod one is fixedly connected with a handrail, and the other end of the piston is fixedly connected with a push rod two.

One end of the second push rod is fixedly connected with a push plate, one side of the first settling chamber is fixedly connected with the water pump 1 through a sewage pipe, and the output end of the water pump 1 is fixedly connected with the first reaction chamber.

One side of the first reaction chamber is movably connected to the second reaction chamber through a water outlet pipe 1, and a motor is fixedly connected to the upper surface of the second reaction chamber.

The output end of the motor is sleeved with a rotating shaft, the outer surface of the rotating shaft is sleeved with a stirring blade, and one side of the second reaction chamber is fixedly connected with a second settling chamber.

The lower surface of the second settling chamber is fixedly connected with the sediment pump through the sewage pipe, and the output end of the sediment pump is fixedly connected with the sludge drying tank.

In a further embodiment, a water inlet pipe is fixedly connected to the upper surface of the first settling chamber, and a coarse slag discharge pipe is fixedly connected to one side of the first settling chamber.

In a further embodiment, a feeding port 1 is fixedly connected to the upper surface of the first reaction chamber, and a water pump 2 is fixedly connected to the lower surface of the first reaction chamber.

The input end of the second water pump is fixedly connected with the second settling chamber.

In a further embodiment, an activated carbon adsorption layer is fixedly connected to the inside of the second settling chamber, a feeding pipe is fixedly connected to one side of the second settling chamber, and a feeding port 2 is fixedly connected to one end of the feeding pipe.

In a further embodiment, a second water outlet pipe is fixedly connected to the lower surface of the second settling chamber, and a water valve is provided on one side of the second water outlet pipe.

In a further embodiment, a partition plate is fixedly connected to the inside of the sludge drying box, and a heating wire is fixedly connected to the lower surface of the partition plate.

Compared with the prior art, the beneficial effects of the present utility model are:

In the utility model, the first settling chamber is provided, and the filter screen is fixedly connected inside the first settling chamber, so that the coarse slag in the sewage can be screened out and pushed through the handrail.

Using the first push rod to push the piston and the second push rod to make the push plate discharge the residue on the filter screen through the coarse slag discharge pipe to prevent the water pipe below from being blocked. A first reaction chamber and a second reaction chamber are provided.

The reaction medicine is added therein to separate and settle the toxic substances in the sewage and the water, so as to reduce the toxicity in the sewage. The rotating shaft and the stirring blade are driven by a motor arranged in the second reaction chamber.

The internal sewage is fully reacted with the drug to settle and then separate and enter the second settling chamber, and the harmful organic matter in the sewage can be adsorbed by the activated carbon adsorption layer in the second settling chamber.

Adding drugs through the feeding port 2 can further improve the treatment effect of sewage, and the purified sewage will enter the first reaction chamber again through the second water pump for secondary reaction and purification.

The effect of sewage treatment is ensured. By setting a sludge drying box, the settled sludge is passed into it through a sediment pump, and the sludge is dried and centrally treated by a heating wire so that the effect of sewage treatment is better.
