Technical description of school laboratory wastewater integrated equipment

Author: Pu film Source: Laboratory sewage treatment equipment Date: 2019-08-31 Category: News

With the development of science and technology in China, the demand for laboratories is increasing, especially in the past ten years, the number of various types of laboratories has been increasing. From the perspective of the distribution of laboratories, it is mainly concentrated in industries such as middle and higher education institutions, scientific research institutes, medical institutions, biopharmaceuticals, disease control, environmental supervision, product quality inspection, drug inspection, blood stations, animal husbandry, hospitals, and enterprises. The laboratory wastewater discharge is not large, it is a relatively independent institution, and the area is scattered, and its pollution is easy to be ignored.


Technical description of school laboratory wastewater integrated equipment


学校实验室废水


Laboratory wastewater treatment equipment adopts pretreatment, high-efficiency acid-base neutralization reaction, enhanced flocculation capture, high-precision filtration and adsorption, and catalytic oxidation and disinfection processes to treat laboratory wastewater. The laboratory organic wastewater treatment method can learn from the treatment of other organic wastewater. For laboratory wastewater with high concentration of organic matter, strong toxicity, and unstable water quality, the biological treatment method is not effective, and the physical and chemical method has obvious advantages in the treatment of such wastewater.


Organic wastewater treatment methods include physical and chemical treatment methods and biological treatment methods. The physicochemical treatment method is a method that uses the physical and chemical action and its principle to convert the pollutant components in the waste water into harmless substances and purify the waste water.


Composition of school laboratory wastewater integrated equipment


1.Adjustment tank


Due to the high level of the incoming water, it cannot directly flow into the buried domestic sewage treatment equipment, and a water collection regulating tank is added before the integrated biochemical equipment. There are two submersible lift pumps in the water collection lifting pond, and the school laboratory sewage treatment device lifts the wastewater in the water collection lifting pond into the sewage treatment equipment. The regulating tank plays the role of homogenizing water quality and quantity at the same time.


B. Grille


The wastewater from the adjustment tank is pumped into the grid of the sewage treatment equipment by a lift pump, and the grid intercepts various floating substances contained in the sewage. To prevent clogging of subsequent pumps or treatment equipment; to avoid sedimentation in subsequent ponds and increase the number of maintenance. Grid specifications: 1000mm * 500mm (length * width), grid gap 6mm.


C. Biological contact oxidation tank (including primary oxygen tank and secondary oxygen tank)


In the biological contact oxidation tank, the blower and microporous aerator are used to continuously supply oxygen to the wastewater, and aerobic microorganisms are used to oxidize organic matter, which greatly reduces the COD and BOD in the wastewater and reaches the discharge standard.


D. Sedimentation tank


The biochemical sewage enters the sedimentation tank, and the suspended matter in the sewage is partially settled at the bottom of the pond, and the clarified sewage flows out from the overflow weir at the other end of the sedimentation tank. The sludge accumulated in the sedimentation tank is returned to the contact oxidation tank by a sludge pump. The sedimentation tank adopts the form of inclined plate sedimentation tank to increase the precipitation effect and ensure the quality of the effluent water.

E. Sludge pond


The sludge at the bottom of the sedimentation tank enters the sludge tank under the effect of gravity. The sludge in the sludge tank is regularly returned by the sludge pump. The biological contact oxidation tank is used to ensure the sludge volume of the biochemical tank and aerobic digestion. Remove part of the sludge.


F. Water disinfection tank


The disinfection tank receives overflow water from the sedimentation tank. The sodium hypochlorite solution is added to the disinfection tank of the sewage treatment device of the school laboratory to kill the toxic and harmful microorganisms such as Escherichia coli remaining in the water after treatment to ensure the safety of the effluent.


G. Disinfection dosing device


The disinfection dosing device is composed of a dosing barrel and a dosing pump. The dosing barrel is filled with a diluted sodium hypochlorite solution with a concentration of about 10%. The dosing pump is an electromagnetic diaphragm metering pump. The frequency of the electromagnetic diaphragm metering pump can be adjusted to add an appropriate amount of disinfectant to the disinfection tank.


H. Self-priming pump


Two self-priming pumps are installed in the equipment room, one for each use. According to the liquid level of the disinfection tank, the self-priming pump automatically sucks the treated fresh water in the disinfection tank and will finish the storage tank after the water is processed.


The above is the technical principle and equipment composition of the school laboratory wastewater integrated equipment summarized by Xiaobian. I hope it will help you.
