With the continuous development of production and technology, the application of chemical laboratories is becoming more and more extensive, and the treatment of laboratory wastewater has increasingly become the focus of attention. Laboratory wastewater often contains various organic matter, inorganic salts, heavy metals and other substances that have a serious impact on the environment, so effective measures must be taken to treat and meet the discharge standards to reduce the impact on the surrounding environment. This article focuses on the relevant content of sewage treatment equipment in chemical laboratories.
1. Types of sewage treatment equipment in chemical laboratories.
1.Biological sludge treatment equipment: The main principle of this equipment is to use biological flora to decompose and remove organic matter in sewage, and at the same time, the oxygen released plays a role in increasing oxygen. The equipment enters the wastewater into the equipment through the inlet pipe of the equipment, and passes through the sludge tank, aeration tank, sedimentation tank and other parts, and the treated wastewater water quality meets the discharge standard.
2.Coagulation and sedimentation treatment equipment: This equipment mainly uses some chemicals as coagulants to gradually precipitate the suspended particles in the wastewater. Its working principle is to add chemicals to wastewater to achieve the effect of removing suspended particles and suspended solids, which can effectively remove the color, suspended solids, grease and other substances in the sewage.
3.Membrane Separation Treatment Equipment: This equipment uses a set of membrane filters to effectively screen impurities and organics in the wastewater, where the wastewater is retained on one side and the clean water is out.
Second, the operation process of sewage treatment equipment in chemical laboratory.
The operation process of the sewage treatment equipment in the chemical laboratory includes the following links:
1.Preliminary treatment: Sewage screening, also known as routine treatment, is carried out to remove solid particles from wastewater to reduce the burden of subsequent treatment.
2.Biochemical treatment: The treated sewage is introduced into the biological treatment tank, the microbial community in the microbial metabolic unit is used to degrade the organic matter, and the sewage is stirred by the released oxygen to achieve the effect of oxygenation.
3.Coagulation and sedimentation: After the preliminary treatment and biochemical treatment, the wastewater is introduced into the coagulation tank, and an appropriate amount of coagulant is added, and the predetermined effluent effect is gradually achieved through rapid precipitation and filtration.
4.Disinfection treatment: Finally, it is disinfected to ensure that the treated water quality meets the requirements.
3. Advantages of sewage treatment equipment in chemical laboratories.
1.Through the operation of wastewater treatment equipment, the wastewater is continuously circulated, and the chemical substances contained in the wastewater are effectively separated, which achieves the effect of saving resources and meeting the water quality discharge standards.
2.The pollution control effect is obvious, and the equipment itself has strong stability and treatment capacity, even if it occurs when the raw materials, production process or other factors cause fluctuations, it can better ensure the stability of the treated water quality.
3.The equipment has low operating costs and simple maintenance. Because the equipment uses some important basic principles, and the equipment itself has high reliability, the cost is relatively low in the operation and maintenance process, and it has good economy and practical benefits.
Fourth, the use of sewage treatment equipment in chemical laboratories.
The sewage treatment equipment of the chemical laboratory can not only be used for the sewage treatment of the laboratory itself, but also widely used in the sewage treatment of factories, chemical plants, pharmaceutical factories and other industries. In the daily production process, a large amount of wastewater may be generated in the manufacturing process of these industries, and if it is not treated in time, it will have an unbearable impact on the environment, so the use scenarios of sewage treatment equipment in chemical laboratories will become more and more extensive.
Conclusion: Chemical laboratory sewage treatment equipment can make sewage be effectively treated, not only to ensure environmental protection standards, but also to save water resources, is an environmentally friendly and economical treatment method, and its application scenarios are becoming more and more extensive. However, in the process of use and operation, it is necessary to pay attention to the normal maintenance and operation of the equipment to ensure the smooth operation of the equipment and maintain the stability of the treated water quality.
