Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a universal laboratory sewage treatment device. Background Art
[0002] In universities, research institutes, and corporate laboratories, various scientific research experiments are carried out every day, and these experiments produce a wide variety of sewage. These sewages are not only complex in composition, but also contain a large number of harmful substances, such as acids, alkalis, organic pollutants, etc., which pose a serious threat to the environment and human health. At present, although there are a variety of water treatment systems and different water treatment technologies for the treatment of these sewages, the system costs are generally high. However, for some laboratories with limited funds, this is a considerable expense. Secondly, these systems can often only treat a certain type of sewage and cannot meet the needs of multiple types of experiments. This requires laboratories to replace different treatment equipment for different types of experiments when treating sewage, which greatly increases the workload and operating costs of the laboratory.
[0003] The existing sewage treatment system is large, requires large equipment investment, is cumbersome and complex to operate, and has high daily operating costs. It generally cannot meet the requirements of most small laboratories for a simple, integrated and universal sewage treatment device to reduce laboratory operating costs and improve laboratory work efficiency.

The device adopts an integrated universal sewage treatment system consisting of an adjusting tank and a degradation and disinfection tank. The laboratory sewage is collected in a buffer tank. After reaching the set water level, it is pumped into the adjusting tank arranged at a high position by a sewage pump for acid-base neutralization treatment. The sewage after acid-base neutralization flows into the degradation and disinfection tank from the automatic valve at the bottom of the tank for disinfection and degradation treatment, so that the laboratory sewage meets the discharge standards. The device has a simple structure, a small size, high efficiency, environmental protection, easy operation, high practicality, and can adapt to a variety of different types of sewage. It can not only reduce the operating cost of the laboratory, but also improve the work efficiency of the laboratory, better protect the environment and human health, and has broad application prospects and use value.
[0005] The specific technical scheme for achieving the purpose of the utility model is: a universal laboratory sewage treatment device, which is characterized in that the sewage treatment device consists of a buffer tank, a sewage pump, an adjusting tank and a degradation and disinfection tank, the laboratory sewage is collected in the buffer tank, and after reaching the set water level, it is pumped into the adjusting tank arranged at a high position by the sewage pump for acid-base neutralization treatment, and the acid-base neutralized sewage flows into the degradation and disinfection tank from the automatic valve at the bottom of the tank for disinfection and degradation treatment, so that the laboratory sewage meets the discharge standards, the buffer tank is provided with an inlet valve and a liquid level detector; the sewage pump is arranged on the pipeline connecting the buffer tank and the adjusting tank; the adjusting tank is a high-level tank equipped with a stirrer and a pH automatic controller, and an acid-base neutralization system consisting of an acid tank and an alkali tank is arranged on the top, and a pipeline with an automatic valve at the bottom of the tank is connected to the degradation and disinfection tank; the degradation and disinfection tank is provided with a stirrer and a drug dissolving tank; the drug dissolving tank is arranged above the degradation and disinfection tank, and a drug dissolving stirrer is arranged in the drug dissolving tank.
[0006] Compared with the prior art, the utility model has the characteristics of high efficiency, environmental protection, and easy operation. At the same time, it can adapt to a variety of different types of sewage, which can not only reduce the operating costs of the laboratory, but also improve the work efficiency of the laboratory, and at the same time better protect the environment and human health. The device has a simple structure, a small size, simple operation, and can be started and stopped at any time. It can be applied to the neutralization, degradation, and disinfection of various types of laboratory sewage. It has strong versatility and has a wide range of application prospects and use value.
