Comprehensive wastewater treatment device for physical and chemical laboratory

Abstract

The invention discloses a comprehensive wastewater treatment device for a physical and chemical laboratory. The comprehensive wastewater treatment device comprises a wastewater collecting device, a microelectrolysis detoxification module, a solid microorganism degrading and purifying module, an automatic pH regulating module, an automatic dissolved oxygen adjusting module, a terminal particle separation module, a solid-liquid separation device and a control module, wherein the microelectrolysis detoxification module is connected with the wastewater collecting device to perform electrolytic treatment on wastewater; the solid microorganism degrading and purifying module is connected with the microelectrolysis detoxification module to perform biological degradation on the wastewater after electrolytic treatment; the automatic pH regulating module is connected with the microelectrolysis detoxification module and the solid microorganism degrading and purifying module to perform pH regulation on the wastewater entering the microelectrolysis detoxification module and the solid microorganism degrading and purifying module; the solid-liquid separation device is connected with the microelectrolysis detoxification module and the solid microorganism degrading and purifying module. According to the wastewater treatment device of the embodiment of the invention, the technology is advanced, the process is short, and the secondary pollution is small.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically, to a comprehensive wastewater treatment device for physical and chemical laboratories. Background technique [0002] With the rapid development of various new drug development and the expansion of college enrollment in recent years, the number of students has increased sharply, the number of chemical laboratories has doubled, and the amount of laboratory wastewater is increasing. Many laboratories discharge wastewater into the sewer without any treatment. Because the composition of the experimental wastewater is quite complex, containing more acid, alkali, cyanide, hexavalent chromium, arsenic, phenol, benzene and other toxic and harmful substances, direct discharge will inevitably cause pollution to people's domestic water and living environment. An economical, efficient, energy-saving, environmentally friendly, and applicable chemical laboratory wastewater tr...

Problems solved by technology

[0002] With the rapid development of various new drug development and the expansion of college enrollment in recent years, the number of students has increased sharply, the number of chemical laboratories has doubled, and the amount of laboratory wastewater is increasing. Many laboratories discharge wastewater into the sewer without any treatment. Because the composition of the experimental wastewater is quite complex, containing more acid, alkali, cyanide, hexavalent chromium, arsenic, phenol, benzene and other toxic and harmful substances, direct discharge will inevitably cause pollution to people's domestic water and living environment. An economical, efficient, energy-saving, environmentally friendly, and applicable chemical laboratory wastewater treatment process is urgent

[0003] However, due to the characteristics of laboratory wastewater such as small total discharge, complex pollutant components, intermittent discharge, and large concentration gradient, and most of these institutions are located in university teaching buildings or commercial buildings, they have high requirements for site and environment, so the experiment Indoor wastewater devices must have flexible and diverse treatment processes, and have extremely strict requirements on equipment treatment efficiency and secondary pollution. At present, the methods used for this type of water treatment in the industry are relatively primitive, with single technical means, many secondary pollution, and structural Complex and occupy a large area, poor environmental friendliness, there is no effective solution specifically to deal with this type of wastewater treatment needs
