The inorganic wastewater treatment equipment in Letep Laboratory comprehensively treats the organic, inorganic, and biological wastewater generated in the laboratory through unique treatment processes such as wastewater collection unit, automatic adjustment unit, coagulation air flotation automatic stirring unit, coagulation assisted sedimentation reaction unit, sedimentation separation unit, multi-stage advanced oxidation treatment unit, multi-stage decomposition degradation treatment unit, high and low potential difference microelectrolysis technology, electrochemical oxidation-reduction, two-stage organic biological activity treatment technology, new biochemical reaction treatment technology, new packed bed optical wave catalytic reaction for organic wastewater, and microbial reaction tank. It can effectively remove the pollutants in the wastewaterCOD、BOD、SSDifferent treatment technologies and control systems are used for wastewater treatment based on the composition of different experimental wastewater, such as chromaticity and heavy metal ions. The device is operated through the human-machine interface operating system, and the device runs according to thePLCThe program set by the controller andPH/ORPThe parameters set by the instrument are operated fully automatically, with multi-level online monitoring. The control system automatically calculates the composition and concentration of different wastewater and then automatically dispenses drugs in proportion, which is more scientific and rational, ensuring the treatment effect of wastewater while saving drug consumption and achieving fully automatic unmanned operation.

Letep Laboratory's inorganic wastewater treatment equipment has a high degree of automation, good treatment effect, small footprint, easy operation and management, and does not require dedicated personnel. It is a set of laboratory comprehensive wastewater treatment equipment specially designed for various industries at home and abroad. It is highly praised by users and widely used in secondary and higher education institutions, research institutes, food and drug inspection, product quality inspection institutes, disease control centers, environmental monitoring, agricultural product quality inspection, inspection and quarantine, grain and oil testing, animal disease control, blood stations, animal husbandry, medical institutions, hospitals, biopharmaceuticals, petrochemicals, enterprises and other laboratories and laboratories. After treatment, the wastewater meets the comprehensive discharge standards for wastewater【GB8978-1996】According to the first, second, and third level standards in China, the treated wastewater can be discharged into the municipal sewage network, surface water, or river water, and can also be reused through reprocessing processes.

3、 Model selection of laboratory inorganic wastewater treatment equipment

Note: The processing capacity of laboratory comprehensive waste liquid treatment equipment can be customized according to the actual needs of users.
