Description

Technical Field

[0001] The utility model relates to the technical field of garbage processing equipment, in particular to a wastewater collection and processing device for environmental protection. Background Art

[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as primary rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution.

[0003] Laboratory wastewater is a common type of wastewater. During the laboratory wastewater treatment process, wastewater collection and treatment equipment is used to precipitate harmful substances in the wastewater and neutralize the pH value of the wastewater. Common wastewater collection and treatment equipment only stores wastewater in storage barrels and is unable to stir the wastewater with alkali solution, resulting in the alkali solution being unable to fully mix with the wastewater.

[0004] The Chinese utility model patent currently announced as: CN212476234U discloses a laboratory wastewater collection and treatment device, including a bottom plate, a storage barrel is provided on the bottom plate, a connecting pipe is fixedly connected to one side of the storage barrel, the connecting pipe is connected to the inner cavity of the storage barrel, the pipe mouth of the connecting pipe faces upward and the pipe mouth is connected to an end cap by a thread, and a connecting hole is opened on the end cap; a bracket is fixedly connected to the bottom plate, a water receiving tray is arranged on the upper end of the bracket, a downpipe is connected to the bottom of the water receiving tray, and the lower end of the downpipe is inserted in the connecting hole; a feeding barrel is fixedly connected to the bottom plate, a peristaltic pump is fixedly installed on the top cover of the feeding barrel, a water pumping hose is installed on the peristaltic pump, and the peristaltic pump is used to pump the alkali solution in the feeding barrel into the storage barrel. The utility model is convenient to use and easy to disassemble and install.

[0005] In view of the above problems, existing patents have provided solutions, but the existing wastewater collection and treatment devices use a feeding bucket and a peristaltic pump to add alkali solution to the storage bucket, which is convenient for adding, but cannot effectively mix the wastewater and the alkali solution. Therefore, it is necessary to fully stir the wastewater and the alkali solution through a stirring structure to improve the neutralization efficiency of the pH value of the wastewater. However, whether it is the wastewater collection and treatment device in the prior art or the wastewater collection and treatment device in the provided improved technology, it is impossible to achieve the problem of fully stirring the wastewater and the alkali solution, and at the same time, it is impossible to automatically detect the pH value of the wastewater.

[0006] Therefore, a wastewater collection and treatment device for environmental protection is proposed. Utility Model Content
