Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a flocculent separation device for photovoltaic wastewater treatment. Background Art

[0002] Photovoltaic wastewater treatment is the process of treating wastewater generated during solar photovoltaic power generation. Common wastewater in photovoltaic power generation includes cleaning water, cooling water, and wastewater from photovoltaic module production. This wastewater typically contains various organic and inorganic substances, as well as suspended solids (floc), requiring treatment before it meets discharge or reuse standards.

[0003] PV wastewater treatment floc separation devices effectively separate and remove flocs from wastewater to meet environmental protection requirements, protect the environment, and ensure the sustainable development of the photovoltaic power generation industry. When separating flocs from PV wastewater, most agitation mechanisms may not adequately mix the flocs and reagents, potentially trapping sediment and flocs in dead corners and preventing effective mixing. This results in insufficient contact between the flocs and the flocculant, hindering floc coagulation and preventing them from being effectively dispersed and stirred, making it difficult to form large agglomerates and quickly settle. After the wastewater and reagents are mixed, the flocs and wastewater enter the sedimentation tank for sedimentation. Without a quick-release mechanism, cleaning and maintaining the inclined tube during wastewater treatment can require increased manpower and time, increasing maintenance costs and potentially leading to increased production downtime. Flocs in the wastewater can also accumulate on the inner wall of the inclined tube, leading to blockage and scaling. Cleaning and maintaining the inclined tube becomes difficult, requiring longer downtime and more complex operations. Utility Model Content
