Abstract

The invention discloses a photovoltaic wastewater advanced treatment system and an application method. The photovoltaic wastewater advanced treatment system comprises a wastewater treatment unit and awastewater recycling unit, the wastewater treatment unit consists of a homogenizing regulation tank, a coagulation air floatation tank, a sedimentation silicon removal tank, a composite two-section AO biological tank, a secondary sedimentation tank, a sludge pump room, a powdered carbon adsorption coagulation sedimentation tank and a V-shaped filter tank which are connected in sequence; the wastewater recycling unit is composed of an ultrafiltration module and a reverse osmosis module; the wastewater treatment unit is connected with the wastewater recycling unit through a horizontal centrifugal pump, and the system further removes pollutants in sewage, provides a process water source for enterprises, and mainly solves the problem that the development of the photovoltaic industry is limited in water resource shortage regions.

Description

technical field [0001] The invention relates to the field of advanced treatment and reuse of special industrial wastewater, in particular to a photovoltaic wastewater advanced treatment system and an application method. Background technique [0002] Under the severe situation of the depletion of global fossil energy, photovoltaic power generation technology continues to improve, and industrialization technology is basically mature. Countries around the world have successively issued a series of regulations and policies to promote the development of the photovoltaic industry. For a long period of time in the future, the photovoltaic industry will Enter a period of rapid development. [0003] The photovoltaic industry is also a high water consumption and high pollution industry. It is a restrictive development industry in most areas of my country where water resources are scarce and the water environment is deteriorating. The advanced treatment and reuse technology of photovol...
