Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a device and a method for simultaneously removing hydrogen peroxide and silicate from wastewater using an integrated photovoltaic cell. Background Art

[0002] Industrial wastewater is an important source of sewage discharge. In recent years, the technology industry represented by photovoltaic new energy and semiconductors has shown a blowout development. However, photovoltaic, chip and other high-tech manufacturing industries consume a huge amount of water. The composition of industrial wastewater is complex, with many toxic components, high concentration of pollutants, poor biodegradability, high difficulty and cost in treatment, and it is easy to cause the drainage water quality to exceed the standard. While restricting the green and sustainable development of these industries, it also causes serious harm to the ecological environment and human health. Therefore, it is urgent to develop wastewater resource utilization technology to realize the rational use of wastewater resources. The use of reclaimed water reuse technology can solve these problems. The treated wastewater can be reused in the workshop as recycled water, reducing the amount of wastewater discharge while also reducing the amount of water used at the source.

[0003] The wastewater discharged from photovoltaic cells is large in volume and has complex components. The hydrogen peroxide and silicates contained in it can easily cause corrosion or blockage of the pipes and equipment of the reclaimed water reuse membrane system, reducing the equipment operating efficiency and increasing the operating and maintenance costs. Therefore, it is necessary to take treatment measures for hydrogen peroxide and silicates in the raw water to improve the water production rate of the subsequent membrane system and extend the service life of the membrane. For pollutants such as hydrogen peroxide and silicates, conventional treatment methods mainly include chemical dosing and chemical precipitation. However, the chemical dosing method has the disadvantages of large dosage and low dosing efficiency. In addition, the chemical precipitation method cannot effectively remove difficult-to-precipitate substances such as high hardness and fine particles. At the same time, a filter press device is required for filtration, which has a high investment cost.

[0004] In summary, the development of an efficient and low-consumption integrated device and method for the simultaneous removal of hydrogen peroxide and silicate from photovoltaic cell wastewater is of great significance and practical value for the resource treatment of silicon solar cell wastewater.
