This invention discloses a wastewater treatment system, belonging to the field of wastewater treatment. It includes primary physical filtration, secondary biological treatment, and tertiary advanced treatment. Its key feature is the addition of MBBR suspended media to the anoxic and aerobic tanks of the secondary biological treatment, increasing the amount of microorganisms attached and thus effectively improving biological treatment efficiency. The tertiary advanced treatment employs membrane technology for separation and gradation, with progressively smaller pore sizes at each stage, allowing for the interception of pollutants at each stage, resulting in deep water purification. The effluent can be reused, improving the comprehensive utilization rate of water resources and playing a positive role in water conservation and environmental protection.

The invention relates to a UV / H2O2 and coagulative precipitation synergetic COD / organophosphorus wastewater treatment method which comprises the following steps: pretreating COD / organophosphorus wastewater to remove suspended solids and oil substances in the wastewater; detecting the COD value and the organophosphorus content of the pretreated wastewater, and calculating the dosage of H2O2 according to the detection result; introducing the wastewater added with H2O2 into a photocatalytic oxidation circulation system, starting a UV lamp tube to carry out circulation oxidation treatment, and sampling and detecting according to a preset time interval during the period; introducing the wastewater subjected to UV / H2O2 photocatalytic oxidation treatment into a coagulation reaction tank, adding a coagulant and stirring; and introducing the wastewater subjected to the coagulation reaction into a sedimentation tank for solid-liquid separation. The invention aims to provide the COD / organophosphorus wastewater treatment method with synergism of UV / H2O2 and coagulating sedimentation, which has the advantages of strong suitability, no secondary pollution, simple process and stable treatment effect.

This application relates to the field of wastewater treatment technology and proposes a wastewater treatment system comprising a biological filter, a collection area, and an constructed wetland arranged sequentially from the inside out. The biological filter includes a water distribution device, a filter media layer, and a drainage system. Wastewater is sprayed onto the surface of the filter media layer through the water distribution device, flows through the filter media layer under gravity for biodegradation, and then enters the collection area through the drainage system. The collection area is located around the periphery of the biological filter and is connected to the drainage system. The collection area is used to collect the effluent from the biological filter and distribute it to the constructed wetland. The constructed wetland includes a plant layer and a packing layer arranged from top to bottom. Wastewater enters the constructed wetland from the collection area and flows through the plant layer and packing layer for purification treatment before being discharged after meeting standards. Through the cooperation of the biological filter and the vertical subsurface flow constructed wetland, the clogging problem of the constructed wetland is effectively improved. Through the purification effect of the packing layer and the plant layer, deep treatment of pollutants is achieved, ensuring that the effluent quality meets standards.

This invention relates to the field of wastewater treatment technology, specifically disclosing a photoanode material, a photoanode, its preparation method, and its application in wastewater treatment. The photoanode material comprises an FeSe2 array layer and a Bi2O2WO4 layer supported on the FeSe2 array layer. FeSe2 has a narrow band gap, good light absorption performance, and photogenerated charge separation capability, which can sensitize other semiconductors with wider band gaps to form heterojunctions, promoting the improvement of photocurrent density and electron quantum yield, and enhancing the photoelectric conversion efficiency of the catalytic material. Bi2O2WO4 is composed of [Bi2O2]. 2+ Layers and [WO4] 2‑ The vertically alternating layers facilitate the separation of photogenerated electrons and holes, thereby enhancing the catalytic oxidation activity of the electrode. The combination of Bi₂O₂WO₄ and FeSe₂ improves their respective solar photoresponse capabilities and photoelectrocatalytic performance, offering significant advantages in environmental engineering.
