Anhui degreasing wastewater treatment equipment

Anhui degreasing wastewater treatment equipmentThe treatment of degreasing wastewater is a common source of pollution in industrial production, and its treatment effect is directly related to ecological environment safety and sustainable development of enterprises. In Anhui region, with the upgrading of manufacturing industry and the improvement of environmental protection requirements, degreasing wastewater treatment technology is gradually developing towards high efficiency and intelligence, forming a governance system centered on source control, process optimization, and resource recycling.

Anhui degreasing wastewater treatment equipmentFrom a technical application perspective, a combination process of 'pretreatment+biochemical treatment' is adopted. Taking industries such as automobile manufacturing and mechanical processing as examples, degreasing wastewater contains a large amount of oil, surfactants, and alkaline substances. During treatment, floating oil and emulsified oil are first removed through oil separation tanks and air flotation equipment. Then, the water quality and quantity are balanced using regulating tanks, and finally enter the anoxic aerobic (A/O) biological reaction system to degrade organic pollutants. The enterprise has also developed high-temperature heat pump coupling treatment technology, which improves treatment efficiency and reduces operating costs through heat recovery. Such equipment has been widely applied in many industrial concentration areas such as degreasing, silane, phosphating, and surface tuning.

Require enterprises to synchronously plan wastewater treatment facilities during the project design phase. As stipulated in the environmental impact assessment of industrial projects in Guangde City, degreasing wastewater must be pre treated in the factory area to meet the third level standard of the Comprehensive Wastewater Discharge Standard (GB8978-1996) before it can be connected to the municipal sewage treatment plant. Defatting wastewater has strong corrosiveness, and special emphasis is placed on the anti-corrosion and anti-seepage design of wastewater treatment stations. It is required that hazardous waste storage sites comply with the "Pollution Control Standards for Hazardous Waste Storage" (GB18597-2023), reflecting the importance of controlling pollution sources.

The dissolved air flotation machines and A2/O integrated equipment from companies such as Shanghai Yishuang are widely used in the province. These devices integrate units such as dosing, reaction, and precipitation, and have the characteristics of small footprint and high degree of automation. The daily processing capacity of a single set of equipment can reach 5-500 cubic meters, which is suitable for enterprises of different scales. At the same time, the introduction of advanced treatment technologies such as membrane bioreactor (MBR) and advanced oxidation enables the treated effluent to meet the requirements for reuse, achieving the recycling of water resources.
