Industrial wastewater treatment equipment can realize simultaneous nitrification and denitrification, remove total nitrogen in sewage, can achieve biological phosphorus removal, high treatment efficiency, and good effluent water quality; adsorption selection area in the pond, no sludge expansion, small sludge production; industrial wastewater The processing equipment performs biological treatment and mud-water separation treatment in the same pool, and there is no need to set up a sedimentation tank and a second sedimentation tank. The operation cost is low, the project investment is for preservation, and the land occupation is occupied; the operation cycle is flexible, the impact resistance is strong, and the load Good performance.
Before the construction of industrial wastewater treatment equipment, the corresponding civil works should be basically completed. When the installation project must be coordinated with the civil engineering, the relevant equipment foundation, floor and pipeline trench should be completed, and the strength of the concrete should not be low. At 75% of design strength, building materials and debris near the construction site should be removed.
When the industrial wastewater treatment equipment uses the building structure as a temporary lifting fulcrum, the necessary calculation of the structural bearing capacity shall be performed and the consent of the design department shall be obtained; the industrial wastewater treatment equipment installation project shall have design and construction drawings or equipment technical documents before construction. And reasonably arrange temporary transportation roads, water sources, power sources, lighting and other facilities, main materials and machinery, and labor services.
Industrial wastewater treatment equipment technology can be divided into biological contact oxidation methods, SBR, A / O and A2 / O according to the process. The principle of commonly used A / O treatment technology is that the microorganisms in the anoxic pool will remove nitrate nitrogen and nitrous acid in sewage Salt nitrogen is reduced to gaseous nitrogen, and at the same time, macromolecular organic substances that are difficult to degrade are decomposed into small molecule easily degradable substances. It has the functions of denitrification, hydrolysis and degradation of certain organic substances; in the aerobic tank, most of the organic matter is treated by microorganisms, enters the secondary sedimentation tank to separate muddy water, and is discharged after disinfection.
