Integrated urban sewage treatment equipment and wastewater treatment device

Integrated urban sewage treatment equipment and wastewater treatment deviceIt refers to various equipment and processes used to treat urban sewage, whose main function is to remove or reduce harmful substances and pollutants in urban sewage to the national discharge standards, in order to protect the water environment and maintain public health. Next, Zhongke Huarui will provide you with a detailed introduction to the device.

Equipment Classification

Integrated domestic sewage treatment equipment: This equipment integrates multiple sewage treatment processes into a compact device, usually consisting of a box, inlet, outlet, aeration system, packing, filtration system, disinfection device, and other parts. Its advantages are small footprint, easy installation, and suitable for urban communities, tourist attractions, and other places with relatively small and dispersed sewage volume.

Underground domestic sewage treatment equipment: This equipment is installed underground and its structural design fully considers the characteristics of the underground environment, including pre-treatment area, biological treatment area, sedimentation area, and disinfection area. Its advantages lie in not occupying ground space, having minimal impact on the surrounding landscape, being suitable for cold regions, and effectively treating domestic sewage. It is widely used in areas with high requirements for environmental aesthetics.

Combination type domestic sewage treatment equipment: This equipment combines multiple independent treatment units according to different sewage treatment needs. These units can be flexibly combined, such as combining different types of biological treatment units, physicochemical treatment units, etc., to adapt to complex and variable sewage quality and treatment scale, commonly used in large residential areas, industrial parks, etc.

Operating principle

Urban domestic sewage treatment equipment usually adopts a comprehensive process combining physical, chemical, and biological treatment. The main operating principles include the following stages:

Pre treatment stage: Remove large suspended particles, floating debris, and some oils and fats from the wastewater to reduce the burden on subsequent treatment units. Common pre-treatment facilities include grilles and sedimentation tanks.

Biological treatment stage: This is the core process of domestic sewage treatment, which decomposes organic pollutants through microbial metabolism and converts them into stable inorganic substances or low toxicity organisms. Common biological treatment processes include activated sludge process and biofilm process.

Deep treatment stage: aimed at further removing dissolved organic matter, nitrogen, phosphorus and other nutrients, as well as pathogenic microorganisms from wastewater, to improve effluent quality. Common deep processing techniques include coagulation sedimentation, filtration, and disinfection.

Common device types and their functions

Air flotation machine: uses small air bubbles to generate impurities on the surface of the medium, removing impurities with a specific gravity close to water.

Flotation machine: separates small suspended solids, algae, and other small aggregates from surface water.

Aeration machine: Inject microbubbles into wastewater through an aeration impeller to promote physical and chemical flocculation of suspended solids.

Drum filter: solid-liquid separation is achieved through a mesh filter.

Centrifuge: uses centrifugal force to separate solid particles and liquids in suspension.

Sludge dewatering machine: used for dewatering of sludge, suitable for reducing and stabilizing various types of sludge.
