◆ Sources and Characteristics of Domestic Sewage
Wastewater from daily life primarily originates from water used and contaminated by domestic waste. It includes water from washing, cooking, and flushing toilets. The quality and volume of the water vary with the seasons, with higher usage and lower concentration in summer, and less volume and higher concentration in winter. The main pollutants are COD, BOD, and SS.
Overview of Wastewater Treatment Equipment for Domestic Use:
The integrated wastewater treatment equipment is made of Q235-A.F steel plates. The equipment is manufactured, tested, and inspected in accordance with relevant standards to ensure the quality of the integrated unit. The inner and outer walls of the equipment are treated for corrosion resistance, and a cover is added to the top with a maintenance access hole for ease of maintenance. The equipment can be buried underground, with grass cover plants planted on the ground surface, which not only maintains the aesthetics of the community but also contributes to land area conservation. The wastewater treatment equipment can also be placed above ground. The outer wall of the equipment is made of steel sandwich panels for insulation and decorative purposes. The sandwich panels use self-extinguishing foam plastic as the core material, with colored steel coated plates as the surface layer, compounded into insulating sandwich panels using a specific process. This material is characterized by its light weight, corrosion resistance, and good thermal insulation properties.
Wastewater treatment levels directly impact the quality of life for residents. The development and application of household wastewater treatment equipment must adhere to relevant principles. Starting from self-construction and wastewater treatment, adopt suitable technical processes, utilize modular design, and thoroughly consider factors such as equipment stability and ease of daily maintenance. This will enhance the treatment efficiency and improve the quality of life in residential areas.
