Domestic wastewater is one of the main causes of water pollution in residential areas, urban areas, commercial - service centers, restaurants - hotels. Daily human activities discharge a large amount of wastewater into the environment. If not treated and discharged directly into the environment, it will cause serious pollution and affect the lives of nearby residents.
Domestic wastewater originates from daily activities such as:
-
Human waste is commonly known as black wastewater (wastewater from toilets from human feces and urine)
-
Waste from cooking, bathing, laundry, and overflowing drainage activities is commonly referred to as gray water.
-
In addition, there are other wastes such as: grease, detergents, chemicals, foaming agents...
Domestic wastewater contains many pollutants such as suspended solids, dissolved organic matter, inorganic salts, nutrients, pathogenic bacteria, and also contains some metals. The concentration of these substances varies according to the amount of water used by households, the amount of water used depends on the water supply capacity, income, usage habits and weather. The harmful effects of these components include reducing oxygen in water sources due to the decomposition of organic matter, eutrophication of water sources due to nitrogen and phosphorus, foaming due to detergents, detergents, odor due to indole;
Households discharging waste directly into the environment has a great impact on the ecosystem in the area, especially the water environment such as rivers, lakes, canals, ditches, etc. This leads to the surrounding environment being polluted by unpleasant odors.
Domestic wastewater is the cause of soil and water pollution if not treated properly. Dirty water flowing into agricultural and livestock areas will have a negative impact on crops and livestock. In the worst case, domestic wastewater after being discharged by families will flow into ponds, streams, and rivers, killing organisms such as shrimp, fish, etc., then the water seeps into the ground and we use it again. Some manifestations of health being affected by water pollution include jaundice, digestive diseases, etc.
Therefore, each household needs to be aware of protecting the environment as well as protecting their own health by the following methods:
-
Minimize the indiscriminate discharge of waste into the environment, instead, use the local sewer collection system.
-
Simple methods can be applied to neutralize wastewater such as using activated carbon filters to reduce odors, colors, etc.
-
Build wastewater tanks and compost pits for households raising livestock.
Today, environmental protection is the responsibility of each citizen, not just an organization or the state. Each individual contributes a small part to environmental protection, contributing to improving the quality of life for the present and future generations.
Protecting the living environment is protecting human health and developing the country's economy.
