The Harm and Challenge of Domestic Waste to Human Beings and the Environmental Protection Application of Waste Compression Stations
With the rapid growth of the world economy, the rapid expansion of urban population, the continuous improvement of living and consumption levels, and the transformation of people's living habits from "conservation" to "abandonment", the production of urban solid waste continues to increase. Moreover, due to the extensive application of polymer synthetic materials, plastics, and toxic industrial substances, the composition of solid waste is becoming increasingly complex, all of which cause significant damage to the environment, And directly threaten human health and survival.
According to expert statistics, there are currently 668 cities in China, more than two-thirds of which are surrounded by garbage belts. According to aerial remote sensing measurements, there are 7000 garbage dumps over 50 square meters in the suburbs of Beijing. This year, Beijing generated 2.85 million tons of garbage, equivalent to two and a half Jingshan. From the 1990s to the present, it can be inferred that Beijing has been surrounded by more than 20 huge garbage mountains like Jingshan. The daily output of urban household waste in China is 1.0-1.2Kg per capita, with an average annual growth rate of 10%. The production of household waste in large, small, and medium-sized cities (towns) in China is close to 200 million tons, affecting the city's appearance and appearance. Some light objects float in the air by the wind, hang on the branches and wires, float on the water, and emit a variety of disgusting odors such as hydrogen sulfide, ammonia, benzene, acetone, etc., providing a hotbed for mosquitoes, flies, mice and pathogenic bacteria. Garbage contains sufficient food and an appropriate amount of water and air, making it a good place for mosquitoes, flies, mice, cockroaches, and various pathogenic bacteria to live, breed, and reproduce. Therefore, improper disposal of garbage will inevitably become a breeding ground for cultivating and spreading pests and diseases.
At present, the relatively developed cities in China have not solved the problem of various garbage blocks and temporary storage areas. All kinds of garbage are constantly emitting various bacteria and odors, as well as the spread of various pathogens such as mosquitoes, flies, mice, cockroaches, etc.
The scientific and effective method of temporarily storing various types of garbage in urban areas across the country, compressing the volume of garbage, and isolating garbage from the outside world is currently an urgent problem to be solved nationwide. Compression transfer equipment, specifically designed for the collection and treatment of household waste, is a type of submersible equipment that is hidden below the ground and does not occupy space above the ground. It is easy to operate and has good sealing performance. During the operation, no garbage is visible and has a function to eliminate garbage odor. The entire compression process is completed below the ground, which is simple and safe.
The environmental protection of garbage compression stations is now widely used in urban sanitation construction, which has the following obvious technical characteristics
1. The garbage compression station is located underground and is a fully sealed structure, which avoids exposure to the sun and rainwater, thereby protecting the living environment around residents.
2. Due to its fully enclosed nature, the garbage compression station avoids the breeding of mice, mosquitoes, and flies, as well as the transmission of diseases, preventing the flipping and picking up of garbage.
3. Due to its compression function, the garbage compression station can compress sewage and directly discharge it into the sewer, greatly alleviating the pollution of sewage to the atmosphere.
4. Garbage transportation is promoted through compression in fully sealed dump trucks, avoiding secondary pollution during transportation. Due to the compression, transportation efficiency is greatly improved and transportation costs are reduced.
(Note: The compression ratio of household waste is 1:0.5, and the compression ratio of household waste is 1:0.8. The LYJ • D • S-08 type box has a volume of 8 m3, which can simultaneously meet the storage and transportation of household waste for 800-1000 households of 3 * *.)
