Garbage sorting Sorting facilitates the disposal of garbage and some of them. It can effectively red

Can be **garbage:

It mainly includes five categories: waste paper, plastic, glass, metal and cloth. Waste paper: mainly including newspapers, periodicals, books, various packaging paper, office paper, advertising paper, cartons, etc., but pay attention to paper towels and toilet paper due to the strong water solubility.

Plastics: mainly include all kinds of plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc. Glass:

It mainly includes all kinds of glass bottles, broken glass pieces, mirrors, light bulbs, thermoses, etc. Metal objects: mainly including cans, cans, etc.

Fabrics: mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc. Through comprehensive treatment, pollution can be reduced and resources can be saved.

For example, 850 kilograms of paper can be made for every 1 ton of waste paper, saving 300 kilograms of wood, reducing pollution by 74% compared with the same amount of production; 0 7 tons of secondary raw materials can be obtained for every 1 ton of plastic beverage bottles; Every 1 ton of scrap steel can be made 0 9 tons of steel, which is 47% cost saving, 75% less air pollution, and 97% less water pollution and solid waste than ore smelting.

Kitchen waste: including leftovers, bones, roots, leaves, peels and other food waste, composted by biotechnology on-site, each ton can produce 0 3 tons of organic fertilizer.

Hazardous waste: including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired medicines, etc., which require special and safe disposal.

Other garbage: including bricks, ceramics, muck, toilet waste paper, paper towels and other difficult wastes in addition to the above types of garbage, sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

Convenient for the disposal of some toxic waste.

Summary. First of all, residents collect and dispose of the garbage generated by their daily lives in the garbage cans nearby.

The municipal garbage collection and transportation vehicle collects the garbage from the garbage bin at the designated garbage collection site every day and transports it uniformly.

Waste collection trucks transfer the collected waste to landfills or waste-to-energy plants.

Waste is landfilled or harmlessly disposed of, incinerated for power generation.

Kitchen waste refers to the garbage generated in residents' daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, peels, eggshells, tea residues, bones, etc., which are mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

Food waste contains extremely high levels of moisture and organic matter, which can easily perish and produce foul odors. After proper treatment and processing, it can be converted into new resources, and the high organic content allows it to be used as fertilizer, feed, biogas for fuel or power generation after strict treatment, and the oil and fat part can be used to prepare biofuels.

Domestic waste composting is a method of treating and utilizing garbage, which is to use microorganisms such as bacteria, yeasts, fungi and actinomycetes in garbage or soil to degrade (digest) the organic matter in garbage through biochemical reactions to form a substance similar to corrosive soil, which is used as fertilizer and used to improve soil.

Waste composting technology has long been applied in Chinese agricultural activities, and it has been studied as a science since 1920. According to the principle of bacterial decomposition, it is divided into high-temperature oxygen (good) oxygen method and low-temperature anaerobic compost. According to the composting method, it is divided into open composting method and mechanical composting.

This includes paper, wood, plants, food, manure, fertilizer, and more.

Also known as composting. It refers to the biochemical process that uses microorganisms widely present in nature to promote the conversion of degradable organic matter into stable humus in solid waste in a controlled manner.

Every time the kitchen garbage is put inside, it can be turned into organic fertilizer in more than a month, which is suitable for indoor composting, no peculiar smell, and is a reliable method for environmental protection and vegetable growers.

Food waste composting is the process of using microorganisms and small insects in nature to break down organic matter (food waste) in the presence of air and water. The final product is called food waste fertilizer, which is rich in easy-to-use phytonutrients that form part of a healthy soil. It is recommended to buy a bucket and wooden box for composting food waste.

It is best made on the balcony or outdoors. When the food waste compost is fermented, it will have a taste (mainly ammonia and hydrogen sulfide).

Carbon-containing organic matter such as dried leaves, wood chips, paper, peanut shells, melon seed shells, etc.

Nitrogenous organic compounds such as fruit and vegetable waste, coffee grounds, malt powder, etc.

1. Air 2. Appropriate amount of water 3. Treat kitchen waste and turn waste into treasure.

Easy 6 Steps:

1. Separate edible kitchen waste (vegetable peels, fruit peels, a small amount of wasted cooked food) into containers.

2. Collect the dried organic matter (dried leaves, sawdust) in a small container.

3. Take a box or a bucket and drill 4 5 different holes around the container to let air in.

4. Spread a layer of soil on the bottom.

5. Now start adding food waste alternately wet waste (vegetable and fruit skins) and dry waste (straw, sawdust, dry leaves).

6. Cover this container with plastic sheeting or wooden planks to help retain moisture and heat. Some advice Every few days, use a rake to turn the pile quickly to provide inflation. If you feel that the pile is too dry, sprinkle it with some water and make it moist.

Within 2-3 months, your food waste should start to form compost on dry, dark brown soil. There are also ready-made, kitted tools for food waste composting. With time and a little patience, you might enjoy composting food waste.

It is not recommended to use leftover meat, bones, leftovers, leftovers, etc. from food waste.

By sorting, ** and composting, a family of four can reduce waste by 1,000 kg to less than 100 kg per year. Imagine that 90% of all the garbage in Chennai disappeared overnight, a clean green city – and it will help you start your composting journey.

5 10 The purpose of garbage classification is to improve the resource value and economic value of garbage, and reduce the amount of garbage disposal and treatment facilities.

Hello dear<>

The answer you are looking for: 5 10 The purpose of garbage classification is to improve the resource value and economic value of garbage, reduce the amount of garbage disposal and treatment as follows: the construction cost of preparation, and reduce the pollution and waste of resources to the environment.

Through garbage classification, different types of garbage such as garbage, hazardous garbage, wet garbage and dry garbage can be collected separately and treated slowly, so as to maximize the utilization of garbage resources. Among them, the best garbage can be reused to turn waste into treasure and reduce the mining and consumption of natural resources; Hazardous waste can be safely disposed of to reduce the harm to the environment and human body; Wet garbage can be turned into fertilizer through composting and other methods for agricultural production; Dry waste can be disposed of by incineration, reducing the occupation and pollution of landfills. In this way, garbage sorting can maximize the resource value and economic value of garbage, and at the same time reduce the amount of garbage treatment and the construction cost of treatment equipment, so as to achieve the goal of sustainable development.

Which of the following garbage can be taken and composted to make fertilizer () aFood waste.

b.The others rushed to the garbage and sang to the min.

c.Hazardous waste.

d.Can be ** things.

Correct Answer: a

Answer]: False.

Analysis: For the treatment of municipal garbage, if the content of inorganic matter in the garbage is high, it is advisable to use the landfill method; If the content of biodegradable organic matter in the garbage is high, it is advisable to use the method of dismantling and composting dust; If the content of refractory biodegradable organic matter in the garbage is high, incineration should be used.
