Description

A kind of purification air coal gangue building blocks and processing method thereof

Technical field

The invention belongs to building block technical field, particularly relate to a kind of purification air coal gangue building blocks and processing method thereof.

Background technology

China's atmospheric pollution is serious all the more, and owing to, in China's environmental improvement, the Market Orientation that only water pollutes with solid waste is administered is higher, and all the other are such as air contaminant treatment, owing to it is subject to weather impact and can shift between different geographical. Therefore, government is relatively low to the enthusiasm of air contaminant treatment all the time, and this market segment is also comparatively weak.

The loss that Chinese city air pollution causes specifically includes that crop that the outdoor health impact (especially chronic bronchitis) that causes with room air pollution, acid deposition the cause lead content high with the loss of forest, material corrosion, particulate matter causes that the nervous system injury of child declines with intelligence. Ministry of Health of China has assert that the respiratory tract disease of chronic obstructive is one of Chinese leading cause of the death, accounts for more than the 1/4 of death according to statistics.

The source of atmospheric pollution can be divided into the big class of natural and artificial two. Natural pollution source is to be formed due to natural cause (such as volcano eruption, forest fire etc.), and man-made pollution source is to be formed owing to people are engaged in production and life activity. In man-made pollution source, (such as automobile, train, aircraft, the steamer) two kinds of fixing (such as chimney, industrial exhaust gas cylinder) and movement can be divided into again. Due to man-made pollution source ubiquity, paid close attention to so carrying out more people compared with natural pollution source. Air primary pollution source has:

(1) industrial undertaking of industrial undertaking is the main source of atmospheric pollution, is also one of the emphasis of atmospheric hygiene protected working. Along with developing rapidly of industry, kind and the quantity of atmosphere pollution are increasing. Due to differences such as the character of industrial undertaking, scale, technical process, raw material and product categories, they are also different to the degree of atmospheric pollution.

(2) life cooking stove and heating boiler are in residential area, along with the concentration of population, substantial amounts of domestic life cooking stove and heating boiler are also required to consume substantial amounts of coal, especially in the winter time the heating time, often making contaminated area full of smoke, this is also a kind of source of atmospheric pollution that can not be ignored.

(3) transportation is in recent decades, and due to the development of transportation cause, the automobile that city travels is increasing, and the passenger and freight transportation such as train, steamer, aircraft is frequent, and these add the new source of atmospheric pollution to city again. Wherein have have a strong impact on be automobile discharge waste gas. The feature of auto-pollution air is that the pollutant the discharged breathing zone from people is close, can directly be sucked by people. The waste gas that car combustion engine is discharged mainly contains carbon monoxide, nitrogen oxides, hydro carbons (Hydrocarbon), lead compound etc.

According to the regulation of China's " ambient air quality ", that monitors every day and issue mainly has three air pollutants indexs: pellet, nitrogen dioxide and sulfur dioxide. The index of these indexs is excellent when 0��50, is good when 51��100, and more than 100 for polluting. " pellet " of standard regulation monitoring refers to the diameter particulate matter less than 10 microns, but does not include " head is less ", particulate matter (being called for short " fine particle ", also known as PM2.5) less than 2.5 microns. In above-mentioned three contamination indexs, pellet ratio in air pollution is maximum, and fine particle accounts for 70%��80% in pellet. When a large amount of fine particles swim aloft, atmospheric visibility will diminish, and sky seems dusky, and meteorology is called " gray haze sky " this phenomenon. And causing the arch-criminal in this gray haze sky is exactly fine particle. According to world's air quality map denotation that US Adm Nati announces, it is that north African and the North China of China, east and central China are whole that whole world fine particle pollutes the highest area, most of China area fine particle mean concentration is close to 80 micrograms/cubic meter, beyond 8 times of the relevant contamination index of World Health Organization's regulation.

Harm that the mankind and living environment thereof are caused by atmospheric pollution and impact, recognized by people gradually, sums up to get up to have following several aspect:

1. the harm to health. Human body has been injured three approach, namely suck contaminated air, surface skin contact stain air and eat the food containing atmosphere pollution, except can causing respiratory tract and pulmonary disease, also cardiovascular system, liver etc. can be produced harm, the life of serious seized people.

2. to biological harm. Animal falls ill containing pollutant food or dead because sucking contaminated air or eat, and atmosphere pollution can make plant disease-resistant power decline, affect growth promoter, blade face generation blemish or withered death.

3. the harm to article. As to textile clothes, leather, metallic article, construction material, cultural and artistic products etc., caused chemical lesion and stain infringement.

4. cause acid precipitation, agricultural, forestry, freshwater aquaculture industry etc. are had a negative impact.

5. destroy high-altitude ozone layer, form Ozone hole, the mankind and biological living environment are produced harm.

6. global climate is produced impact, as increasing of carbon dioxide isothermal chamber gas can cause that earth atmosphere increasing is dim, cause that global weather disaster increases, and for example the particulate such as flue dust increases, and makes atmospheric turbidity increase, weakens solar radiation, affect earth long-wave radiation, cause that synoptic climate is abnormal.

China's atmospheric pollution in recent years is day by day serious, and China's most area fine particle mean concentration is close to 80 micrograms/cubic meter, beyond 8 times of the relevant contamination index of World Health Organization's regulation.Although some Conventional pollution obtain certain control, but new pollution is comed one after another, and brings serious pollution to our environment, and for this, we should use up oneself maximum effort and go to stop the development of atmospheric pollution situation, return our green home. How Air Pollution prevention and control, alleviates harm and the impact of atmospheric pollution, constitutes research topic great and urgent now. And adopt building to absorb degraded harmful substance, it is highly effective means.

Summary of the invention
