This paper mainly introduces the thermal desorption repair technology of soil remediation technology in contaminated sites. In-situ biodegradation is the process of degrading (metabolizing) organic contaminants in the soil with indigenous or inoculated microorganisms (ie, fungi, other microbial organisms) and converting the contaminating material into harmless end products. Nutrients, oxygen and other additives can be used to enhance biodegradation. The technology is characterized by: (1) In the implementation of bioremediation, the efficiency of remediation is affected by many factors such as the nature of pollutants, the ecological structure of soil microorganisms and the nature of soil. If soil media inhibits contaminant microorganisms, the goal of removal may not be achieved. (2) High concentration of heavy metals, high chlorinated organic compounds, long-chain hydrocarbons, may be toxic to microorganisms. Biodegradation slows at low temperatures. (3) repair cycle is longer, usually takes a few years. (4) It is necessary to control the temperature of the site, the pH value, the amount of nutrients and other elements to make it comply with the living conditions of microorganisms. (5) lower energy consumption, you can repair a larger area of ​​contaminated sites. (6) Suitable for the application of pollutants to saturated soil or groundwater. The repair cost of this technology is 55-360 $ / m3, the repair cycle is 6-24 months, the pollutants that can be removed are non-halogenated volatile organic compounds, halogenated volatile organic compounds, non-halogenated Of semi-volatile organic compounds, fuels, explosives and persistent organic pollutants. Pollutant removal rate of 70 to 90%.
Fireplace passes convection and heat radiate, heat even, the fresh air of convection adjusts automatically and improve bedroom air quality, warm means natural and comfortable.
Fireplace besides having comfortable heating effect, still have good humification function, it will be helpful for health.

Real fire fireplaces are heated primarily by wood or compressed wood combustion. Heating power is far greater than all kinds of air conditioning, heating devices. At a temperature of -10℃, the temperature of a 40-100 square meter house can rise to about 20℃ by lighting the fireplace for about 10 minutes.
