Abstract

A treatment method for harmless solid waste comprises the steps that firstly, inorganic oxide particles or hydroxide and a slow release agent are mixed to form a mixture; secondly, the prepared mixture and phosphoric acid are mixed to form an acid solution; thirdly, the acid solution and waste particles are mixed to generate a sizing agent; and fourthly, the sizing agent is solidified. The treatment method for the harmless solid waste is characterized in that oxide grains are fed into a plasma furnace through inorganic oxide to be roasted and then are cooled and pulverized, the temperature applied to the plasma furnace is raised every 10 minutes from the first temperature, in this way, roasting is carried out for 20 minutes, 40 minutes later, the second temperature is reached, and then constant roasting is carried out for 40 minutes at the second temperature to 120 minutes. The method is used for producing building materials, no secondary waste is generated, and the building materialswith low price and free of harmful gas emission can be generated.

Description

technical field [0001] The invention relates to a treatment method for harmless solid waste, belonging to the technical field of waste treatment. Background technique [0002] Since a considerable amount of non-recyclable waste is generated every day, considerable costs are incurred annually for the disposal of the waste. Some waste materials, including such as lumber waste, polystyrene foam, various cellulose, automobile tires and plastics, are processed by incinerators, which will generate secondary waste, and the treatment of secondary waste will cost a lot of money. To address this problem, the prior art majority of methods for converting many innocuous solid waste bodies into useful products is to incorporate organic compounds, such as formaldehyde, in a polymeric binder. However, organic adhesives have burning problems during storage and release toxic gases, which are harmful to human health. Contents of the invention [0003] In order to overcome the shortcomings ...
