The invention provides a treatment material for chemical wastewater. The treatment material for the chemical wastewater is prepared from the following raw materials in parts by weight: 6 to 11 parts of aluminium oxide, 8 to 14 parts of activated carbon, 3 to 9 parts of hexamine, 2 to 6 parts of camphor, 2 to 6 parts of soyabean protein, 5 to 7 parts of attapulgite, 3 to 9 parts of sodium dihydrogen phosphate, 2 to 7 parts of sodium lignin sulfonate, 4 to 7 parts of benzene sulfonic acid sodium salt, 1 to 5 parts of bagasse, 6 to 10 parts of maleic anhydride grafted polypropylene, 2 to 6 parts of nanometer-grade granular inorganic material, 2 to 7 parts of bentonite, 2 to 8 parts of barium carbonate, and 6 to 9 parts of sodium sulfate. The treatment material for the chemical wastewater has the beneficial effects that the heavy metal ion in water can be effectively neutralized, so that the water can be purified, and meanwhile, suspended matters can be absorbed well, and as a result, the water purifying purpose is reached.

The problem to be solved by the present invention is to provide: a method for producing a tablet, such as a carbonate-spring-type bath agent, which is so designed that a neutralization reaction can occur vigorously and efficiently in the inside of the tablet in spite of a fact that the pH value of an aqueous solution into which the tablet is dissolved is neutral, carbon dioxide gas bubbles having as small sizes as possible can be released continuously for a certain period of time and therefore a large portion of the generated carbon dioxide gas can be dissolved in water without dissipating the carbon dioxide gas to air to thereby increase the total concentration of carbon dioxide components in water, and the carbon dioxide gas that contacts with the skin can be converted into a bicarbonate ion readily due to the pH value of the aqueous solution so that the bicarbonate ion can be absorbed through the skin; and the tablet. The solution for the problem is a method for producing a tablet by carrying out compression molding in the presence of an organic acid in an amount of 1 / 10 to 1 / 3 of the amount of a bicarbonate salt (sodium bicarbonate or potassium bicarbonate) and polyethylene glycol in an amount of 1 / 100 to 1 / 5 of the amount of the bicarbonate salt, wherein the tablet is produced by compression molding in such a manner that an aqueous solution in which the tablet is dissolved can have a pH value of 5.5 to 8.5, the hardness of the tablet becomes 15 kg or more, and each of the diameter and the thickness direction of the tablet becomes 7 mm or more.

The present invention generally relates to a system for the decontamination of air wherein airborne particles and other pollutants are either neutralized and / or destroyed by ozone. The system generally comprises an access chamber for receiving the air to be decontaminated, an ozone generator generally fluidly connected to the access chamber, and at least one treatment chamber, in communication with the access chamber, in which ozone, present in high concentration, can effectively neutralize and / or destroy the airborne particles and / or the other pollutants contained in the air. The air decontamination system is typically used in cooperation with the ventilation system of a building.
