Provided is a novel carbonization treatment method for carbonizing a biomass material containing a large amount of water at an extremely low temperature, and a method for producing carbonized biomass. A water-containing biomass material is carbonized while maintaining the biomass material under treatment conditions including an oxygen-containing atmosphere and a temperature range of 70° C. or greater and less than 100° C., without a drying step for removing or reducing the water forcibly. At this time, preferably the water content (percentage) of the biomass material at the start of carbonization while maintained under the treatment conditions is within a range of 40 to 80% inclusive, and preferably the biomass material is thus maintained for two weeks or longer. Further, as the biomass material, one material or a mixture of two or more materials selected from waste biomass materials and plant (cultivated crop) biomass materials such as food waste, livestock excrement, agricultural waste, marine waste, and forest waste, can be applied.

Contaminants can be removed from liquids in accordance with systems and methods herein. One exemplary method can involve introducing an input liquid into a pressurized chamber. The method can also involve oxidizing an organic or inorganic contaminant in the input liquid by heating the input liquid in the pressurized chamber, to create an output liquid that has less of the organic or inorganic contaminant than is present in the input liquid. And the method can involve outputting the output liquid from the pressurized chamber.

A swimming pool chemical dispenser includes a main body having an accommodating cavity formed therein for storing chemical tablets, an upper cover which covers the upper opening of the main body, and a tablet clamp having a clamping end penetrating downward through the upper cover and abutting against the chemical tablets. The tablet clamp is provided with scales. The tablet clamp descends along with the dissolution of the chemical tablets and the amount of residual chemical tablets can be visually and reliably determined from the scales on the tablet clamp for timely refill. The tablet clamp is placed on the main body, thus making it convenient for the user to replace the chemical tablets bare-handed without touching the chemical tablets, which is much safer and more environmentally friendly.
