Description of the Related Art Conventionally, various dialysates such as bicarbonate-containing dialysate and glucose-containing dialysate have been used as a dialysate for a dialysis device. However, there is a problem that a precipitate such as the above deposits and toxic substances such as endotoxin increase. As a method for removing precipitates and toxic substances in the dialysis equipment piping, means for washing the piping with an aqueous solution of sodium hypochlorite or acetic acid is used. However, it is difficult to remove calcium carbonate deposited in the piping with an aqueous solution of sodium hypochlorite, and acetic acid removes calcium carbonate.For this purpose, it is necessary to use a concentration high enough to corrode the piping. However, there was a problem when each was used alone. Therefore, there is a detergent used by mixing these chemical substances, for example, a detergent obtained by mixing sodium hypochlorite and ethylenediaminetetraacetic acid with a surfactant, but when the pH becomes 5 or less, chlorine gas is generated. In addition, when organic substances are present, there is a problem that the disinfection is not sufficiently performed unless a cleaning agent having an effective chlorine amount 20 to 100 times that of a normal cleaning agent is used.

質と思われる有機物質が沈着する問題が発生した。DISCLOSURE OF THE INVENTION The present inventors have studied diligently to solve these problems, and decompose proteins, sugars and fats in pipes with acids and oxygen to separate these organic substances from the pipes. Considering the possibility, the dialysis equipment piping was washed after dialysis using an aqueous solution of peracetic acid. The aqueous solution of peracetic acid reacts with a chemical substance in the pipe to perform a disinfecting action. Even if peracetic acid is decomposed, it becomes harmless water and acetic acid, so wastewater treatment is easy. No harmful gas is generated even if the pH is 5 or less, and it can be used in a wide range of staphylococci, spores, Escherichia coli, mold, viruses, etc. Although it has the property of exhibiting a high sterilization effect, repeated washing of the dialysis equipment piping caused a problem that organic substances, which are considered to be proteins, were deposited on the outlet side of the piping.
