It comprises a disinfectant introduction pipe 11 for injecting a chlorine agent into the chamber 5, a water level controller 12, and a drain pipe 13.

In the conventional apparatus for purifying manure or the like in the conventional ship, manure or the like from a toilet is introduced into the pretreatment chamber 2 from the filth tube 6, large solids are removed by the filter 7, and small solids are Crushing is carried out by the turbulent action of the bubbles ejected from the aerating air pipe 8 and separated into a solid and a liquid, and the treatment liquid is introduced into the contact oxidation chamber 3 to form a contact oxidant 9 having a large number of wrinkles. The organic matter in the treatment liquid is decomposed into inorganic substances by the aerobic microorganisms formed in the form of a film, and then the treatment liquid is introduced into the precipitation separation chamber 4 to precipitate the solid portion in the treatment liquid. Only the portion is introduced into the treatment liquid chamber 5, and the treatment liquid is sterilized and stored with the chlorine agent introduced from the disinfectant introduction pipe 11, and the treatment liquid is desired in the treatment liquid chamber 5. When the amount is stored, the water level controller 12 Detects, were automatically discharged to sea via the discharge pipe 13.

  However, since the above-mentioned conventional apparatus for purifying manure, etc. uses a chlorinating agent, it is difficult to control the removal and adjustment of residual chlorine. In particular, the “Prevention of Marine Pollution” issued by the Ministry of Land, Infrastructure, Transport and Tourism in 2010. Both the amount of residual chlorine and the number of high-temperature resistant Escherichia coli groups stipulated in `` Ministerial Ordinance Revising Part of Ministerial Ordinance on Technical Standards for Equipment, Marine Pollution Prevention Emergency Measures Manual, and Air Pollution Prevention Inspection Equipment '' There is a drawback that it is difficult to remove within the reference value.

There is a great advantage that the treatment capacity (efficiency) can be improved, for example, TSS can be remarkably lowered by performing the purification treatment by the action of the microorganisms.

  Moreover, the effect of microorganism treatment can be remarkably improved by using a three-stage contact oxidizing material.

In addition, since Escherichia coli is sterilized without using a chlorinating agent, residual chlorine does not come out and issued by the Ministry of Land, Infrastructure, Transport and Tourism "Marine pollution prevention equipment, marine pollution prevention emergency measures manuals etc." It becomes easy to remove both the amount of residual chlorine and the number of high-temperature resistant coliforms specified in the “Ministerial Ordinance Revising a Part of the Ordinance on Technical Standards for Facilities to be Prevented and Inspected” within the standard value.

Further, by circulating the treatment liquid in the treatment liquid chamber 19 to the sterilization apparatus 15 again, the variation in the sterilization effect can be reduced.

The present invention can also be applied to domestic liquid waste such as disposer wastewater.
