Description of the Related Art Electric power demand is increasing rapidly year by year due to the spread of home appliances, computers, air conditioners, etc. Especially, peak load in summer is on the increase, but there are many problems such as environmental conservation and difficulty in locating power plants. It is also in a difficult situation to reinforce. Under these circumstances, in recent years, as a method to store cold heat during the night and level peak power during the day by using surplus inexpensive night power, etc., the method of using ice storage has been mainly used in new commercial buildings. Is becoming more popular and expanding.

するというのがその基本である。In the conventional ice heat storage method, cold heat is supplied via an external heat source to a refrigerant or a heat storage material such as tap water filled in an ice heat storage tank having an adiabatic closed structure, and is cooled to below the ice temperature to perform a freezing process. By storing the cold energy in the ice state,
The basic idea is to melt the ice stored adiabatically and recover the cold heat when necessary.

It is becoming more and more recognized that the conservation of water resources is also an important initiative. With regard to the conservation of such water resources, in recent years, it has become possible to reuse wastewater as flush water for flush toilets and sprinkling water by performing wastewater treatment on a factory or company basis, or on a regional basis.
Similar water reuse efforts have begun in residential areas such as new condominiums and new housing complexes.

As a result, it has been attracting attention as a system that can save the trouble of disposing of garbage.

題があった。Further, in the above publication, there is almost no mention of separation of solid matter in wastewater including solid matter in wastewater such as garbage and sludge water. In the case of separating such a solid matter, a coagulation additive that requires concentration control is required, and therefore maintenance personnel are always required and incidental equipment such as a screen or a flotation device is required. In particular, dehydration of sludge has a problem that the system becomes complicated because the size of the components constituting the sludge is small and the sludge is easily clogged.

The purpose is to obtain a wastewater purification process that separates sludge solids from wastewater without additives.
