An environmental water resource recycling system of the invention comprises pluralities of drainpipes units, which includes pluralities of drainpipes engaged in pluralities of holder holes formed by coupled frame strips, and sealing lids covering the opening at one end of the drainpipes. An instant water-absorbing sand layer is applied on the soil layer exposed on the ground surface before inserting the lower end of the drainpipes held in the drainpipe unit into the sand layer. Concrete is poured onto the ground to be constructed such that the concrete can integrally cover the drainpipe units. The sealing lids can be removed from the openings on the upper end of the drainpipes after the concrete is solidified, thereby accomplishing a permeable paving and instantly draining the rain on the permeable paving to the sand layer and further to the underground for being recycled as water resource for further utilization.

The invention provides a composite ceramic structure comprising a porous ceramic and, bonded thereto by sintering, an ordinary fired material, and provide a process for producing the same. Further, it is intended to provide a novel product, such as tile or composite plant pot, constituted of this composite ceramic structure. Still further, it is intended to provide a wall surface structure that attains realization of a high added value of dry tile structure and is endowed with wall surface ornament and appearance beauty by plants, and that realizes energy saving through reduction of air conditioning load for buildings and other construction structure. There is provided a wall surface structure comprising a base wall surface and, detachable fitted thereto, a planar array of multiple tiles, wherein any parts devoid of tiles are fitted with pot-shaped tiles. In the wall surface structure, the tiles are arranged in lattice pattern lengthwise and crosswise to thereby form a tile surface, and the tiles are fitted above the corresponding parts devoid of tiles. Integer multiple of the width of pot-shaped tiles is made approximately equal to integer multiple of the crosswise width of tiles, and integer multiple of the height of pot-shaped tiles is made approximately equal to integer multiple of the lengthwise width of tiles, so as to effect fitting of pot-shaped tiles in the devoid parts. These tiles are composite tiles constituted of a composite ceramic structure comprising a fired material body and a porous ceramic body bonded to each other by sintering.

A multi-purpose pump system, comprising a thermodynamic unit (10), a main pneumatic positive displacement pump (20), a condenser (30), a circulating pneumatic positive displacement pump (40), a pipeline and a working medium therein, wherein a fluid inlet of the thermodynamic unit (10) is connected to a fluid outlet of the circulating pneumatic positive displacement pump (40), an air outlet of the thermodynamic unit (10) is connected to an air inlet of the main pneumatic positive displacement pump (20), an air outlet of the main pneumatic positive displacement pump (20) is connected to an air inlet of the condenser (30), a fluid outlet of the condenser (30) is connected to a fluid inlet of the circulating pneumatic positive displacement pump (40), an air inlet and an air outlet of the circulating pneumatic positive displacement pump (40) are respectively connected in parallel to the air inlet and air outlet of the main pneumatic positive displacement pump (20), or are connected in series between the air outlet of the main pneumatic positive displacement pump (20) and the air inlet of the condenser (30). The multi-purpose pump system can be used not only to concentrate and absorb medium and low grade heat so as to lower the temperature of our planet, but also to elevatedly transport, heat and filter a fluid. The multi-purpose pump system may employ a steam working medium, or an organic working medium; it may absorb the heat from a single heat source, or from multiple heat sources synchronously. Moreover, the multi-purpose pump system takes fewer steps to convert energy and can be built at a low cost.
