The invention provides an instant type liquid treating device which comprises a housing with an inlet and an outlet connected by a passage for passing a liquid medium through the device. The device further comprises at least one set of cooperating separate conductive faces connectable to an AC-power supply and directly exposed to each other in the passage such that the liquid medium can be treated by way of its own electrical resistance between the faces. A control is provided to facilitate relative movement of the faces.

The invention discloses a deicing and snow melting system utilizing terrestrial heat in a tunnel. The system comprises a heat pump unit, a heat supply pipe and heat exchange tubes, wherein the heat supply pipe and the heat exchange tubes are respectively communicated with the heat pump unit so as to form two circulating pipeline independent from each other; fluid in the heat supply pipe and the heat exchange tubes provides circulating power by virtue of the heat pump unit, and heat exchange is performed by virtue of the heat pump unit. According to the deicing and snow melting system utilizing terrestrial heat in the tunnel disclosed by the invention, rich geothermal resources in a high-temperature geothermal area can be utilized, and the terrestrial heat energy in the tunnel is transferred to the ground by virtue of the pipeline, so that the aims of actively melting snow and deicing are achieved. The snows and ice on the road surface in spring and winter can be eliminated, the road riding safety problem is improved, the asphalt pavement service quality is improved, the traffic accident rate and economic losses are reduced, the life and property safety of the masses can be protected, the service performance of the asphalt pavement can be maintained, the service life is prolonged, the environmental hazards caused by use of chlorine deicers are reduced, good economical benefits are achieved, and the renewable and sustainable energy, namely, the terrestrial heat energy is reasonably used.

A device for digesting sludge anaerobically, comprising a digesting tank (100) having an upper region (104) and a lower region (105), and a reaction chamber (107) for converting raw sludge into matured sludge, an inlet (112) for introducing sludge (109) into the digesting tank, at least one transfer pipe (120) for channelling sludge from the lower region of the digesting tank to the upper region of the digesting tank, said at least one transfer pipe being arranged within the digesting tank and having at least a part of its length thereof arranged within the reaction chamber so that at least one transfer pipe is in contact with sludge moving through the reaction chamber, thereby resulting in heat transfer from sludge moving in at least on transfer pipe to sludge in the reaction chamber, and an outlet (114); arranged at the lower region of the digesting tank for discharging matured sludge (116) from the digesting tank.

The invention provides a production method of fortuneana wine. The production method comprises the following steps: sequentially performing impurity removal, washing, breaking, fermentation, mixing, refine precipitation and refine filtering on wild pyracantha fortuneana fruit which is used as a raw material, so as to finally obtain the finished product fortuneana wine. Compared with the prior art, vitamin C, ammonia acid, SOD (Superoxide Dismutase), VP and multiple vitamins of the wild fruit are maximally preserved and protected by virtue of a fortuneana wine production method, the novel fortuneana wine is successfully produced by adopting liquid, low-temperature and multi-time fermentation technology; moreover, the economic income of the fortuneana wine is high, and the social benefit is good.
