Solar water purifier for lakes and water purification method thereof

The invention mainly discloses a solar water purifier for lakes and a water purification method thereof. According to the technical scheme, the solar water purifier comprises a main body, a purification system, an energy system, a drive unit, a lighting device and a fixation device. The energy system comprises a solar cell panel, a storage battery and a charging panel. An oxygenation chamber, a disinfection chamber and a purifying chamber are arranged inside the main body. An ozone generator, an air compressor, a bubble generator and an aerator pipe are disposed inside the oxygenation chamber. A drug blending tank is arranged inside the disinfection chamber. A purifier is disposed inside the purifying chamber. When the device operates, installation and pilot run of the device are firstly carried out. After successful pilot run, the device is put into a lake. By mobile positioning of the drive unit, a water body undergoes disinfection, oxygenation and purification. The energy system provides energy. Thus, energy is self-sufficient. The solar water purifier has a simple structure, is low-cost and clean. By various purification methods, purification efficiency is high. By the floating and stationary combined design, position of the device can be controlled freely. Thus, repair rate of water body is high. The solar water purifier is easy to operate.

Optical reflector for reducing radiation heat transfer to hot engine parts

A high temperature gas turbine component for use in the gas flow path that comprises a specular optical reflector coating system. A thin specular optical reflector coating system is applied to the gas flow path of the component, that is, the surface of the component that forms a boundary for hot combustion gases. The component typically includes a thermal barrier coating overlying the high temperature metallic component that permits the component to operate at elevated temperatures. The thermal barrier coating must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path. The thin reflector coating system comprises a thin high temperature and corrosion resistant refractory stabilizing layer, which is applied over a thin reflective metal layer, which is applied over a thin high temperature and corrosion resistant refractory sealing layer. The coating system is applied over the polished thermal barrier coating by a process that can adequately adhere the reflector to the polished surface without increasing the roughness of the surface. The coating system reflects radiation back into the hot gas flow path or into the atmosphere. The reflected radiation is not focused onto any other hardware component. The design of the component is such that the radiation is returned to the gas flow path or sent to the atmosphere rather than absorbed into a component that only serves to increase the temperature of such a component.

Soil body repairing method based on soil gas-phase extraction and underground water gas injection

The invention discloses a soil body repairing method based on soil gas-phase extraction and underground water gas injection. The repairing method comprises the following steps: a gas injection well and an extraction well are paved by slotting and ditching; each of the gas injection well and the extraction well adopts a combined structure of a vertical well and a transverse well; the transverse well of the gas injection well is paved on soil of saturated zone under a contaminated region and the transverse well of the extraction well is paved on soil of non-saturated zone above the contaminated region; then grooves are backfilled and small holes are uniformly formed in the transverse wells; the gas injection well and the extraction well are connected with an underground water gas injection system arranged under the ground and a soil gas-phase extraction system; then the soil gas-phase extraction system is started to extract gas in the contaminated region by the transverse well of the extraction well; meanwhile, the underground water gas injection system is started and air is conveyed into the contaminated region by the transverse well of the gas injection well, so that a soil body with pollutants is repaired. The soil body repairing method has the advantages that the polluted soil body has strong air circulation efficiency and the repairing efficiency of the contaminated region can be accelerated; and the soil body repairing method is suitable for repairing a large area of soil polluted by VOC.

Method for reducing cadmium pollution to soil by planting edible amaranth

The invention discloses a method for reducing cadmium pollution to soil by planting edible amaranth. Remediation plants are planted in cadmium-polluted soil, a mixture of a beneficial bacterium agent and a humified straw solution is poured into the cadmium-polluted soil according to the ratio that water-holding capacity of the soil accounts for 60%-70% of the field capacity in a remediation period, wherein the weight ratio of the beneficial bacterium agent to the humified straw solution is 1 to 1, and the whole remediation plants are moved away from the cadmium-polluted soil at the end of the remediation period. On the premise that the edible amaranth is used as a biomass material, when the edible amaranth is used for remediating the cadmium-polluted soil, the activation induction effect of the beneficial bacterium agent and the humified straw solution is achieved, so that the biological effectiveness of cadmium is improved, the absorption and enrichment of the plants to the cadmium are promoted, and the phytoremediation rate of the soil polluted by the cadmium is increased; and in addition, the beneficial bacteria agent and the humified straw solution can promote the mass addition of the overground parts, the stem leaves and the dry matter of the root system of the edible amaranth, so that long-term goals of restoring land productivity and promoting regional landscape harmony, ecological balance and sustainable development are ultimately achieved.

Efficient image restoration method based on alternating direction method

The invention discloses an efficient image restoration method based on an alternating direction method. The efficient image restoration method based on the alternating direction method includes: translating image restoration problems into low rank matrix complement problems; further dividing each low rank matrix into a plurality of partitioned matrixes by decomposing an original image into three low rank matrixes according to R/G/B channels; complementing each partitioned matrix; combining all the partitioned matrixes after being complemented so as to obtain corresponding complement matrixes; further obtaining a repaired image according an combination of the complement matrixes. The efficient image restoration method based on the alternating direction method facilitates parallel processing through partitioning, complements each partitioned matrix by using the alternating direction method, greatly improves image restoration speed, can not damage overall relevance of the original matrixes due to the fact that the plurality of the partitioned matrixes are obtained by dividing the three low rank matrixes according to relative independence of the three low rank matrixes, and facilitates improvement of restoration accuracy. The efficient image restoration method based on the alternating direction method not only can be used for image restoration, but also can be used in fields of object removal, image noise reduction and the like.

A thin layer of the high temperature reflector the is applied over the polished thermal barrier coating by a process that can adequately adhere the reflector to the polished surface without increasing the roughness of the surface. The high temperature reflector can be applied to any surface aft of the compressor, such as on a centerbody. The surface reflects radiation back into the hot gas flow path or into the atmosphere. The reflected radiation is not focused onto any other hardware component. The design of the component is such that the radiation is returned to the gas flow path or sent to the atmosphere rather than absorbed into a component wall that only serves to increase the temperature of the wall.
