The invention discloses a multi-stage ecological sewage purification treatment device which comprises a water collection well, a primary sedimentation basin with a grating, a hydrolysis acidification basin, an ecological filtering tank and an artificial wetland, wherein all the treatment basins are communicated with one another; a filler layer is laid at the bottom of the ecological filtering tank; a foam plate is arranged on the upper part of the ecological filtering tank, and aquatic plants with strong roots are planted on the foam plate; the filler layer is formed by mixing more than two of large gravels, cobblestones and quartz sand; microorganisms are attached to the filler layer to form a microorganism film; the roots of the aquatic plants are buried into the filler layer. The multi-stage ecological sewage purification treatment device disclosed by the invention has a good sewage treatment effect and can treat sewage without power or other energy; the problems of high probability of blockage and large sludge amount of a conventional sewage facility are solved; furthermore, flowers can be cultivated and fishes can be bred as ornamentals, and economical benefits are achieved.

The invention discloses a blocking-proofing fast infiltration system, comprising an impervious wall, an infiltration bed, a permeability pipe, a water collecting pipe, a water distributing channel and a water distributing pipe, wherein, the infiltration bed is arranged in the impervious wall and is composed of a soil layer I, a packing layer I, a packing layer II and a soil layer II from the bottom to top sequentially; the permeability pipe is inserted in the infiltration bed and penetrates through the infiltration bed, and the upper end of the permeability pipe is higher than the top layer of the infiltration bed; the water collecting pipe is arranged at the bottom of the infiltration bed and a limestone layer with 1-3 cm of grain diameter is covered around the water collecting pipe. Thesewage treatment process comprises the following steps: the sewage is discharged into the water distributing pipe and is seeped out from infiltration holes on the water distributing pipe and is infiltrated into an infiltration channel, then by the infiltration effect of ground substance capillary pipes in the infiltration channel, the sewage is spread into mixed ground substances of each layers around sequentially, under the co-actions of ground substance, microorganism and plants, the sewage is purified; the sewage is collected by the water collecting pipe which is arranged at the bottom part of the infiltration bed and is discharged after the sewage is purified. The blocking-proofing fast infiltration system has the advantages of simple structure, low operating cost and the like and is proposed to be popularized and used in a large scale.

The invention discloses a cutting propagation method for jasmine. The method includes the following steps that 1, a cutting shoot is prepared, a jasmine root system without obvious germ infection or scars is selected as the cutting shoot, the diameter of the jasmine root system is larger than or equal to 2 mm, the cutting shoot is cut into a small segment with the length ranging from 4 cm to 10 cm, the upper end of the cutting shoot is cut into a flat opening, the lower end of the cutting shoot is cut into a 45-60-degree inclined opening, excessive or too long fibrous roots on the root system are sheared off, the length of the left fibrous root is not larger than 1 cm, and meanwhile disinfection is conducted; 2, the cutting shoot is treated; 3, cutting treatment is conducted. According to the cutting propagation method for jasmine, the cutting shoot selected for cutting is an abandoned root system generated by clipping or cutting-off or shaping in the jasmine transplanting, pot replacing and large land seedling updating processes, a new path is provided for jasmine cutting propagation, and maximum utilization of resources is achieved. The requirement of the cutting shoot for the maturity of the jasmine root system is low, root system materials can be available and used for cuttage at any time, and the influences of materials or seasons are low. Operation is convenient, and the cuttage survival rate is high.

The invention discloses a grounding module and a preparation method thereof, belonging to the technical field of electric power and communication equipment. The grounding module includes a metal pole core and a non-metallic conductive material wrapping the metal pole core. Calculated by mass percentage, the non-metallic conductive material is composed of 10-15% artificial graphite powder, 45-60% natural Composed of phosphorus flake graphite and 30-40% high-grade cement, the grounding module is less affected by the seasons, and has the characteristics of convenient installation, corrosion resistance, and reliable performance. The present invention also provides a preparation method of the grounding module, including batching, kneading, extrusion, pressure maintaining, maintenance and other processes. The method is easy to operate and low in cost.

The invention discloses a preparing method of artificial seeds of hemarthria compressa capable of increasing the rate of the emergence of artificial seeds. According to the preparing method, stipes of the hemarthria compressa is adopted. The preparing method comprises the following steps: firstly cleaning up the stipes and carrying out disinfection treatment, then preparing artificial endosperm in a semigel state, putting the stipes of the hemarthria compressa in the artificial endosperm, then absorbing a mixture of the artificial endosperm and the stipes by adopting a dropper, wherein one stipes is absorbed every time, then dropping the absorbed mixture into a CaCl2 solution for ion exchange treatment, forming shells on the surface of the stipes to form capsules after a certain time, taking out the capsules and rinsing the capsules by adopting sterile deionized water to obtain the artificial seeds of the hemarthria compressa. The artificial seeds of the hemarthria compressa prepared by the preparing method are high in rate of the emergence, high in breeding speed and high in survival rate. Preparing materials are easy to obtain, the entire preparing process is simple, the seasonal effect is low, and the cost is low. The preparing method is suitable for popularization and application in plant artificial seed production technologies.

The invention relates to a method for efficiently treating pig cultivation waste water and belongs to the technical field of treatment of pig cultivation waste water. The method comprises the following steps: building a filtering pool with a water inlet pump at the top, paving aeration pipes at the bottom, connecting the aeration pipes with an aeration machine outside the filtering pool, mounting microporous aeration heads on the aeration pipes, paving an ecological filter cake, arranging a water outlet above the aeration pipes, connecting the water outlet with a water outlet pipe, connecting the water outlet pipe with a cultivation pool with a water pumping machine, paving nutritional soil, arranging a stirrer in the middle of the nutritional soil, connecting the stirrer with a television, pouring pig cultivation waste water into the filtering pool, starting the aeration machine, turning on the television after the waste water enters the cultivation pool, closing a valve and turning off the television when the water level reaches certain height, removing plants after plants are planted for certain time, and pumping water in the cultivation pool to finish treatment on the pig cultivation waste water. According to the treatment method provided by the invention, the treatment effect is not influenced by season or temperature change, underground water is not polluted, energy consumption is low, the needed mechanical equipment is less, and the maintenance management quantity is small.
