The invention provides an intelligent paddy field surface shallow-water wetland system capable of preventing and controlling nitrogen and phosphorus loss. The system comprises a central control system, a pump station, an irrigation system, a paddy field and a water level regulating gate, wherein the central control system comprises a data acquisition and analysis module, a control base station and a signal receiver; the data acquisition and analysis module comprehensively analyzes water and fertilizer management and a growth stage of aquatic crops determines field surface water level, transmits the information to the pump station and the water level regulating gate, controls start and stop of a water pump at the pump station and regulates the water level of the water level regulating gate; the data acquisition and analysis module reduce the water level of the paddy field in advance before rainfall through combination with weather forecast, and the system produces passive drainage as little as possible; when active drainage is required, water retention time in the field is ensured not to be shorter than required time, so that flow out of a large amount of tail water containing high-concentration nitrogen and phosphorus can be avoided. By means of absorption and purification of nitrogen and phosphorus by the field, agricultural non-point pollutants are discharged out of the area to the smallest extent on the premise that stable and high yield of crops is guaranteed.

The invention relates to the field of products of sound insulation material, solves the problems in the prior art that the sound insulation material is poor in sound insulation effect, is incomprehensive in high and low frequency sound insulation, causes pollution and is easy to age, and provides an efficient sound insulation material and a manufacturing method thereof. The efficient sound insulation material includes a sound insulation layer, a sound absorption layer, and a bubble layer, wherein the bubble layer is located between the sound insulation layer and the sound absorption layer. The sound absorption layer is made of a sound insulation compound, and the sound insulation compound is prepared by raw materials of the following substances: a thermoplastic resin, inorganic fillers, and a foaming agent, wherein the inorganic fillers account for 15-80wt%, the foaming agent accounts for 5-15wt%, and the rest is the thermoplastic resin. In the efficient sound insulation material, the fillers with different particle diameters correspond to sound waves of different wave bands or frequencies, and thus consumption of sound energy of different frequencies is relatively comprehensive, and the sound insulation effect is good, so the sound insulation material is suitable for popularization and application.

The present invention relates to a stochastic production simulation method and application of a sending-end power system considering energy abandonment constraints. The stochastic production simulation method includes the following steps: 1) Obtaining the annual load curve, and removing all nuclear power plants from the annual load curve. Annual output curve to obtain the continuous load curve, and according to the annual load level, the continuous load curve is divided into three stages: base load, waist load and peak load; 2) establish an equivalent power function according to the continuous load curve; 3 ) Realize output control of thermal power units and hydroelectric units at different stages according to equivalent electricity; 4) Consider the quotation of clean energy and its energy abandonment constraints, dynamically adjust the output status of clean energy and thermal power units, and obtain random production simulation data of the power system . Compared with the prior art, the present invention considers that the discardable power generation capacity of clean energy such as solar energy and wind power can be used as a conventional power source to participate in power system peak regulation, so as to ensure the minimum pollution of the system to the environment.

The invention belongs to the field of reuse of urban and industrial waste resources, and specifically relates to a modified concrete brick containing sludge gasification and retort slag and a preparation method thereof. 15-25% cement, 10-15% water, 0.01-0.05% accelerator, and the ratio of powder and slag in the gasification and retort slag is (1-2):3. The preparation method is: dry the gasified dry distillation slag until the water content is ≤10%, pass it through a roller crusher, control the coarse particle size to 5-15mm, and then sieve the powder through a 3mm sieve, weigh cement, gas Distillation slag, accelerator and water are mixed uniformly; the mixture is poured into a mold and then pressed into shape, and then naturally cured after demoulding. The invention obtains sludge gasification dry distillation slag by drying, granulating and gasifying urban sludge, and uses it as a raw material for preparing modified concrete bricks, which is beneficial to environmental protection and reduces the production cost of factories.
