The invention relates to a repair method of acid contaminated soil. The repair method comprises the following steps of detecting a pH value of the acid contaminated soil, uniformly spraying weakly alkaline liquid to the acid contaminated soil, standing for 2 to 4 h after the acid contaminated soil is soaked in the weakly alkaline liquid, and then turning over the acid contaminated soil; spraying the weakly alkaline liquid to the acid contaminated soil again after turnover, and standing for 2 to 4 h so as to obtain a soil mixture I; adding a soil conditioner to the soil mixture I, uniformly mixing the soil mixture I and the soil conditioner, and standing for 24 to 48 h so as to obtain a soil mixture II; adjusting the water content of the soil mixture II to 60 to 70%; and then putting earthworms, and culturing for 30 to 45 days, so that the acid contaminated soil is repaired. The repair method has a good repair effect on the acid contaminated soil, so that the acid contaminated soil canmeet the requirements of residential land, commercial land and industrial land; in addition, the whole repair cycle of the contaminated soil is short, and the efficiency is high.

The invention discloses a spatial layout optimization method for coastal zone sea reclamation. First, area sea reclamation suitability evaluation is carried out, and an appropriate reclamation area is selected; then, the sea reclamation potential of the appropriate reclamation area is evaluated; and finally, the economic feasibility of a sea reclamation project for land for commercial use, industrial land and residential land is evaluated. The beneficial effect lies in that the evaluation result is highly instructional to regional planning and project approval, and aiming at strong subjectivity of traditional sea reclamation evaluation, evaluation indicators are divided into descriptive, benefit-oriented, cost-oriented and moderate indicators according to the functions and characteristics and different methods of standardization are introduced to ensure the objectivity of evaluation results.

The invention discloses an electricity consumption data-based method for rapidly recognizing urban low-efficiency industrial lands. The method comprises the following steps of: collecting road trafficnetworks, lands, enterprises, power supply regions and monthly electricity consumption data of urban industrial land plaques; screening elementary data through development statuses and addresses; modifying default and abnormal elementary data through a variable coefficient method, land areas and monthly land average electricity consumption values; matching the elementary data through a high-definition satellite imagery and geographic coordinates; checking the elementary data through a topological relationship and the addresses; and recognizing the plaques, monthly land average electricity consumptions of which are lower than a national electricity consumption standard, so as to generate an urban low-efficiency industrial land recognition and distribution diagram. According to the method,urban low-efficiency industrial lands are recognized on the basis of industrial electricity consumption data, so as to evaluate whether the urban industrial land plaques are sufficiently utilized or not and whether the urban industrial land plaques have re-developing potentials or not, thereby realizing efficient and sustainable utilization of the urban industrial land plaques.

The invention discloses a method for analyzing industrial land benefits of a development area. The method comprises the steps of firstly, inputting a development area topographic map or an enterprise land distribution map to form a spatial database, and embedding various statistical data of all enterprise running conditions into the database through a certain association relationship; secondly, calculating each enterprise data, establishing sub-databases of land benefits on four aspects of space, economy, society and ecology, then comparing each item according to the latest specific index requirement proposed by the state for transformation development of a certain industry or the index requirement specified in the industry to judge whether the item meets the specified requirement, and calculating the difference from the specified index; and finally, outputting a comparison result in the form of a drawing and a format respectively, so as to provide a decision-making or research basis for a management or scientific research department. The method is convenient operate and accurate in analysis, and solves the problems of simple decision and insufficient scientific support on the aspect of land management in the transformation development process of the development area.

The invention discloses a configuration structure of a substation and distribution station in an alumina plant. The substation and distribution station is a left-right symmetrical structure, and the substation and distribution station is a three-story building with stairwells (9) at both ends; Two power distribution rooms (2) and one reactance room (7) are arranged in a square shape; the bottom layer of the two power distribution rooms (2) and one reactance room (7) is the cable sandwich room (1), and the The top floor of the electrical room (2) is the GIS switch station room (3), two transformer compartments (5) are arranged in front of the two power distribution rooms (2), and capacitors are respectively installed outside the two transformer compartments (5) Room (6), the top floor of the capacitor room (6) is provided with an isolating switch room (4). The invention changes the plane configuration of the existing substation and distribution station into a substation and distribution station with a three-story building structure. Under the condition of satisfying the electrical safety of the substation and distribution station, the occupied area of ​​the substation and distribution station is greatly reduced, and the problem of extremely tight industrial land is solved. It has good economic and social benefits.

The invention discloses a soil ecological restoration device for industrial land, which comprises a box body, a mixing unit and a liquid supply unit. The mechanism includes a rotating shaft, a mixing tube and a driving mechanism for driving the rotating shaft to rotate. The crushing mechanism includes a first installation shaft, a fan plate, a transmission gear, an inner ring gear, a second installation shaft and a crushing blade. The liquid supply unit includes Repair the liquid tank, pump body and liquid supply pipeline. This application is equipped with a mixing unit and a liquid supply unit. The fan plate lifts the soil at the bottom of the box and then throws it out. The soil on both sides is scattered and collided with each other. The re-beating is helpful for the crushing and mixing of the soil. The repair liquid enters the liquid supply pipeline through the pump body and then enters the rotating shaft and the mixing pipe. It is sprayed out from the liquid spray hole and mixed with the scattered soil. The mixing is more complete and uniform. Improved soil remediation efficiency.
