Project Name Measurement Gas Flowmeter and Measurement High Temperature and High Pressure Liquid Level Meter Industry Electronic Information Research Direction High Precision Flowmeter Main Business Field Metallurgical Power Chemical Core Technology Fiber Optic Level Meter Project Background Soil is an important material foundation for human production activities, and is an indispensable and difficult to regenerate natural resource. The quality of its management and use directly determines the success or failure of agricultural production and the rise and fall of human civilization. In the past 40 years, with the rapid development of social economy and intensive human activities, the area of soil pollution has been continuously expanding, and the harm has become increasingly serious, affecting the achievement of sustainable development strategic goals. Modern agriculture has changed the original state of nature. In pursuit of high yield and quality, it has led to the widespread use of fertilizers and pesticides, making soil pollution one of the major global environmental problems. China currently has approximately 130 million hectares of arable land, of which approximately 20 million hectares are subject to varying degrees of pollution. The ecological safety issues of agricultural products caused by soil pollution cannot be ignored. Due to the sink effect of soil on environmental pollution, toxic and harmful chemicals in soil are transmitted through the atmosphere and water bodies, posing a threat to the survival, reproduction, and safety of humans and animals. Soil pollution has become one of the main global environmental problems and has attracted high attention from countries around the world. Therefore, carrying out contaminated soil remediation activities is very important for blocking the entry of pollutants into the food chain, preventing harm to human health, and achieving sustainable socio-economic development. The expected annual production target is 50000 tons of biological fertilizers and soil amendments, which can solve the problem of 200000 mu of soil remediation and improvement area and reduce the amount of fertilizer application by 6000 tons. According to the market value, the humic acid is 300 yuan/ton, the average price of NPK, medium and trace elements is 1000 yuan/ton, and the functional bacteria is 25000 yuan/ton. Each ton of bio organic fertilizer production needs to add auxiliary materials to reach 180 yuan/ton. Crop specific fertilizers need to be adjusted based on the growth needs of different crops, and the formula should be adjusted on the basis of biological organic fertilizers. Other elements and bacterial agents should be added as needed. The average cost of crop specific fertilizers for different varieties is about 550 yuan/ton. Soil remediation agents need to be combined with soil testing and added with corresponding elements, with an average production cost of about 700 yuan/ton. The equipment (equipment/personnel/funds) has been customized and a cooperation agreement has been reached with the German LMS consulting company. However, due to the epidemic, the factory has not yet arrived and the funds have been in place.
