Shandong North China Paper Sludge "Change Face" Ecological Fertilizer

The waste sludge produced in the paper making process of the Sludge Fertilizer Plant at the North China Paper Co., Ltd. in Dezhou, Texas, has been processed through a single lane of production lines. With a strict ratio and other raw materials, it can be turned into tiny particles. “This is a kind of eco-fertilizer welcomed by farmers. The sludge turns face ecological fertilizer. This is the result of the quality supervision department helping us to develop our circular economy.” said the workshop technician of the company.

In recent years, the Bureau of Quality Supervision of Dezhou Municipality has established a foothold in its functions, exerted its technological advantages, helped large polluters and energy users to make a major contribution to the development of recycling economy, and made the development of recycling economy an important measure for transforming the mode of economic growth and energy conservation and emission reduction. First of all, focus on the waste generated in production.

According to statistics, in the process of papermaking, the North China Paper Industry Co., Ltd. of Dezhou produced 30 tons of waste sludge every day, and it was necessary to clear and transport the hired vehicles every few days. The quality supervision department organized the relevant experts and the company's technical staff to set up a research team to analyze and analyze the waste water and waste generated by the company, to understand the ingredients in detail, and to find out the reusable value. In laboratory tests, they found that these sludges contain about 30% organic matter and can use organic matter to produce organic fertilizers. After passing the feasibility study, the company invested 5 million yuan to purchase production equipment, established a sludge-fertilizer plant, and fully utilized the fermentation, rotten microbes and other raw materials in the sludge after exposure, mixing, heating, and refining. A series of rigorous processes to produce organic ecological fertilizers. According to reports, this fertilizer contains sufficient nitrogen, phosphorus, potassium and other organic substances, can effectively promote the growth of crops, but without any toxic side effects on the soil, is a veritable ecological fertilizer.

At the same time, it helps companies to carry out technological transformation of various production processes in order to reduce run, run, drip and leakage, save energy, and reduce production costs. The energy conservation and consumption reduction service team established by the quality supervision department started from the subtleties to guide and urge enterprises to strengthen the basic work of energy measurement, and improve the company's measurement management and measurement detection system. According to the requirements of the “Guidelines for the Use of Measuring Instruments for Energy-consuming Units”, enterprises should be assisted in improving the allocation of energy measuring instruments, ensuring the traceability of quantities, helping enterprises to do energy-saving and efficiency-improving work, guiding enterprises to continuously improve energy measurement and detection capabilities, and improving energy measurement instruments. Equipped rate and control level of energy measurement and inspection process; Help enterprises establish a scientific and reasonable measurement management system according to ISO10012 "Measurement Management System" standard, so that the company's energy management, safety management, operation management and environmental testing management level Reach a higher level.

Texas North China Paper Co., Ltd. helped transform the water treatment system of the papermaking process under the help of the quality supervision department, reducing water consumption per ton of paper from 300 cubic meters per ton to 7 cubic meters per ton, saving more than 20 million water a year. Cubic meters, COD emission indicators from the original 3000 to 4000 mg / l, the annual reduction of the paper industry characteristic pollutants of 2700 tons.
