The eye-catching feature of this device is that it is based on the intractable, high-concentration waste liquids rich in nitrogen and organic matter discharged from MSG, papermaking, and pharmaceutical companies as its basic raw materials, adding appropriate amounts of auxiliary materials according to proprietary formulas, and adopting improved sprays. Granulation dryer, the waste liquid into organic compound fertilizer.
“Construction of this 40,000-ton/year organic high-concentration waste water to produce a compound fertilizer plant has invested a total of 6 million yuan. The comprehensive cost for producing compound fertilizer using it is less than 700 yuan/ton, and the current price of compound fertilizer has reached 1400 yuan. According to this calculation, it will take less than one year to recover all the investment. Now that we have completed the environmental evaluation of the other two sets of equipment, we will prepare two more such production lines in the near future." Told reporters.
According to Chairman Xu Fangchun of Xuyang Group, they have now produced nearly 400 sets of spray granulation dryers with independent intellectual property rights for more than 50 domestic enterprises. The compound fertilizer process using this equipment as the core waste liquid has been produced. In the domestic MSG industry has been fully promoted. Based on this, the group has continued to tackle this technology by focusing on the wastewater generated by the paper and pharmaceutical industries. In 2007, the improved organic high-concentration waste liquid compound fertilizer technology has been applied to two papermaking and pharmaceutical companies in Shandong Quanlin Group and Hebei Shijiazhuang Pharmaceutical Group.
Liu Fangchun said that their next step is to promote the process in the paper industry and bio-pharmaceutical companies that use starch as a raw material to provide a practical route for the wastewater treatment of these highly polluting industries, enabling them to achieve large-scale industrialization. produce.
According to reports, in the papermaking process using plant fibers as raw materials, about 60% of raw materials such as lignin, polypentose, and other chemical raw materials and water will form papermaking black liquor. Xu Yang Group researchers found that paper, MSG, and some waste discharged from pharmaceutical companies are rich in lignin, hemicellulose, and xylose, nitrogen, phosphorus, and potassium, which are highly utilized in the fertilizer industry. It can be converted into organic compound fertilizer through scientific formula and special equipment processing. To this end, they jointly with the Chinese Academy of Agricultural Sciences, jointly developed the technology of producing compound fertilizers using waste liquids such as monosodium glutamate, paper and pharmaceuticals, and the core equipment is the spray granulation dryer produced by the Asahi Group.
High-concentration organic waste liquid turned into compound fertilizer
Into the dark brown high-concentration organic waste liquid, the output of the market is pretty good sales of organic compound fertilizer. To achieve this magical change is the spray granulation dryer produced by Shandong Xuyang Machinery Group. This was the scene that the reporter saw on March 14 at Deju Chemical Co., Ltd. in Jining City, Shandong Province.
