る。As a result of various studies, the inventor of the present invention has found that by adding special cement l-ill aluminum sulfate, which is made mainly from Portland cement and mixed with gypsum and slag, it has been found that it is particularly effective for organic soils, 1-11. %
We have discovered a coagulant that solidifies quickly when mixed with a certain amount.
本発明の凝固剤は前記公知技術の如く炭酸アルカリの配
合を必要としないものである。The coagulant of the present invention does not require the addition of alkali carbonate as in the prior art.
本発明の凝固剤の各成分については説明を加えるまでも
なく、通常の市販品を使用すれば足つ る 。There is no need to explain each component of the coagulant of the present invention, and it is sufficient to use ordinary commercially available products.

重量％程度で充分であるが、対象物に応じて５〜２０重
毫％の間で変動させればよい。The coagulant of the present invention exhibits its characteristics in sludge, sludge, etc. containing organic matter such as pulp waste liquid, sugars, petroleum decomposition substances, fats and oils, humic acid compounds, and decaying plants, with an organic content of 10% or more2. The mixing ratio (weight) of each component of the material is 5% of the total amount of gypsum and slag to Portland cement.
Below, it is usually about 30%. Appropriately, the ratio of gypsum to slag is approximately 1:1. For (5), +I3+ is 10
Although approximately % by weight is sufficient, it may be varied between 5 and 20% by weight depending on the object.
次に実施例をあげる。Next, an example will be given.
