硫酸鐵屬于弱酸性聚合物藥劑，在廢水除磷處理時，工業葡萄糖在混凝土工程中用減水劑和緩凝劑。其減水、增塑、緩凝作用都很顯著，能夠大大前進混凝土的和易性，減少坍落度丟失，前進混凝土的后期強


度，作為緩凝劑可使初凝時間從幾小時延伸到幾天而無損強度。并且適用范圍廣，泵送混凝土、大流動性混凝土、大體積混凝土、高強度功能混凝土中均可使用。
葡萄糖粉能夠作水泥摻合劑：水泥中添加必定數量葡萄糖粉后，可添加混凝土的可塑性和強度，且有阻滯作用，即推遲混凝土的開始與終究凝聚時期，例如添加0.15%的葡萄糖酸鈉，可將混凝土的初凝聚時間延伸10倍以上，也就是將混凝土的可塑時間從幾小時延伸至幾天，而不影響其牢度。Industrial glucose is used as water reducer and retarder in concrete engineering. Its water reducing, plasticizing and retarding effects are remarkable. It can greatly advance the workability of concrete, reduce the loss of slump and the late strength of forward concrete. As a retarder, the initial setting time can be extended from several hours to several days without damaging the strength. It can be used in pumping concrete, high fluidity concrete, mass concrete and high strength functional concrete.
Glucose powder can be used as cement admixture: When a certain amount of glucose powder is added to the cement, the plasticity and strength of concrete can be added, which can retard the beginning and final condensation period of concrete. For example, adding 0.15% sodium gluconate can extend the initial condensation time of concrete by more than 10 times, that is to say, it can delay the beginning and final condensation period of concrete. The plasticity time of concrete is extended from several hours to several days without affecting its fastness.

That is to say, delaying the beginning and final cohesion period of concrete, such as adding 0.15% glucose powder, can extend the initial cohesion time of concrete by more than 10 times, that is to say, delaying the plasticity time of concrete from several hours. Extend to a few days without affecting its fastness. Plasticity and delaying the start of condensation time are very important problems in concrete work. For example, in high temperature season construction and large-scale engineering work, delaying the start of condensation time is a difficult problem, and glucose powder can solve this problem satisfactorily. It is difficult to bond oil wells at other high temperatures. The concrete added with glucose powder can be plastic in a few hours at 170 C, so it can solve the above problems satisfactorily. Therefore, as a cement admixture, glucose powder has been used in many important construction projects abroad, such as many bridges in the Middle East. However, the use of sodium cellulose sulfonate in this field is not very extensive in our country. It is said that sodium cellulose sulfonate is extracted from papermaking wastewater, and its effect is not comparable to that of glucose powder.

五、過多正電荷金屬沉積物吸附在菌膠團表面，減弱了胞外多糖的作用，使菌膠團絮凝性減弱，導致活性污泥絮團細小，不利于后期的壓泥；

六、污泥量增大，在廢水除磷處理中，當聚合硫酸鐵投加量太大時則會出現產泥量過高，這也是聚合硫酸鐵相對于微生物處理法應用于廢水除磷處理中的弊端，投加過量會使水中的金屬磷酸鹽更多，形成更多的污泥。

對于現在聚合硫酸鐵產品的用量，是需要通過小試得出比較合適的投加量，如果水質發生變化的話，就需要重新做小試倆確定投加量，這樣避免聚合硫酸鐵投加量過多而影響處理效果，河南安家凈環保是一家專業從事聚合硫酸鐵生產銷售的廠家，歡迎前來咨詢合作。
