Synergistic resource utilization method for waste water and waste residues
The invention provides a synergistic resource utilization method for waste water and waste residues, and relates to the technical field of industrial waste water reutilization. The resource utilization method comprises the following steps: firstly, testing the concentration of sodium sulfate wastewater generated in the industrial wastewater zero discharge treatment process, and measuring the content of aluminum oxide and the content of silicon oxide in waste residues; secondly, according to the concentration of the sodium sulfate wastewater, calculating the amount of clear water added into the full-waste concrete so as to regulate and control the adding amount of dry-basis sodium sulfate, regulating the part with insufficient water in the preparation process with clear water, and converting sodium sulfate into albite and ettringite double salt minerals to obtain the full-waste concrete; and finally, the full-waste concrete is used for constructional engineering, mine filling engineering or concrete prefabricated parts. According to the cooperative treatment and recycling method for the sodium sulfate salt wastewater and the waste residues, all components in the wastewater and the waste residues can be safely and efficiently utilized, clear water is saved, the available range is wide, the technological process is simple, the utilization mode is low in cost and high in efficiency, and industrial large-scale production, popularization and application are facilitated.
本发明提供一种废水废渣协同资源化利用方法，涉及工业废水再利用的技术领域。所述资源化利用方法为：首先测试工业废水零排放处置工艺过程中产生的硫酸钠废水浓度，测定废渣中的氧化铝含量和氧化硅含量；其次依据硫酸钠废水浓度计算配入全废混凝土的清水量进而调控干基硫酸钠配入量，配制过程中水量不足部分以清水调节，硫酸钠转化为钠长石、钙矾石复盐矿物，得到全废混凝土；最后将全废混凝土用于建筑工程、矿井充填工程或者混凝土预制件。本发明采用的硫酸钠盐废水和废渣的协同处理再利用方法使得废水和废渣中的所有成分都能得到安全、高效利用，节省了清水，能够利用的范围较广，工艺流程简单，利用方式成本低、效率高，利于工业大规模生产和推广使用。
