Abstract

The invention discloses a sewage treating agent. The sewage treating agent is prepared from components in parts by weight as follows: 5-25 parts of polymeric aluminum chloride, 3-15 parts of bentonite, 5-12 parts of sodium polyacrylate, 0.3-2.3 parts of lignosulfonate, 0.5-2 parts of sodium sulfate and 10-30 parts of activated carbon. The bentonite is organic-inorganic modified bentonite, the lignosulfonate is an amphiprotic chelating agent based on lignosulfonate, the amphiprotic chelating agent is calcium lignosulphonate phosphonate quaternary ammonium salt modified product, and the activated carbon is nano copper and copper 8-hydroxyquinoline modified activated carbon. The sewage treating agent has the benefits that the sewage treating agent is low in treatment cost and has no toxicityor pollution, all components can have a synergistic effect, nitrogen, phosphorus, organic pollutants and heavy metal ions in sewage can be effectively removed, and the treated sewage can reach the discharge standard specified by the environmental protection agency. No pollutants are produced during preparation, no side effects are exerted on operators, the production cost is low, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent. Background technique [0002] Environmental protection is an important aspect of sustainable development. Environmental protection and sustainable use of resources are the prerequisites for social development. Water treatment among the five key points of global sustainable development has become an important factor in people's lives. With the development of economy, the improvement of productivity and technical level, more and more sewage is discharged, which not only has adverse effects on people's work, life and environment, but also directly endangers human health. Therefore, exploring effective new technologies for sewage treatment has become an important research field for environmental protection. Since the reform and opening up, my country's economy has developed rapidly, and the level of industrial and agricultural production and urbani...
