Sewage treatment chemical agent

Abstract

The invention discloses a sewage treatment chemical agent. The sewage treatment chemical agent is prepared by uniformly mixing the following components in percentage by weight: 24%-27% of calcium oxide, 35%-38% of sulfur trioxide, 4%-7% of silica, 3.03% of aluminum oxide, 20%-24% of sodium carbonate, 3.5%-3.96% of a bridging agent, 0.1%-0.3% of iron oxide, 0.1-0.2% of magnesium oxide, 0.8%-1.57% of sodium oxide and the balance of additives. The sewage treatment chemical agent has the advantages of high sewage treatment efficiency, low application cost, wide application range and no toxicity and corrosion.

Description

technical field [0001] The invention relates to a sewage treatment technology, in particular to a fast, efficient and environment-friendly sewage treatment agent. Background technique [0002] As an essential resource, water has long been considered inexhaustible and inexhaustible. Driven by this view, the quality of the water environment is getting worse and worse, and the shortage of water resources is becoming more and more serious, bringing a series of ecological environmental problems that endanger survival and development. In the past two decades of reform and opening up, the cause of sewage treatment has achieved rapid development, but it still lags behind the needs of social development. According to statistics, 427 urban sewage treatment plants have been built nationwide, including 282 secondary treatment plants. The construction of these sewage treatment plants has greatly improved the treatment level of urban sewage, but the increase in treatment capacity still ...

AI Technical Summary

Problems solved by technology

The construction of these sewage treatment plants has greatly improved the treatment level of urban sewage, but the increase in treatment capacity still lags far behind the increase in sewage discharge, and the gap between the two is likely to widen further.

Moreover, the current typical secondary treatment methods, such as oxidation ditch process, CASS (Cyclic Activated Sludge System, cycle activated sludge process) process, etc., are cumbersome and have no advantages compared with sewage treatment chemicals in large-scale applications.

In addition, in some special industries, such as oilfield oily sewage, pharmaceutical wastewater, printing and dyeing wastewater, papermaking wastewater, etc., the sewage treatment chemicals used not only have poor treatment effect, slow sedimentation speed, high cost, but also have the possibility of secondary pollution
