Efficient sewage treatment agent in low-temperature environment and method for treating sewage by using same

Abstract

The invention discloses an efficient sewage treatment agent in a low-temperature environment and a method for treating sewage by using the efficient sewage treatment agent, and belongs to the technical field of sewage treatment. The efficient sewage treatment agent in the low-temperature environment is prepared from the following components in percentage by weight: 43.8 percent to 46.5 percent ofpolysilicate aluminum ferric, 28.7 percent to 30.6 percent of bentonite, 19.3 percent to 20.9 percent of zeolite powder and 4.9 percent to 5.4 percent of diatomite. The sewage treatment effect of thesewage treatment agent is not influenced by low-temperature conditions, the treatment process is simple and easy to operate, and the final domestic sewage treatment effluent can stably reach the first-grade B standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a high-efficiency sewage treatment agent in a low-temperature environment and a method for treating sewage with the same. Background technique [0002] The Yellow River is the mother river of the Chinese nation. To manage the Yellow River, the most important thing is to protect and manage it. The Yellow River ecosystem is an organic whole. It is necessary to fully consider the differences between the upper, middle and lower reaches, and promote the implementation of a number of major ecological protection restoration and construction projects. In the Yellow River Basin, there are large seasonal differences and great temperature differences. The Heyuan area above Jiuzhi County in Qinghai Province on the upper reaches of the Yellow River is "winter all year round"; The Longmen interval is "long in winter (six or seven months) and short in summer (one or two mo...

Problems solved by technology

[0004] Facing the low temperature in winter, sewage treatment must ensure that the effluent meets the standard. The commonly used methods include: establishing an insulation system to increase the temperature of sewage, increasing the concentration of sludge, prolonging the sedimentation time, increasing the amount of aeration, etc., but these methods have poor effects or cost. high disadvantage
