[0053] Example

[0054] The high-efficiency sewage treatment agent in a low-temperature environment of the present invention includes, in terms of weight percentage: 45% polyaluminum ferric silicate, 30% bentonite, 20% zeolite powder, and 5% diatomite. The agent can be directly put into domestic sewage for use, and the applicable pH range is 5.0-9.0. The treatment effect is not affected by low temperature conditions, and it is easy to follow-up filtration treatment.

[0055] Such as figure 2 As shown, the front-end biochemical system of the treatment system when the agent of the present invention is used to treat sewage includes: a regulating tank, an anoxic tank, a first aerobic tank, and a second aerobic tank. The oxygen tank and the second aerobic tank are connected and connected in turn, the bottom of the adjustment tank is provided with a lift pump, the first aerobic tank and the second aerobic tank are equipped with microporous aerators, and pass through the The aeration pi...

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...
