Abstract

The invention discloses a domestic sewage treatment agent. The domestic sewage treatment agent is prepared by the following raw materials, by weight: 55-70 parts of a nano-magnetic ceramic matieral, 6-9 parts of montmorillonite, 0.5-1.5 parts of active alpha-alumina, 8-11 parts of calcium silicon slag, 4-6 parts of polymerized aluminum trichloride, 4-9 parts of basic iron chloride, 2-3 parts of sodium silicofluoride, 15-25 parts of polyacrylamide, 0.5-1 part of magnesium aluminosilicate, 11-14 parts of sponge rock, and 5-10 parts of activated carbon. The invention also discloses a preparationmethod of the domestic sewage treatment agent. Compared with the prior art, the domestic sewage treatment agent of the invention can be fabricated into a general fast filter tank according to treatment water quantity and discharge requiremtns. The sewage treatment agent has high adsorption efficiency for total phosphorus in pollutants, is simple in operation, good in treatment effect and low in operation cost, the used raw materials are cheap and easily available, a part of the raw materials are waste residues, and the process has the advantages of universality, simple operation and high wastewater treatment efficiency and is suitable for large-scale industrial utilization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment agent and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy, the society is constantly progressing, and people's living standards are also constantly improving, and the ensuing environmental pollution problems are also becoming increasingly prominent. In particular, the water resources that human beings rely on for survival and development are facing great threats. In particular, the domestic sewage generated by people's daily activities has directly become a major problem in front of human beings. [0003] There are many kinds of domestic sewage treatment processes. Most of the sewage treatment processes cannot fully meet the discharge standards when treating domestic sewage. Therefore, it is necessary to add sewage treatment agents for advanced treatment. Most sewage treatment f...
