Abstract

The invention discloses an efficient wastewater treatment agent which comprises the following components: 40-60 parts of inorganic natural mineral substances, 20-40 parts of inorganic sulfate, 10-30 parts of inorganic carbonate or alkali, and 1-5 parts of inorganic polymeric sulfate. The efficient wastewater treatment agent is neutral, the application of the efficient wastewater treatment agent does not affect the pH value of an aqueous solution, and the application of the efficient wastewater treatment agent is not affected by the pH value of wastewater required to be treated, therefore, the efficient wastewater treatment agent is easy to use; indexes of SS (suspended solids), COD (chemical oxygen demand), BOD (biological oxygen demand), total phosphorus, total nitrogen, and the like in eutrophic water can be greatly reduced, and settled flocculates are coagulated, changed from hydrophilicity to hydrophobicity, and not dissolved in water again.

Description

technical field [0001] The invention relates to the field of sewage purification treatment, in particular to a high-efficiency sewage treatment agent and a use method thereof. Background technique [0002] In the process of tunnel cleaning, river construction, etc., a large amount of sewage, mud, etc. will inevitably be produced. If the sewage and mud are directly discharged at the construction site, it will cause adverse effects on the environment. In foreign countries, these sewage are usually recovered by tanker trucks and brought back to the city's sewage treatment plants for professional sewage treatment before they can be discharged. Doing this will not only require a lot of time, delay the construction period, but also require a large amount of sewage treatment costs. In the above-mentioned traditional treatment methods, a considerable part of the time is used to transport the sewage to the sewage treatment plant, and the construction efficiency is very low. If you...
