Abstract

The invention relates to the technical field of water environment management and in particular relates to an urban sewage purifying agent and application thereof. The urban sewage purifying agent is prepared from an agent A and an agent B, wherein the agent A and the agent B are prepared from the following substances in parts by mass respectively: the agent A: 0.1 to 30 parts of a hydration agent,0.1 to 45 parts of a flocculating agent and 0.1 to 40 parts of a peroxidant; the agent B: 0.1 to 6 parts of a microorganism preparation. According to the urban sewage purifying agent provided by theinvention, sewage can be effectively and completely purified by adopting a complex method of an oxidization method, a precipitation method, a microorganism degradation method and the like.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to an urban sewage purifying agent and an application method thereof. Background technique [0002] my country is a country with scarce water resources, the total amount is insufficient, the temporal and spatial distribution is uneven, and the pollution is relatively serious. There are many factors that cause the shortage of water resources in our country, such as the serious waste of water resources, the aggravation of water resource pollution, and the imperfect management system of water resources. my country's water resource pollution is also mainly manifested in the fact that rivers are continuously discharged into sewage, waste oil, waste liquid, chemicals and other pollutants, surface water and groundwater have been seriously polluted, rivers and ponds around towns are black and smelly Pollutants not only affect the appearance of the city and produce odor, ...
