description The invention relates to the technical field of treatment of sewage rich in nitrogen and phosphorus, in particular to an agent for synchronous nitrogen and phosphorus removal and a preparation method thereof. The invention provides an agent for synchronous nitrogen and phosphorus removal. The agent for synchronous nitrogen and phosphorus removal is specifically prepared from modified bentonite, magnesium chloride, polyaluminum ferric chloride, quick lime and magnetic powder. The invention also provides a preparation method of the agent for synchronous nitrogen and phosphorus removal. The preparation method comprises the following specific steps: preparing modified bentonite from lanthanum oxide; and weighing raw materials, grinding the raw materials, carrying out uniform stirring and mixing, and performing sieving to obtain the agent for synchronous nitrogen and phosphorus removal. The agent for synchronous nitrogen and phosphorus removal overcomes the defect that nitrogen and phosphorus are difficult to remo
