With the rapid development of industry, large amounts of untreated industrial waste water and domestic sewage carried heavy metal pollutants below into the water body with enrichment in sediments. When environmental conditions change, enrichment of heavy metals in sludge may be released into the overlying water causing the overlying water quality standard. The agent on immobilization of heavy metals in sludge is to be an extremely promising remediation technology in order to reduce impact on the environment. This test selects Hydroxyapatite and Nano Hydroxyapatite as curing agent and puts it into heavy metal pollution by different proportion. The paper conducts the research of curing agent and optimizes the better one. The paper selected HAP as matrix and CaO and MgO as different additives and studied complex condition of heavy metals in sediment of curing effect. Also the paper conduct the static releases test for pollutants in cured sediment in order to provide technical support for contaminated sediment remediation of heavy metal.
