Problems solved by technology

However, the current sewage treatment situation is not optimistic. Sewage treatment generally removes those metal ions existing in wastewater by adding reducing agents to wastewater without reducing heavy metal ions. Iron powder, etc. are used as reducing agents, which easily cause secondary pollution.

Abstract

The invention relates to a composite material for purifying water. The composite material is made of the following raw materials in parts by weight: 6-11 parts of anatase titanium dioxide, 8-12 parts of carboxymethyl methylcellulose, 3-9 parts of talcum powder, 6-10 parts of diatomite, 2-5 parts of palm oil, 2-7 parts of lauryl methacrylate, 1-5 parts of atractylodes, 4-9 parts of linear low-density polyethylene, 2-8 parts of potato straw powder, 1-5 parts of iron oxide, 8-14 parts of sodium dihydrogen phosphate, 1-3 parts of attapulgite and 5-11 parts of oyster shell powder. The composite material for purifying water disclosed by the invention plays the role of fast sedimentation, and can adsorb heavy metal ions in water without pollution to the water.

Description

technical field [0001] The invention relates to a composite material for water purification. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in China, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to take the construction of domestic sewage treatment facilities as a priority The important content of urban infrastructure is to be grasped, and it is a matter of urgency. However, the current sewage treatment situation is not optimistic. Sewage treatment generally removes those metal ions present in wastewater by adding reducing agents to wastewater without reducing heavy metal ions. Iron powder is used as reducing agent, which is easy to cause secondary pollution. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be ...
