preparation example Construction

[0029] The preparation method of described novel water pollution remediation agent comprises the following steps:

[0030] S1: Grinding the adsorbate into powder and passing through a 200-260 mesh sieve, adding bentonite, sodium chloride, lime, sodium carbonate, and a pH regulator in parts by weight, and adding deionized water to make a mixture A;

[0031] S2: Add trimethylcyclopropylammonium chloride, sodium polyacrylate, benzyltriethylammonium chloride, sodium dodecylbenzenesulfonate, and chitosan to mixture A, stir well, and ultrasonically vibrate for 20- 25min, to obtain mixture B;

[0032]S3: Add polyferric chloride, polyaluminum trichloride, and polyethyleneimine to the mixture B in turn, stir and mix well, stir for 20-30min, then add deionized water to wash for 2-3 times, and then set the temperature at 100-110°C Drying is carried out under certain conditions to prepare a new type of water body pollution restoration agent. The addition of the polyferric trichloride, po...

Abstract

The invention discloses a novel water body pollution repairing agent and a preparation method thereof and belongs to the field of water pollution management. The novel water body pollution repairing agent is prepared from the following components: polyferric chloride, polyaluminum chloride, polyethylenimine, bentonite, sodium chloride, lime, an adsorption substance, sodium carbonate, a pH (Potential of Hydrogen) regulator, ammonium trimethylcyclopropyl chloride, sodium polyacrylate, benzyl triethyl ammonium chloride, sodium dodecylbenzene sulfonate and chitosan. The water body pollution repairing agent is prepared through the steps of mixing, stirring, drying and the like. According to the novel water body pollution repairing agent, SS (Suspended Solids), COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) of the water body pollution repairing agent is reduced by adopting a reinforcing system composed of the benzyl triethyl ammonium chloride, the sodium dodecylbenzene sulfonate and the chitosan.

Description

technical field [0001] The invention belongs to the field of water pollution control, and in particular relates to a novel water pollution restoration agent and a preparation method thereof. Background technique [0002] my country is a country with a shortage of water resources. The per capita water resources are only 1 / 4 of the world's, and the distribution of water resources is seriously uneven. How to alleviate the shortage of water resources and pollution has become an urgent problem. At present, there are three main types of heavy metal wastewater treatment methods in various countries in the world: the first type is the method of removing heavy metal ions in wastewater through chemical reactions, including neutralization precipitation method, sulfide precipitation method, ferrite co-precipitation method, chemical reduction method, Electrochemical reduction method and polymer heavy metal trapping agent method, etc. The second category is the method of adsorbing, conce...
