Efficient sewage treatment agent based on xanthan gum and preparation method of efficient sewage treatment agent

Abstract

The invention discloses an efficient sewage treatment agent based on xanthan gum and a preparation method of the efficient sewage treatment agent. The efficient sewage treatment agent is prepared by the xanthan gum, sepiolite powder, palygorskite, humic acid, sodium silicate, activated carbon, carboxymethyl cellulose, cassava flour, calcium oxide, potassium persulfate, ethyoxyl siloxane and polyethylene glycol. The preparation method includes: dissolving the polyethylene glycol, mixing with the xanthan gum, the palygorskite and the carboxymethyl cellulose, adding the sepiolite powder, the sodium silicate, the activated carbon and the ethyoxyl siloxane, evenly mixing, adding an aqueous solution obtained after the calcium oxide is dissolved, adding the humid acid for reaction, mixing with the cassava flour and the potassium persulfate after processing, and drying to obtain the efficient sewage treatment agent. The efficient sewage treatment agent and the preparation method thereof have the advantages that one of the main raw materials of the sewage treatment agent is the xanthan gum which is low in cost, wide in source and easy to obtain; the efficient sewage treatment agent is simple in preparation process and is used for treating city domestic sewage and industrial wastewater, the indexes of the treated wastewater are much lower than national standards, and an evident effect is achieved during the intermediate treatment of the sewage.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to a xanthan gum-based sewage treatment agent and a preparation method thereof. Background technique

[0002] Environmental protection directly affects the sustainable development of our national economy. In the past decades of economic development in our country, due to neglect of environmental protection in development, the current environmental pollution is very serious. Although a large number of control measures have been taken in recent years, the trend of further deterioration of the environment continues. In the annual sewage discharge in the country, only 10% of domestic sewage and 70% of industrial sewage are treated, and the effluent of about half of the industrial sewage treatment facilities does not meet the national discharge standards, and the rest of the untreated sewage is directly discharged into rivers and lakes As a result, my country's water environment has been...
