Embodiment 1

[0024] The Enteromorpha used was taken from the No. 1 Beach in Qingdao. The Enteromorpha was washed, dried in an oven at 70°C, pulverized into powder in a magnetic pulverizer, and passed through a 100-mesh sieve to obtain a dry sample of Enteromorpha. Mix the dry sample of Enteromorpha and deionized water at a mass ratio of 1:75, stir and extract in a constant temperature water bath at 90°C for 4 hours, and centrifuge the extracted solution for 20 minutes at a speed of 5000 r / min in a high-speed centrifuge. After taking the supernatant and adding an equal volume of deionized water to dilute, it is the Enteromorpha extract.

[0025] Add the inorganic coagulant aluminum sulfate and Enteromorpha extract to the water sample to be treated at an interval of 30 seconds for coagulation treatment. The amount of Enteromorpha extract is 0.1ml / L water, and the dosage of the inorganic coagulant is based on the mass of Al 1-11mg / L water.

Embodiment 2

[0036]The Enteromorpha used was taken from the No. 1 Beach in Qingdao. The Enteromorpha was washed, dried in an oven at 70°C, pulverized into powder in a magnetic pulverizer, and passed through a 100-mesh sieve to obtain a dry sample of Enteromorpha. Mix the dry sample of Enteromorpha and deionized water at a mass ratio of 1:70, stir and extract in a constant temperature water bath at 85°C for 4 hours, and centrifuge the extracted solution for 20 minutes at a speed of 4500r / min in a high-speed centrifuge. After taking the supernatant and adding an equal volume of deionized water to dilute, it is the Enteromorpha extract.

[0037] The inorganic coagulant ferric chloride and the extract of Enteromorpha enteromorpha were added to the water sample to be treated successively at an interval of 30 seconds for coagulation treatment.

[0038] The inorganic coagulant-enteromorpha compound water treatment agent of the above-mentioned embodiment 2 was applied in the coagulation treatment ...

Abstract

The invention relates to an inorganic coagulant-enteromorpha compound water treatment agent and a preparation method thereof. According to the preparation method of the inorganic coagulant-enteromorpha compound water treatment agent, catastrophic algae-enteromorpha is taken as a raw material, an enteromorpha extract is prepared by adopting an extraction technology; and in a process of water treatment, an inorganic coagulant and the enteromorpha extract are used through successively medicating at an interval of 30-50 seconds. The inorganic coagulant-enteromorpha compound water treatment agent integrates the advantages that the molecular weight of the enteromorpha is high and the enteromorpha has strong adsorption bridging capability on colloidal substances, and the inorganic coagulant has a wide optimal medicating range, a good flocculation effect and a wide range of application, so that the inorganic coagulant-enteromorpha compound water treatment agent has the advantages of simple and fast and economical production technology, and wide range of application. Meanwhile, a new thought is provided for the technology for reusing the catastrophic algae-enteromorpha.

Description

technical field [0001] The invention relates to an inorganic coagulant-enteromorpha compound water treatment agent and a preparation method thereof, belonging to the technical field of environmental chemical water treatment agents. Background technique [0002] The coagulation process is an indispensable pre-unit operation technology in many processes of water supply and wastewater treatment. The coagulation treatment effect often determines the operating conditions, treatment costs and final effluent water quality of subsequent processes. With the increasing shortage of water resources and water pollution in recent years, how to improve the quality and effect of the existing traditional coagulation technology has become a research hotspot in the field of water treatment. In particular, the development of new, efficient, safe and non-toxic coagulants will largely determine the progress of water treatment technology, the overall operating costs of sewage plants and the qualit...
