Problems solved by technology

[0002] There are several types of sewage flocculants commonly used: one can only flocculate the sewage in the sewage to precipitate the sewage in the water, but the color of the sewage cannot be removed at the same time; the other can only remove the color in the water, and It cannot remove the dirt in the water; there is another kind that can only remove heavy metals in the water
However, the dirt and color in the water cannot be removed at the same time. In addition to the above-mentioned shortcomings, the above types of sewage permanent flocculants also have the disadvantages of high cost, poor adaptability and inability to adapt to the use of sewage treatment in various industries.

Embodiment Construction

[0017] In a 2,000ml beaker, first mix 500ml of industrially pure hydrochloric acid with a concentration of 31.45% and 500ml of water, and then gradually add 110 gram of aluminum ash to make it react, and the addition is completed, and after the reaction temperature is stable, stop stirring and carry out static precipitation. When the solid-liquid layering is clear, filter the reaction solution with gauze once. After filtering, pour the filtered liquid into a clean beaker, and gradually add 0.5 ml of polyacrylamide (coagulant aid) under stirring until it is evenly stirred. The desired product is obtained—gray liquid sewage flocculant. The "sewage flocculant" prepared in this preferred embodiment has been proved by use: this product not only has the advantages of wide application range, low consumption, and low cost, but also has the advantages of When purifying sewage, it can also absorb heavy metals in the water while removing the color and flocculating the dirt in the water, ...

Abstract

The invention discloses a manufacturing method of effluent flocculant, which comprises the following steps: blending alcaine and aluminium ash (slag) or bauxite evenly according to proportion; sedimenting; separating; adding coagulant aid. The technique is convenient to operate, which adsorbs heavy metal in the water.

Description

technical field [0001] The invention belongs to a production method of a sewage treatment agent, more precisely a production method of a sewage flocculant. Background technique [0002] There are several types of sewage flocculants commonly used: one can only flocculate the dirt in the sewage to precipitate the sewage in the water, but the color of the sewage cannot be removed at the same time; the other can only remove the color in the water, and It cannot remove the dirt in the water; there is another kind that can only remove heavy metals in the water. But the dirt and color in the water cannot be removed at the same time. In addition to the above-mentioned shortcomings, the above types of sewage permanent flocculants also have the disadvantages of high cost, poor adaptability and inability to adapt to the use of sewage treatment in various industries. Contents of the invention [0003] The task of the present invention is to seek a kind of production method of the sew...
