preparation example Construction

[0020] The preparation method of the sewage treatment agent includes grinding bentonite and adsorbate into powder, mixing and stirring ferric chloride, polyacrylamide, sodium chloride, bentonite, adsorbate, cornstarch and sugar according to the weight ratio .

[0021] The sewage treatment agent has wide sources of raw materials and low cost. The selected ferric chloride is easily soluble in water, has excellent coagulation effect, good product stability, and good flocculation purification effect; the adsorbent can absorb suspended particles in sewage and particles that are not easily soluble in water; since the adsorbate includes sawdust , straw powder, activated carbon, and rice husk, among which activated carbon accounts for one-third of the total weight of the adsorbate, which has a stronger adsorption capacity; adding cornstarch and sugar to the sewage treatment agent can further improve the adsorption and flocculation capacity .

Embodiment 1

[0023] According to the parts by weight of each component, take respectively: 10 parts of ferric chloride, 5 parts of polyacrylamide, 10 parts of sodium chloride, 20 parts of bentonite, 10 parts of adsorbate, 10 parts of cornstarch and 3 parts of sugar.

[0024] Prepare the ingredients according to the weight parts, grind the bentonite and the adsorbate into powder, mix and stir ferric chloride, polyacrylamide, sodium chloride, bentonite, adsorbate, corn starch, and sugar according to the weight ratio .

Embodiment 2

[0026] According to the parts by weight of each component, take respectively: 12 parts of ferric trichloride, 7 parts of polyacrylamide, 12 parts of sodium chloride, 24 parts of bentonite, 12 parts of adsorbate, 12 parts of cornstarch and 4 parts of sugar.

[0027] Prepare the ingredients according to the weight parts, grind the bentonite and the adsorbate into powder, mix and stir ferric chloride, polyacrylamide, sodium chloride, bentonite, adsorbate, corn starch, and sugar according to the weight ratio .

Abstract

The invention relates to a sewage treatment agent and a preparation method. The sewage treatment agent is prepared from the following raw materials in parts by weight: 10-15 parts of ferric trichloride, 5-10 parts of polyacrylamide, 10-15 parts of sodium chloride, 20-35 parts of bentonite, 10-15 parts of adsorbate, 10-15 parts of corn starch and 3-8 parts of sugar. The preparation method comprises the following steps: preparing the components according to parts by weight, grinding the bentonite and the adsorbate into powder, and uniformly mixing and stirring the ferric trichloride, the polyacrylamide, the sodium chloride, the bentonite, the adsorbate, the corn starch and sugar according to parts by weight. The sewage treatment agent is high in sewage treatment speed and relatively thorough in sewage treatment; the treated sewage can reach an effluent standard.

Description

technical field [0001] The invention relates to a sewage treatment agent and a preparation method, belonging to the technical field of sewage purification treatment. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. From the point of view of sewage sources, sewage can be defined as discharges and groundwater from residential, institutional, commercial or industrial areas. Waste-laden liquid or water mixed with surface water, blizzards, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories. The first category: Industrial wastewater Sewage from manufacturing, mining and industrial production activities, including runoff live leachate from industrial or commercial storage, processing, and other wastewater that is not domestic sewa...
