High-efficiency sewage treating agent

Abstract

The invention discloses a high-efficiency sewage treating agent which comprises the following components in parts by weight: 15-80 parts of polysilicate aluminum ferric, 8-25 parts of active aluminum oxide, 8-18 parts of bleaching powder, 1-12 parts of organic phosphonium salt scale inhibitor, 2-10 parts of organic corrosion inhibitor and 2-12 parts of acetic acid. The high-efficiency sewage treating agent comprises a flocculant, an adsorbent, a bactericide, a scale inhibitor, a corrosion inhibitor and an antiscaling agent, and can comprehensively treat water. Compared with the prior art, the high-efficiency sewage treating agent has the advantages of wide treatment range, obviously higher removal ratio, favorable treatment effect, high removal ratio of suspended substances (up to 90% above), low raw material price, wide sources, low consumption, low cost and no toxicity or harm, and is easy to store; and the high-efficiency sewage treating agent is easy for sludge dewatering: since the material is unique, the floccule is compact, the precipitation speed is high, and the generated sludge can be easily dewatered.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an efficient sewage treatment agent. Background technique [0002] Sewage treatment is the process of making sewage meet the water quality requirements of a certain water body for drainage or reuse, and purifying it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic sub...

AI Technical Summary

Problems solved by technology

For cooling water systems that use water with higher hardness and alkalinity (hardness or alkalinity>200mg / L, hardness or alkalinity is calculated as CaCO3, the same below) as supplementary water, although there are many water treatment formulas, the main The problem is: 1) The selected components and their ratios do not reflect the synergy of the medicament; 2) The selection of components does not effectively reflect the requirements of comprehensive scale and corrosion inhibition and stability; 3) It should meet the requirements of In the trend of environmental protection, make the drainage as phosphorus-free or low-phosphorus as possible, and the chemicals are low-toxic or non-toxic; 4) The principle of low-volume and high-efficiency should be reflected

Although this formula solves the problem of unsatisfactory corrosion inhibition performance of sodium humate, the bactericidal effect is not very ideal
