Abstract
The invention belongs to the technical field of waste water treating, in particular to a waste water treating agent. The waste water treating agent comprises, by weight, 20-30 parts of aluminum sulfate, 15-25 parts of ferric sulfate, 10-20 parts of bamboo vinegar, 15-25 parts of nanometer SiO2, 10-16 parts of tannin and 12-23 parts of polyacrylamide. The waste water treating agent has the advantages of being wide in removal range of harmful matter in waste water, capable of treating multiple harmful ingredients in the waste water and integrating advantages of multiple water treating medicament, stable in chemical property, capable of removing harmful matter such as formaldehyde, heavy metal, COD, phosphorus and other harmful particles in the waste water effectively, and suitable for municipal waste water and industrial waste water treating, and the water quality meets the discharge standard completely under the synergistic effect of organic combination of all the components.
Description
Technical field
The invention belongs to technical field of waste water processing, particularly a kind of waste water conditioner.
Background technology
Waste water (wastewater) refers to the general name of water and the runoff rainwater of discharging in resident's active procedure, and it comprises other useless water such as sanitary sewage, trade effluent and just rain footpath inflow sewer.Along with the fast development of China's chemical industry, various novel Chemicals are applied to all trades and professions, particularly in the heavily contaminated industry such as medicine, chemical industry, plating, printing and dyeing.Trade effluent flows directly into channel, rivers, lake pollution surface water, if toxicity causes the death of aquatic animals and plants even to disappear compared with conference, trade effluent also may penetrate into underground water, polluted underground water.If nearby residents adopts contaminated surface water or underground water as domestic water, can endanger healthy, severe one is dead.Trade effluent infiltrates soil, causes soil pollution, affects microbial growth in plants and soil.Some trade effluent also with unpleasant stench, polluted air.Hazardous and noxious substances in trade effluent can by vegeto-animal ingest and sorption residual in vivo, then arrived in human body by food chain, human body worked the mischief.Improving the quality of products, while quality also with day by day serious problem of environmental pollution, be mainly manifested in: Organic Pollutants in Wastewater concentration is high, Stability Analysis of Structures, biochemical are poor, common process is difficult to realize qualified discharge, and processing cost is high, reduce discharging to industry energy conservation and bring great pressure, this is the difficult problem that numerous domestic environmental worker and administrative authority pay close attention to, and domestic water process problem is also one of a great problem of wastewater treatment now.
For containing the trend of environmental degradation, country's implementation focus Water Basin Water Pollution control program, accelerates city wastewater treatment and reuse engineering construction, strict control industrial water pollution thing quantity discharged, attach most importance to papermaking, food brewing, chemical industry, textile printing and dyeing industry, strengthen and administer and transformation dynamics.But the current technology of waste water control of Environmental Protection in China industry is delayed, common technique and traditional Water Treatment Chemicals are difficult to produce a desired effect for solving the problem that in wastewater from chemical industry, concentration of narmful substance is high, toxicity is large, biodegradability is poor.The treatment agent for this reason studying a kind of effective process waste water becomes the task of top priority.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of exhaust gas treating agent, and this treatment agent can process the multiple objectionable constituent of waste water, and have the advantage of several Waste water treatment medicament concurrently, stable chemical nature, water treatment effect is remarkable.
For achieving the above object, the present invention adopts following technical scheme:
A kind of waste water conditioner, be made up of the raw material of following weight part:
For ensureing the superperformance of waste water conditioner, preferably, bamboo vinegar liquid relative density of the present invention is 1.02 ~ 1.06.When the present invention is with bamboo vinegar liquid process waste water, the removal effect of COD (chemical oxygen demand (COD)) can be made greatly to improve, and it is significant to the contribution of environmental protection.
Tannin of the present invention derives from persimmon.Tannin can adsorb heavy metal ions in wastewater, reduces heavy metal in waste water substances content.
The multinuclear high price complex ion that Tai-Ace S 150 in raw material of the present invention and Fe, Al ion in ferric sulfate are formed, main component is PAFS, these multinuclear high price complex ions are to electronegative phosphate radical, hydrogen phosphate, dihydrogen phosphate produces association adsorption, forms water-soluble low ionic associate.A large amount of oxyhydroxide flco precipitation is formed in hydrolytic process, there is very large specific surface area its inside, there is very strong adsorptive power, a part of free phosphorus, organophosphorus and compound thereof can be adsorbed, also can catch the phosphorus that volume sweeps a part of non-solubility by net during flco precipitation simultaneously, thus reach certain phosphor-removing effect, make full use of iron ion and aluminum ions mutual compensation performance, efficiently avoid the restriction of metal ion to water purification agent use range.
Nano-meter SiO_2
2have very strong adsorptive power, can adsorb the formaldehyde in waste water, not only there is physical adsorption in its PARA FORMALDEHYDE PRILLS(91,95), and has chemisorption, defines hydrogen bond or covalent linkage with formaldehyde, can be reduced the formaldehyde content in waste water.
Polyacrylamide in raw material of the present invention has good sedimentation flocculence, can reduce the friction between liquid, improves waste water treatment efficiency.
Preferably, waste water conditioner of the present invention, be made up of the raw material of following weight part:
Beneficial effect of the present invention is:
1, the present invention makes full use of iron ion and aluminum ions mutual compensation performance in Tai-Ace S 150 and ferric sulfate, efficiently avoid the restriction of metal ion to water purification agent use range, can effectively dephosphorization.
2, adopt the natural biological com-ponents such as bamboo vinegar liquid and tannin in the present invention, environmental protection, and remove the Be very effective of COD (chemical oxygen demand (COD)) and heavy metal.
3, the objectionable impurities scope removed in waste water of the present invention is wide, the multiple objectionable constituent of waste water can be processed, have the advantage of several Waste water treatment medicament concurrently, stable chemical nature, effectively can remove objectionable impurities in waste water as formaldehyde, heavy metal, COD, phosphorus and other deleterious particle thing thereof etc., under the synergy that its each component organically combines, water quality reaches emission standard completely, is applicable to municipal wastewater and Industrial Wastewater Treatment.
4, the time of process waste water of the present invention is short, and efficiency is high, when being used for processing waste water, only needing a settling tank, shortens sewage treatment technology process long, decrease floor space, save investment, be easy to operational management.
