Description

Printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs S126S5 Α7 Β7 V. Description of the invention (1) The leading city of SI This invention is a method of purifying water in the sister compound containing tannin polymer. The raw water of rivers, lakes or groundwater usually contains suspended solids. The buoyant matter must be purified to remove the water provided by M to be used in homes and industries. Suspended matter can be composed of large solids that can only be settled by gravity without using external force and non-settable materials (often colloidal). The removal of suspended material is usually done by coagulation, flocculation and sedimentation. The above three methods are called the conventional purification method (see Betz Handbook of Industrial Water Conditioning, 9th Edition, 1991, Betz Laboratories, Inc.,

Trevose, PA, pages 23 through 30). Naturally occurring suspended particles are mainly negatively charged. Water-soluble organic cationic polymers such as polyamines and polydiallyldimethylammonium chloride are commonly used to purify water with high turbidity (greater than 60 NTU, measured by the degree of turbidity). In low turbidity water (below 60 NTU), when the water is treated only with cationic polymers, there are usually not enough particles to form settleable flocs. Non-condensing coagulants such as aluminum sulfate, polymeric aluminum oxychloride, iron sulfate, osmium oxychloride, and sodium aluminate are used instead. These inorganic coagulants are quite cheap and are generally effective for purifying water. However, it tends to produce bulky sludge and is difficult to dehydrate. In addition, the inorganic coagulant is effective only in a specific pH range, so it is necessary to adjust the pH of the water during treatment. In addition, the residual iron and aluminum ions in the treated water will affect downstream operations such as cooling and hoe furnace treatment. When the water is finally discharged, it will also cause health and environmental problems. —4 — This paper scale is applicable to the Chinese National Standard (CNS) Μ specification (210X297mm) 83 · 3.10,000 I. · III Pack I j II ί order i—κ n ^ i (please read the notes on the back ^ (Fill in this page) 3 ^ 26qs A7 _- __ Printed by the Employees ’Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5.

The true color concentration is determined by measuring the absorption rate of the sample that has been filtered through the 0.45 microfilter at 455 μm. The absorbance is determined using a HachDR 2000 spectrophotometer that uses a calibration to convert the absorbance value to a standard platinum-cobalt color unit (Pt-Co cu). Aiming at the two-component treatment, the test sequence includes: adding the polymer containing tannin to the test substrate, mixing for 2 minutes, adding the anionic flocculant to the treated substrate, mixing for 20 minutes, shoveling and settling for 15 minutes and Measure the turbidity of the supernatant.

V. Description of the invention (23) Printed by the Employees ’Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs From the turbidity data, it can be seen that all Santuo experimental polymers can be improved with regard to the purification of oily wastewater. It is important to note that the polymer of Example 21 can reduce the turbidity to 2.2 ntu at a dose of 25 ng / Ι (Test # 14). This treatment can be compared with aluminum sulfate treatment at 125 mg / 1, which reduces the residual turbidity to 1.8 (Test # 5). A comparison of the theoretical amounts of sludge solids produced by these treatments shows that 125 mg / 1 aluminum sulfate will produce 65 mg / ιη solids due to the precipitation of aluminum hydroxide, while 25 mg / 1 of Example 21 will produce approximately 25 ms / Ι solid. This represents a reduction of 62¾ in waste sludge, a significant reduction that will result in substantial savings in the cost of sludge treatment in waste treatment plants. A sample of oily water from an aluminum processing plant was used for the suspension separation test. The clarity of water is determined by measuring the degree of oil and oil content. The turbidity of untreated wastewater is 71.6 ntu and the extractable oil content of fluorocarbon refrigerant is 252 ppm. Samples of the oily waste water were put into a 400 ml cup and treated with various doses of aluminum sulfate in Example 23. The following procedure is to design the mixing condition within the proposed full scale wastewater treatment system, which is used for the evaluation of the separation test of suspended objects ° 1) 200 ml / test; use a 1 ″ Χ2 " paddle to mix the sample at 400 m 丨In the beaker; 2) Add coagulant and mix § 125 rpm; mix for 36 minutes g 125 rpm; (KHaOH adjust pH to 7.0 to 7.5); 3) Add 4 mg / 1 polymer 1125L (AA / AM copolymer ) As Condensation-26- (Please read the precautions on the back before filling in this page) -The Chinese standard of the binding paper size (CNS & A4 specification (210X297mm) 83. 3.10,000 Central Standard of the Ministry of Economic Affairs Printed by Bureau Cooperative Consumer Co., Ltd.
