The invention discloses a method for the advanced treatment of wastewater. The method comprises the following steps of: 1) filtering off-standard wastewater, delivering the wastewater into a catalytic ozonation tower, and simultaneously adding ozone for contact oxidization reaction; 2) delivering the effluent of the catalytic ozonation tower into an oxidization buffer stabilization basin for stabilization; 3) and after the stabilization, delivering the effluent into a BAF basin for treatment, and delivering discharged water into a clean water basin. The method reduces the addition amount of the ozone, improves the utilization efficiency of the ozone, converts the ozone into hydroxyl radicals by using a metal catalyst, and reduces the activation energy of hydroxyl radical oxidation reaction to promote hardly biodegradable macromolecule organic substances in the wastewater to be oxidized into easily biodegradable micromolecule substances, so that the biochemical limit to refining the wastewater is broken through and the biodegradability of the wastewater is increased; and the water quality of the effluent can meet the provincial standard of Jiangsu province, namely Chemical IndustryMain Water Pollutant Discharge Standard, completely by further treatment in the BAF basin.

The invention provides a water pipe cleaning agent, which comprises 12-50 parts by weight of natural organic acid, 10-50 parts by weight of citric acid, 10-15 parts by weight of natural surfactant, 10-15 parts by weight of part of natural fungicide and 10-25 parts by weight of water. The invention provides a cleaning agent for a water pipe, which can effectively remove the scale, rust and sludge and realize high-efficiency sterilization through physical and chemical reactions between the cleaning agent and the scale, rust and sludge on the inner wall of the water pipe. The water pipe cleaning agent of the present invention is all edible materials, has no secondary pollution to water pipes, and will not cause other harm to the human body even if there is residue; and the cleaning process is simple, the cleaning equipment is simple and easy to obtain, and the cost of the cleaning agent and the cleaning process is low. It has a high degree of acceptance, is suitable for large-scale promotion and application, and has broad development prospects.

The invention discloses a synergist for treating sewage containing high-concentration nonionic surfactants, a preparation method and application thereof. The synergist is prepared from the raw materials in the following weight percentages: C 1 ~C 5 Primary alkyl alcohol 1~10%, C 1 ~C 3 1-30% of aldehydes, 1-40% of pH regulators, 1-20% of amine polymers, and the balance is water. The synergist provided by the present invention is a high-molecular polymer, which contains a large amount of anchoring groups such as -OH, -NH, COO-, etc., and can quickly absorb the micelles formed by non-ionic surfactants in sewage, so that it can be simply and quickly Remove high-concentration non-ionic surfactants in sewage; in addition, after the synergist is used in conjunction with PAC and PAM, it can significantly reduce the sewage turbidity from 1200NTU to 12NTU, and the water quality after treatment is clear and transparent. The synergist uses The process is simple, convenient and fast, and is suitable for the treatment of a large amount of high-concentration non-ionic surfactant sewage, with a wide range of applications.

The invention relates to a kitchen waste treatment process. The kitchen waste treatment process comprises the following steps: (1) carrying out pretreatment for dividing the kitchen waste into a solid-phase material, an oil-phase material and a water-phase material through a pretreatment system; (2) carrying out primary filtering treatment for introducing the water-phase material into a first filtering system, wherein the first filtering system comprises a first filtering film component, the water-phase material is filtered by a cross flow filtration manner through the first filtering film component, the obtained filtrate is primary treatment water, and the trapped molecular weight of the first filtering film is 250000; and (3) carrying out secondary filtering treatment for introducing the primary treatment water into a second filtering system, wherein the second filtering system comprises a second filtering film component, the primary treatment water is filtered by a roll type filtering manner through the second filtering film component, the obtained filtrate is dischargeable water, and the trapped molecular weight of the second filtering film is 100. The treatment process is capable of effectively removing pollutants in the kitchen waste; the obtained water is clear and transparent and meets the discharge standard; in addition, the water production rate of the treatment process reaches over 85 percent.

The invention discloses a ship clearance oil dehydrating agent and a preparation method thereof and relates to clearance oil. The ship clearance oil dehydrating agent comprises the following components in percentage by mass: 25-60 percent of three-block-polyether, 1-5 percent of a demulsifying compound and 35-70 percent of a solvent. The three-block-polyether can be selected from imidazoline poly-oxypropylene polyoxyethylene polyoxypropylene ethers and polyethylene polyamine poly-oxypropylene polyoxyethylene polyoxypropylene ethers by mixing; the demulsifying compound can adopt NaCl aqueous solution; and methanol or ethanol can serve as the solvent. The preparation method comprises the following steps: heating and dissolving the three-block-polyether, uniformly mixing with the demulsifying compound and the solvent, thereby obtaining the ship clearance oil dehydrating agent. The amount of the ship clearance oil dehydrating agent is small and is about 100-250ppm. The dehydration effect is good, the dehydration rate can be over 99.5 percent, the oil-water interface is clear, and the water is clear and transparent. The dehydration speed is high, and the time from the operation of adding the ship clearance oil dehydrating agent to the operation of allowing an oil-water transition layer to completely disappear is only 15 minutes. The broad spectrum property is high, and the cost is low.
