Embodiment 1

[0020] Embodiment 1, the processing method of domestic sewage treatment, sewage treatment agent A weight component is: 8 kilograms of furnace ash waste material, aluminum ash waste material 2 kilograms; Under normal temperature and pressure, by weight 1% A weight component and domestic sewage The ratio is 99% by weight, pour 10 kg of component A with 1% by weight into the mixing tank and stir evenly, and then slowly pour 990 kg of domestic sewage in the filter tank into the mixing tank with a weight of 99% , Stir evenly with component A of the sewage treatment agent for 1 minute or 2 minutes or 3 minutes or 4 minutes or 5 minutes, let it stand for 2 hours and then pour it into the sedimentation tank or purification tank to reach industrial water.

Embodiment 2

[0021] Embodiment 2, the processing method of controlling paper mill sewage is divided into two steps: under normal temperature and pressure, the first step is to control sewage agent B component calcium oxychloride powder waste 8 kilograms, aluminum potassium sulfate powder waste 2 kilograms; Pour 10 kg of 1% by weight into the sewage mixing tank and stir evenly, then slowly pour 990 kg of paper mill sewage in the filter tank into the sewage mixing tank with a weight of 99% by weight, and mix well with component B of sewage treatment agent At any time within 1 to 5 minutes, put it into the sedimentation tank after standing for 2 hours; the second step is: pour the sewage treatment agent A component into the sewage mixing tank: 8 kg of furnace ash waste, 2 kg of aluminum ash waste; Then stir evenly for 1 to 5 minutes at any time, and after standing for 2 hours, pour it into the sedimentation tank or purification tank to reach industrial water.

Abstract

The invention relates to a process and a special device for treating domestic sewage and waste water of a paper mill. At present, the emission of much waste water causes serious pollution to the environment, and the treatment method of the waste water has a biological treatment method, a physical treatment method, and the like. The biological treatment method has long treatment time and low speed; the physical treatment method has high treatment cost and halfway treatment, and can not achieve the emission standard. The invention aims at designing a process and a special device for treating domestic sewage and waste water of paper mill. Waste water treatment agent A comprises the following components according to the weight: 8 portions of furnace dust waste stock and 2 portions of aluminum dust waste stocks; waste water treatment agent B comprises the following components according to the weight: 8 portions of calcium oxide waste stock and 2 portions of aluminum potassium sulfate powder waste stock; and 1 percent of the A component and 99 percent of the domestic sewage are uniformly mixed in a mixing tank according to the weight and then are settled to obtain industrial waste. The invention treats the domestic sewage and the waste water of the paper mill by utilizing the waste water treatment agent, which has high speed and more thorough treatment, can achieve the emission standard, and can be repeatedly utilized, thereby saving water resource.

Description

1. Technical field [0001] The invention belongs to a method for treating sewage, and specifically refers to a process method and a special device for treating domestic sewage and paper mill sewage. 2. Background technology [0002] At present, many sewage discharges have caused serious pollution to the environment. Some sewage discharges not only pollute surface water, but also pollute underground water sources, affecting natural organisms, and even affecting human life and life safety. Sewage treatment methods include biological treatment methods and physical treatment methods. The biological method takes a long time to process and the speed is slow. For example, it takes 3 days to treat papermaking sewage in a paper mill, and the efficiency is low; the material method has high processing costs, and the treatment is not thorough and cannot meet the discharge standards. [0003] There are multiple channels for sewage treatment. For example, the State Intellectual Property O...
