Embodiment Construction

[0006] Composition standards and preparation methods of medicines:

[0007] 1. Drug No. 1: crush quicklime into powder, mix it with sodium hydroxide 1:1, and then dilute it with tap water at a ratio of 1:4 to form a liquid. The pH value is 14.

[0008] 2. Drug No. 2: After mixing half of the solid polyaluminum chloride and polysilicon chloride together, dilute it with tap water at a rate of 1:3. Then use 30% concentration of liquid hydrochloric acid and coal-fired boiler electrostatic precipitator dry dust in a ratio of 10:1 to prepare and soak, then add polyaluminum chloride and polysilicon chloride liquid to adjust the pH value within 2-3.

[0009] 3. Drug No. 3: Mix 1 / 3 of Japanese-made PAM with a molecular weight of 12 million to 16 million, domestic polyacrylamide with a molecular weight of 8 million, and polycyclic aromatic hydrocarbons with a molecular weight of 6 million, and dilute with 0.25mg‰ or 1mg‰ of tap water to prepare liquid.

[0010] 4. Drug No. 4: Dilute ...

Abstract

The invention discloses a preparation method and an application method for a medicament used for deslagging and clarification of domestic wastewater, relating to the domestic wastewater treatment clarification field. A plurality of chemical agents are mixed and diluted into liquid according to the proportion, and are dissolved into the domestic wastewater at different time in three stages to destroy chemical bonds in the domestic wastewater and change the characteristic of the domestic wastewater, so that impurities in the domestic wastewater such as suspended substances and so on, are completely separated from water and are precipitated and the water quality is clear and transparent; and COD, SS, ammonia nitrogen and a pH value in the water can reach the domestic wastewater pollution discharge standard stipulated by the environmental protection department and can be circularly reused to irrigate flowers, grass and trees, and wash cars and so on. The medicament and the method can not cause secondary pollution to a water body.

Description

technical field [0001] The invention relates to the field of treatment and purification of domestic wastewater. Background technique [0002] The discharge of domestic wastewater has brought greater pressure to environmental governance. Using the original anaerobic, aeration, amplitude flow, sedimentation or biological methods to treat domestic wastewater can no longer adapt to solve the current large-scale discharge of urban domestic wastewater. hazards to the environment. Contents of the invention [0003] The purpose of this invention is to solve the problem of separation and purification of pollutants and water in domestic wastewater in a short period of three minutes, so as to achieve the discharge of purified water up to standard or reuse for watering flowers, trees, car washing, etc., and use medicaments to make the separated waste residue It will not cause secondary pollution to the environment. [0004] The technical scheme of the present invention is: adopting ...
