Problems solved by technology

The traditional powdery flocculants are generally added by diluting with water, and they need to be added after stirring, aging and other processes. High, drug concentration and dosage are difficult to accurately control, resulting in difficult to achieve the expected treatment effect; at the same time generally rely heavily on commercial solid powder drugs, generally need to pre-store a large number of commercial drugs, high requirements for the storage of drugs , the stacking of a large amount of chemicals can easily lead to deterioration of the chemicals, affect the treatment effect, and cause a certain amount of waste
[0005] After the powder medicine has gone through a series of processes such as liquid preparation, powder making, transporta

Abstract

The invention relates to an electrolytic reaction tank and an integrated preparing and casting device for an iron and aluminum compound flocculant. The electrolytic reaction tank (18) comprises an aluminum electrolytic reaction area (3), a buffer area (6), an aerating area a (7), an aerating area b (14) and a compound electrolytic reaction area (9) communicated sequentially. A water inlet tube (5) is arranged at the bottom of the aluminum electrolytic reaction area (3), and the top of the aluminum electrolytic reaction area (3) is communicated with the buffer area (6) which is communicated with the bottom of the compound electrolytic reaction area (9) through a circulating pipe a (12), a circulating pump a (15), a circulating pump (10) and a circulating pipe b (13). The integrated preparing and casting device for the iron and aluminum compound flocculant comprises a flow control device (17), the electrolytic reaction tank (18) and a metering pump (19) communicated sequentially. The device is small in occupied area, and medicaments are not prepared for a long time.

Description

technical field [0001] The invention belongs to the field of water treatment, and specifically relates to an electrolytic reaction tank and an integrated device for preparing and adding an iron-aluminum composite flocculant, which is suitable for the treatment of domestic sewage, industrial waste water, surface water and underground water, and purification of drinking water. Wait for the process. Background technique [0002] Flocculant plays an important role in the process of water supply and wastewater treatment and sludge dehydration treatment. Generally, the treatment of municipal sewage and industrial wastewater requires the addition of flocculants to improve the quality of effluent water; the use of coagulants is more common in the process of drinking water and surface water treatment; Add flocculant to increase dehydration effect and improve filter cake properties. [0003] At present, the most widely used inorganic flocculants at home and abroad mainly include alu...
