Abstract

The invention relates to the technical field of hard water treatment and utilization systems, in particular to a tap water hardness softening and wastewater recycling system. According to the technical scheme, the system comprises a hard water treatment assembly and a waste water utilization assembly, the hard water treatment assembly comprises an activated carbon filter, the output end of the activated carbon filter is connected with a full-automatic water softener, the output end of the full-automatic water softener is provided with a softened water tank, the output end of the softened water tank is provided with a washing tower, the output end of the washing tower is connected with a wastewater storage tank, the output end of the wastewater storage tank is connected with an air floatation tank, and the output end of the air floatation tank is connected with a wastewater relay tank. The system is used for softening hard water, improving the water treatment effect, reducing the water scaling probability, reducing the energy consumption, prolonging the service life of equipment, reducing the cleaning and maintenance cost, filtering wastewater for use, improving the energy utilization rate, avoiding scaling of a cooling unit, improving the workshop production efficiency and reducing the enterprise cost, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of hard water treatment and utilization systems, in particular to a tap water hardness softening and waste water reuse system. Background technique [0002] In factory workshop water, tap water is generally used after softening treatment. Since the production water of most local factories is rocky tap water, the water hardness is relatively high, with a total hardness (CaCO3) of 201mg / L, and serious scaling. Water scaling is due to the high hardness of water, that is, the high content of calcium ions in the water. After heating, it combines with carbon dioxide in the air to form calcium carbonate that adheres to the inner wall of the container. Contains a large amount of salts formed by calcium (Ca+) and magnesium (Mg+) ions. If it is directly used as water supply, it is easy to form scale on the heating surface of the equipment, which will reduce the efficiency of the equipment, increase the loss, reduce t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems existing in the background technology: the treatment of hard water is not perfect, a large amount of dirt is generated during use, causing equipment blockage, affecting the working efficiency of cooling towers, bringing economic losses, energy consumption losses, frequent maintenance and replacement of equipment, and increasing The proportion of consumables in large workshops increases production costs, and maintenance and repair affect the normal production of the frame. A system for softening tap water hardness and reusing waste water is proposed.
