Embodiment 1

[0052] Taking the groundwater somewhere in Xi'an City, Shaanxi Province as an example, the total hardness of the reactor effluent was monitored in the laboratory; the total volume of the dynamic simulation test device was 6.3L, the height of the catchment area C was 3cm, and the radius was 10cm; The volume is 1.26L, the zone height is 5cm, and the zone radius is 10cm; the volume of the aeration stripping zone B is 5.03L, the zone height is 16cm, and the zone radius is 10cm;

[0053] The initial temporary hardness of the water to be treated is 35.92mg·L -1 , the amount of hydrochloric acid added is 800ul / L (the numerical value after calculation is taken as the hundredth integer of the amount of acid added and added), the flow rate of water treatment is 133.1ml / min, and the concentration of hydrochloric acid is 1mol / L.

[0054] See the contrast chart after boiling before and after treatment Figure 5 . After several hours of continuous operation, the results show that the pH o...

Abstract

The invention discloses integrated water scale removal equipment, and solves the problem that a scaling phenomenon is generated caused by the fact that a precipitate is formed after water with high temporary hardness is boiled. The integrated water scale removal equipment comprises a water-collecting area, an aeration stripping area and an acid adjusting area from top to bottom; water to be treated and acid are subjected to hybrid reaction in the acid adjusting area to generate CO2 gas, water containing CO2 gas flows to the aeration stripping area, through an aeration stripping action, CO2 gas in water can escape into air, and through the water-collecting area, water in CO2 gas is collected and removed. The equipment is simple in integral structure, all functional units are compactly connected, the flat space utilization rate is high, the principle is simple, the operation is convenient, and the water scale removal rate to raw water with large temporary hardness is relatively high.

Description

technical field [0001] The invention relates to equipment in the technical field of water supply, in particular to an integrated scale removal equipment. technical background [0002] Groundwater is an important and high-quality drinking water source for Chinese residents. Large and medium-sized cities generally use surface water sources due to their large water consumption. Surface water sources mainly include rivers, lakes, reservoirs, etc., which are characterized by low hardness, but there are many suspended impurities, organic matter and bacteria, water treatment is relatively complicated, and it is easily affected by the external environment impact and pollution, and use groundwater as a backup water source for the city. Compared with surface water, groundwater has less suspended impurities, less organic matter and bacteria, relatively easy water treatment, and is not easily affected and polluted by the external environment. Groundwater is widely used in small and med...
