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 an integrated scale removal equipment, which solves the problems of precipitation and scale formation after boiling water with high hardness temporarily. The integrated scale removal equipment includes a water collection area, an exposure Gas stripping area and acid adjustment reaction area, the water to be treated and acid are mixed and reacted in the acid adjustment reaction area to generate CO2 gas, and the water flow containing CO2 gas reaches the aeration stripping area, and the water is released by the aeration stripping effect The CO2 gas escapes into the air, and the CO2-depleted water is collected through the catchment area. The overall structure of the equipment is simple, the connection of each functional unit is compact, the plane space utilization rate is high, the principle is simple, the operation is convenient, and it has a high scale removal rate for raw water with high temporary hardness.
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...
