Problems solved by technology

[0003] Since the water temperature has a significant impact on the coagulation effect, in order to improve the coagulation effect of low-temperature water, the current common method is to increase the dosage of coagulant and add polymer coagulant, so that the coagulant and coagulant are used together to Improve the density and strength of flocs, but it is difficult to obtain a good coagulation effect even if a large amount of coagulant is added, which not only causes waste of coagulant, but also increases project investment and operation costs

Description

technical field [0001] The invention relates to the technical field of feed water treatment, in particular to a low-temperature feed water flocculation device of solar heat and power cogeneration type. Background technique [0002] The flocculation device is used to coagulate the sewage to achieve the effect of sewage purification. In the cold climate area of ​​our country, the surface water temperature is sometimes as low as 0-2°C in winter. Affected by the low temperature, the formation of flocs is slow, and the floc particles are small and loose, which cannot achieve the expected goal. The main reasons are as follows: (1) The hydrolysis of inorganic salt coagulant is an endothermic reaction, and the hydrolysis of low-temperature water coagulant is difficult; (2) The viscosity of low-temperature water is high, which weakens the Brownian motion intensity of impurity particles in the water and causes collisions. The opportunity is reduced, which is not conducive to the dest...
