Embodiment Construction
[0027] Refer to the accompanying drawings in the manual figure 1 , figure 2 , a wastewater softening processor, which is divided into a coagulation reaction zone I and a precipitation separation zone II. The upper part of the coagulation reaction zone I is provided with a baffle tank 13, a stirring 8, a waste water inlet pipe 1, a chemical addition pipe, and a radial baffle Plate 11, baffle groove downcomer 14. Sedimentation and separation zone II is provided with a waste water outlet pipe 2, a sludge discharge pipe 3, a waste water return pipe 9, and an anti-scaling pipe 15. A waste water distributor 16 is arranged below the waste water downcomer 12 . The medicament adding tube has medicament a adding tube 4, medicament b adding tube 5, medicament c adding tube 6 and flocculant adding tube 7.
[0028] The baffle tank 13 is divided into three sections in sequence according to the direction of waste water flow. The first section III is provided with a waste water inlet pipe...

The invention provides a waste water softening processor. The waste water softening processor comprises a coagulation reaction zone and a deposition separation zone which are arranged in a same container from top to bottom successively and are communicated by a waste water downcomer; and also comprises a medicine introduction pipe and a waste water inlet pipe which are arranged on the top end of the container, a waste water outlet pipe and a sludge discharge pipe which are arranged on the bottom of the container; a baffling groove and a stirring device are arranged on the upper part of the coagulation reaction zone; a flocculating agent adding pipe is arranged at the middle part of the coagulation reaction zone; a waste water downcomer is arranged at the lower part of the coagulation reaction zone; the deposition separation zone is arranged below the coagulation reaction zone, and comprises a waste water outlet pipe arranged on the top, a waste water backflow pipe arranged at the middle part, and a sludge discharge pipe arranged at the bottom of the deposition separation zone. The waste water softening processor is capable of solving problems in waste water softening processing that flocculation deposition time is too long, and equipment cost is high, and is especially suitable for recycling of coal chemical industry production waste water.
Description
technical field [0001] The invention belongs to the field of waste water treatment, in particular to a waste water softening processor. Background technique [0002] For a long time, the pollution control of high-salinity wastewater has not received enough attention. With the rapid development of chemical industry, metallurgy, electric power and other industries and urban construction, in order to save water resources, industrial wastewater and urban wastewater mostly use reverse osmosis technology. After treatment and reuse, the resulting various reverse osmosis concentrated water and high-salt wastewater such as industrial circulating water drainage have caused more and more serious environmental pollution problems. [0003] Reverse osmosis and evaporative crystallization are mainly used for these wastewaters with high salt content. Regardless of reverse osmosis or evaporative crystallization, a large amount of scaling components such as calcium, magnesium ions, and silic...
