Abstract
The utility model discloses a purifier of sodium sulphate waste water has three first order reaction groove, second order reaction groove and third -stage reaction groove of establishing ties in proper order through the pipeline, all be equipped with a centrifugal pump on the pipeline that first order reaction groove and second order reaction groove, second order reaction groove and third -stage reaction groove are connected, 3 the interior agitator and the level gauge of all being equipped with of individual reaction, the upper end in first order reaction groove are equipped with that sodium sulphate waste water entry, calcium hydrate emulsion drop into mouthful and calcium bisulfite drops into mouthful, and all be equipped with the calcium hydrate emulsion on second order reaction groove and the third -stage reaction groove and drop into the mouth, the bottom in third -stage reaction groove is equipped with the pressure filter, the utility model discloses simple structure, low in production cost, sodium sulphate content in the tail washings is low, and the long service life of equipment can be applied to the sodium sulphate waste water that trades such as purification treatment desulfurization, chemical industry and environmental protection produced widely.
Description
Technical field
This utility model relates to chemical wastewater treatment technical field, the purifier of a kind of sodium sulfate wastewater.
Background technology
Can produce substantial amounts of sodium sulfate wastewater in the industries such as desulfurization, chemical industry metallurgical and environmental protection, the waste water of sulfur acid sodium can cause serious pollution after entering water body, causes water acidification, and pH reduces, and endangers aquatile；Meanwhile, the sulfate reducting bacteria in water body under anaerobic can make SO4 2-Convert and produce toxic gas H2The higher sulfur of S even toxicity, for sulfide etc., is directly detrimental to health and water ecology balances；Enter farmland and can destroy Soil structure, make soil compaction, reduce the yield of crops and reduce quality of agricultural product；As the concentration up to 1000mg/L of sodium sulfate in drinking water, sodium sulfate inhibits the secretion of gastric juice, and the lowering of concentration of gastric juice causes peptic activity of stomach to decline, and hinders digestion.
At present, domestic process sodium sulfate wastewater mainly has three kinds of methods: (1) sulfur acid sodium waste water produces the sodium hydroxide of low concentration, but owing to the method energy consumption is high, poor product quality, during produce stink damp body pollution environment, and the sodium sulfate of only about 30% changes into sodium hydroxide；(2) sulfur acid sodium waste water produces chlorideless potassic fertilizer (potassium sulfate), and due to the heavy corrosion to equipment of the chloride ion in solution under the high temperature conditions, the service life causing equipment is short, and production cost is high；(3) crystallization of sulfur acid sodium waste water produces sal glauberi, can not contact with container owing to during atmospheric evaporation, heat source temperature is too high, and big to requirement height, the energy consumption of equipment when being evaporated under reduced pressure, thus increases cost.Therefore three of the above method all can not be used widely, therefore, research and develop a kind of low cost, the purifier of length in service life is important topic of the present utility model.
Summary of the invention
The problems such as it is high that the purpose of this utility model is aiming at current sodium sulfate wastewater purifier cost, pollution environment in processing procedure, high to equipment requirements, service life is short, it is provided that a kind of easy and simple to handle, the purifier of the sodium sulfate wastewater of low cost.
The technical solution of the utility model is: the purifier of a kind of sodium sulfate wastewater, be there are three first order reaction grooves being sequentially connected in series by pipeline, secondary response groove and third-order reaction groove, described first order reaction groove and secondary response groove, a centrifugal pump it is equipped with third-order reaction groove on the pipeline that secondary response groove is connected, it is equipped with agitator and liquidometer in described 3 reactive tanks, the upper end of first order reaction groove is provided with sodium sulfate wastewater entrance, calcium hydroxide emulsion input port and calcium bisulfite input port, it is equipped with calcium hydroxide emulsion input port on secondary response groove and third-order reaction groove, the bottom of described third-order reaction groove is provided with pressure filter.
The top of first order reaction groove described in the utility model, secondary response groove and third-order reaction groove is cylindrical, and bottom is inverted cone.
Agitator described in the utility model goes directly reaction tank bottom.
Sodium sulfate wastewater entrance described in the utility model, calcium hydroxide emulsion input port and calcium bisulfite porch are equipped with flow transducer.
This utility model simple in construction, design ingenious, once add calcium bisulfite by the reactive tank of three series connection and three addition calcium hydroxide emulsions carry out three times to the sodium sulfate in waste water and process, thus the conversion ratio of the sodium sulfate in waste water is high, sodium sulfate residual quantity in tail washings is only about 20%, the most traditional method；Owing to the sodium sulphate content in tail washings is low, thus avoid the sodium sulfate produced containing water of crystallization, block production system, cause production system to be collapsed in 7 days to one month, and use this device can run half a year more than, greatly reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 first order reaction groove, 2 secondary response grooves, 3 third-order reaction grooves, 4 pipelines, 5 centrifugal pumps, 6 liquidometers, 7 agitators, 8 pressure filter, 9 flow transducers.
