Description

The process for purifying water of physics and chemistry water purifier at a kind of pickling waste waters
Technical field
The present invention relates to a kind of Water-quality treater process for purifying water, and in particular to physics and chemistry water purifier at a kind of pickling waste waters Process for purifying water, belongs to environment-friendly products technical field.
Background technology
Continuous progressive and scientific and technical with society continues to develop, and people become more concerned with the ground that we depend on for existence Ball, in the world most countries be also fully recognized that importance of the environment to our human developments.Pickling waste waters main source In plating, the pretreatment workshop section of metallurgical processing part, it is mainly characterized by that water is small, and pH is low, containing iron ion, petroleum-type, outstanding Float etc., pickling waste waters harm shows：Corrosion metal structure, concrete structure material；Suppress the growth of plant and microorganism, The influence ecological balance;The absorption dissolved in animals and plants nutrient of oxygen in influence water body；Alluvial, the muddiness of sewage are easily caused, if not Directly being discharged through treatment can have a strong impact on surrounding environment.Therefore, in order to solve problem above, it would be highly desirable to research and develop a kind of new pickling The process for purifying water of wastewater treatment water purifier.
The content of the invention
（One）The technical problem to be solved
To solve the above problems, the present invention proposes a kind of process for purifying water of physics and chemistry water purifier at pickling waste waters, and floor space is small, High treating effect, operating cost is low, can be widely applied to pickling waste waters treatment.
（Two）Technical scheme
The process for purifying water of physics and chemistry water purifier, comprises the following steps at pickling waste waters of the invention：
The first step：Pickling waste waters flows into regulating reservoir after removing larger granule foreign through grid；
Second step：Lifted to water purifier is changed, while being added by chemicals dosing plant with pump by after regulating reservoir equilibrium water quality and quantity NaOH solution；
3rd step：Waste water is neutralized in water purifier, aoxidized, coagulating sedimentation, qualified discharge after filtering；
4th step：The sludge of water purifier defends department's treatment by being pumped into sludge dewatering equipment press filtration, mud cake cross ring, and filtrate returns to tune Section pond is processed again.
Further, the specific method of the 3rd step is as follows：
a：Neutralization reaction, using dosing before pump, medicament is tangentially transported to whirl cylinder with waste water by elevator pump, using vortex Principle makes being sufficiently mixed for waste water and medicament, and neutralization reaction occurs, and the dosage of NaOH carries out On-line Control by pH meter；
b：Oxidation reaction, by air blower aeration aerating, controls pH>8, the ferrous iron in waste water is quickly converted to Fe (OH)3, mix Retrogradation is formed sediment；Fe(OH)3Solubility it is minimum, have very strong adsorption capacity to other colloidal solids in water, flocculation, settling property are good, Using the surface area of the settling area much larger than the conventional precipitation with size of tube settling, settling efficiency is increased substantially；
c：Coagulating sedimentation and filtering, sieving effect, settlement action and the adsorption-condensation for retaining pollutant by granular media are made With the suspended impurity in further removal waste water, to ensure that standard water discharge is discharged.
（Three）Beneficial effect
Compared with prior art, at pickling waste waters of the invention physics and chemistry water purifier process for purifying water, pickling waste waters through grid remove Regulating reservoir is flowed into after larger granule foreign, by being lifted to water purifier is changed, while logical with pump after regulating reservoir equilibrium water quality and quantity Cross chemicals dosing plant and add NaOH solution, waste water is neutralized in water purifier, aoxidized, coagulating sedimentation, qualified discharge after filtering, only The sludge of hydrophone defends department's treatment by being pumped into sludge dewatering equipment press filtration, mud cake cross ring, and filtrate returns to regulating reservoir and processes again, Floor space is small, and high treating effect, operating cost is low, can be widely applied to pickling waste waters treatment.
Specific embodiment
The process for purifying water of physics and chemistry water purifier, comprises the following steps at a kind of pickling waste waters：
The first step：Pickling waste waters flows into regulating reservoir after removing larger granule foreign through grid；
Second step：Lifted to water purifier is changed, while being added by chemicals dosing plant with pump by after regulating reservoir equilibrium water quality and quantity NaOH solution；
3rd step：Waste water is neutralized in water purifier, aoxidized, coagulating sedimentation, qualified discharge after filtering；
4th step：The sludge of water purifier defends department's treatment by being pumped into sludge dewatering equipment press filtration, mud cake cross ring, and filtrate returns to tune Section pond is processed again.
The specific method of the 3rd step is as follows：
a：Neutralization reaction, using dosing before pump, medicament is tangentially transported to whirl cylinder with waste water by elevator pump, using vortex Principle makes being sufficiently mixed for waste water and medicament, and neutralization reaction occurs, and the dosage of NaOH carries out On-line Control by pH meter；
b：Oxidation reaction, by air blower aeration aerating, controls pH>8, the ferrous iron in waste water is quickly converted to Fe (OH)3, mix Retrogradation is formed sediment；Fe(OH)3Solubility it is minimum, have very strong adsorption capacity to other colloidal solids in water, flocculation, settling property are good, Using the surface area of the settling area much larger than the conventional precipitation with size of tube settling, settling efficiency is increased substantially；
