Abstract
A method of treating rubber product industrial waste water is disclosed. The method includes (1) adding a flocculating agent and a coagulant aid to pretreated waste water to flocculate and settle most low-molecular-weight polymers and suspending compounds in the waste water, (2) pumping the waste water and air into an air dissolving tank, reducing the pressure suddenly to allow insoluble suspending particles to be adhered to air bubbles and float along with the air bubbles so that the rest suspending compounds can be removed, (3) feeding the waste water treated in the step (2) to an aeration tank containing a microbe membrane, adding agar slurry, glucose, amino acids and composite vitamins, and aerating, and (4) feeding the waste water treated in the step (3) into a Fenton reactor, and thoroughly oxidizing and decomposing organic matters in the waste water. The method is simple and continuous in process, free of secondary pollution, high in waste water treatment efficiency, economical and practical.
Description
Technical field

Exhibition and the quickening of urbanization process, more show critical importance and the urgency solving water shortage problem.
Substantial amounts of water is needed due to producing in rubber industry, wherein in rubber industry in addition to latex product, its
His production waste water mostlys come from the process cycles cooling waters such as mixing, extrusion, calendering and extrusion, sulfuration waste water, produced
The waste water that the systems such as the lubrication in journey, cooling, transmission produce, contains organic particle in small, broken bits in waste water, some of them are organic
Composition granule difficult degradation, poisonous, so must process in time.
The organic matter containing in rubber industrial wastewater can affect the degree of purity of water, absorption harmful substance and bacterium, and
And good oxygen organic can reduce oxygen content of water, aquatic animals and plants death is made to cause water body stench, anaerobe amount reproduction
Putrefactive fermentation can occur simultaneously, make bacterial growth, deteriorate water quality, destroy water body.So work out a kind of energy effective process containing
The method of the waste water of large amount of organic is designated as important.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of processing method of rubber industrial wastewater.
A kind of processing method of rubber industrial wastewater, described processing method comprises the following steps：
(1) amount pressing 50g/L in the waste water of pretreatment adds flocculating agent and flocculation aid in waste water, contains due in waste water
There are many dispersion organic matters in small, broken bits, majority is the low polymer without cohesion, in the presence of flocculating agent and flocculation aid
Bulky grain sedimentation can be condensed into and then pass through Static Spinning polysulfones nanofiber pre-filtering membrane filtration；
(2) using pump and air compressor, the useless water and air that step (1) was processed is pressed in a dissolving, wherein
It is 5MPa that air is compressed to pressure through air compressor, makes air be dissolved in waste water and reach saturation, then by dissolved with air
Waste water sends into sudden pressure reduction after holding gas flotation cell, to atmospheric pressure, makes solubility in water for the air reduce rapidly, due to solubility
Reduce air to discharge from waste water in atomic little bubble, insoluble suspended particulate can stick on bubble with bubble
Floating, then removing step (1) does not have the suspension removing；
(3) waste water processing step (2) is passed into Air Exposure in the aeration tank containing microbial film, adds agar
Slurry, glucose, amino acid, B B-complex provide the energy needed for growth of microorganism, contained microbes on microbial film
Preliminary oxidation Decomposition is carried out to the organic matter in waste water, wherein constantly to aeration tank be passed through compressed air Air Exposure 12～
24h；
(4) waste water processing step (3) is passed in Fenton reactor, the organic matter processing through step (3) and useless
In water there is oxidation Decomposition in difficult decomposition, poisonous organic matter in Fenton reactor completely.
Further, described flocculating agent is aluminum chlorate of polymerized silicic acid (PACS) and FeCl3Powder in mass ratio 1:2 mixing
Mixture, described flocculation aid is polyacrylamide, active SiO2, bentonite, sodium carboxymethylcellulose press 2:3:3:4
The mixture that mixes of mass ratio.
Further, described aluminum chlorate of polymerized silicic acid (PACS) is made of with aluminium chloride, the concentrated sulfuric acid, sodium metasilicate as raw material
's；Specifically preparation process is：Then plus matter a certain amount of sodium silicate solids powder is taken to be configured to the solution that mass concentration is 1%,
Measuring the dilute sulfuric acid acidifying that concentration is 10% and adjusting PH is 1.5～2, then stands 2min, then again by solid-to-liquid ratio 3:2 addition chlorinations
Aluminium stirs 5～10min in the homogenizer of 4500～5000r/min and makes.
Further, described Air Exposure is mainly organic matter in reinforcement pond and is contacted with microorganism and dissolved oxygen, thus
Ensureing that in pond, microorganism is under conditions of having sufficient dissolved oxygen, oxidation Decomposition being carried out to organic matter most of in sewage, thus subtracting
The content of useless Organic substance in water less.
Further, added in described aeration tank agar slurry, glucose, amino acid, B B-complex are by weight
Ratio 5:3:2:Added by 1, the amount of addition is the 0.2% of waste water gross mass.
Further, described waste water is added thereto to as added cohesion in step (1) after Fenton reactor process
Agent and flocculation aid stand 20～30min, then directly discharge described waste water after glass fibre milipore filter ultrafiltration.
Beneficial effects of the present invention are embodied in：The present invention combines Air Exposure and Fenton's reaction processes rubber Industry Waste
Water, the organic matter in the thorough Decomposition Wastewater of energy, and also handling process is simply continuous, will not produce secondary pollution in processing procedure,
Economical and practical.
