Abstract
An attapulgite sewage handling method is to grind the attapulgite powder into attapulgite of 101 to 600 meshes and then pour the attapulgite into the awaiting sewage to stir. Then, 24 percent of octadecyl trimethyl ammonium chloride is poured into the sewage and stirred; then a flocculent is poured into the sewage and stirred and settled, and the water-soil separation, microorganism treatment and standard discharge are carried out. The weight ratio of the sewage and the attapulgite is 1000:0.1 to 1000:1.5; the dosage ratio of the attapulgite and the octadecyl trimethyl ammonium chloride is 4:1 to 4:3; the dosage ratio of the attapulgite and the flocculent is 1:1 to 4:1. The method can be used for treating hotel sewage, dyeing sewage, pesticide sewage and oilfield sewage and has the advantages of low treatment cost, saved time and labor, strong flocculation and easy raw material attainment.
Description
Technical field
The present invention relates to use attapulgite and tensio-active agent, flocculation agent acting in conjunction, absorption and cohesion combine the method for disposing of sewage.
Background technology
CN1275873 discloses China Petrochemical Industry Company's " a kind of wastewater purificant and its production and application " patented technology, utilize clay minerals such as organic attapulgite soil to make sorbent material, with siliceous flocculating aids and high-valency metal salt, drop into by a certain percentage and carry out purifying treatment in the sewage.It is natural that this patent is selected component A for use or positively charged ion attapulgite, the particularly latter need specific equipment, factory building to produce, the cost height, speed is slow, and this patent also needs B component, C component to be blended into scavenging agent, and it is various to form the product raw material type, give and collect raw material, account cost brings unfavorable.From molecular structure relatively, it is fibrous that attapulgite is, and has stronger flocculation function than the wilkinite of sheet structure, and molecular moisture capacity is low, dehydration easily, sludge volume is little.
Summary of the invention
The objective of the invention is above-mentioned deficiency at prior art, a kind of cationization attapulgite that does not need Special Equipment and factory building to produce is provided, fast and the cost-saving, the attapulgite sewage water treating method that the raw material of scavenging agent is formed is simple, the buying raw material is convenient, cost is low.
Above-mentioned purpose can realize by following measure: this attapulgite sewage water treating method is that attapulgite is ground into 101-600 purpose attapulgite, pour in the treatment sewage, stirred 5-20 minute, to be 24% octadecyl trimethyl ammonium chloride again as surfactant concentrations, pour in the pending sewage, stirred 5-20 minute fast, pour polyacrylamide again into as flocculation agent, the polymerization quaternary amine, at least a in the polymer-inorganic aluminium salt, stirred 5 minutes, sedimentation 2-20 minute, carry out mud again and separate, or microbiological treatment, the all follow-up works of qualified discharge; Sewage is 1000: 0.1～1000: 1.5 with the weight ratio that drops into attapulgite, and the consumption weight ratio of attapulgite consumption and octadecyl trimethyl ammonium chloride is 4: 1～4: 3, and the consumption weight ratio of attapulgite and flocculation agent is 1: 1～2: 1.
Said treatment sewage is hotel sewage, dyeing and printing sewage, pesticide sewage, oilfield sewage, and their main organic dirt is fermentation resolvent, microorganism and the residue thereof of ight soil, bath water dirt, kitchen and food and drink residuum, crude oil, oil field chemical, pigment dyestuff and solvent, organophosphorus, heterogeneous ring compound and intermediate, tensio-active agent.
The invention has the beneficial effects as follows: do not need earlier attapulgite to be carried out special disposal, province's equipment, cost-saving, save time, economize the labour, the raw material type that purifies usefulness is few, purchase conveniently, and the cost of sewage disposal is low, and flocculation ability is strong.
Embodiment
The present invention is described in further detail below in conjunction with embodiment: following table is sewage purification per ton required attapulgite, tensio-active agent, flocculation agent raw material and a kilogram number proportioning table when handling.
Now be that example is set forth its treatment process: calculate the sewage total amount with the sewage lagoon volume earlier with the hotel sewage, the raw material of embodiment 1 hotel sewage and kilogram number proportioning in the synopsis again: drop into attapulgite 0.3kg with sewage per ton and stirred 15 minutes, drop into concentration again and be 24% octadecyl trimethyl ammonium chloride 0.1kg, stirred 30 minutes, drop into concentration again and be 1% polyacrylamide 0.3kg and polymerization season win salt 0.1kg, stirred 15 minutes, sedimentation 30 minutes, supernatant liquid is extracted out with water pump, lower floor's sediment dewaters with whizzer or plate-and-frame filter press, further purify as need, also available microbially decontaminate is handled, but mud brickmaking, make fertile mud.
The oilfield sewage of all the other embodiment 2 can be handled by the same method of the hotel sewage of previous embodiment 1 according to raw material corresponding in the table and kilogram number.
It should be noted that the quantity that each the raw material input amount in the table is just calculated with sewage per ton, the input amount of the whole various raw materials of pond sewage should multiply by amassing of each raw material kilogram number with the tonnage of sewage gross weight and calculate.Because of the Organic pollutants degree difference in different hotels, oil field is very big, the injected volume of each raw material and the ratio of treatment sewage, it is more wide in range than the ratio of four embodiment to be bound to, when actually operating, can break through fixed interval value.What therefore embodiment was listed is ratio commonly used, and other embodiment that is in end value gives an example no longer one by one because of understanding.
The raw material that the present invention is used such as the concentration of polyacrylamide are 1%, the concentration of octadecyl trimethyl ammonium chloride is 24%, injected volume among the embodiment is meant the amount that should drop under this concentration content condition in the sewage, as the concentration value difference, calculate corresponding injected volume again, this belongs to simple the conversion, does not give unnecessary details.Available polymerize aluminum chloride, polyaluminium sulfate are used the technical pure level in solid matter in the flocculation agent such as the polymer-inorganic aluminium salt.
Now manage effect with the several typical index in the open: hotel sewage chemical oxygen demand (COD) is less than 70mg/L, and fat content is less than 15mg/L, the COD＜100mg/L of oilfield sewage, fat content＜100mg/L.The dyeing sewage decoloration rate reaches 92%, and the chemical oxygen demand of insecticide factory's sewage (COD) is less than 90mg/L.
