Description

From preparation method and the preparation facilities of defeated and dispersed type long-acting slow-release purification of water quality filler brick
Technical field
The present invention relates to a kind of preparation method and preparation facilities from defeated and dispersed type long-acting slow-release purification of water quality filler brick, belong to environment-friendly materials technical field.
Background technology
Along with the further raising of the industrialized develop rapidly of China and intensive agriculture degree, the trade effluent producing, rural sewage and sanitary sewage have caused serious destruction to water environment. A large amount of unprocessed or process incomplete sewage and directly enter in the water body such as river, lake, cause comprehensive deterioration of rivers and lakes water quality. Meanwhile, in rural area, the excessive uses of agriculture input such as chemical fertilizer, agricultural chemicals, the unreasonable disposal of agricultural wastes such as feces of livestock and poultry, agricultural crop straw and farmland incomplete film, cause widespread pollution from the overuse of fertilizers and pesticides in rural area day by day serious, have aggravated soil and water pollution risk. China Large Or Medium Type Irrigation Areas is due to extensive farming mode, and applying quantity of chemical fertilizer is high, and livestock and poultry cultivation is intensive, and widespread pollution from the overuse of fertilizers and pesticides in rural area is even more serious, and in escape canal, nitrogen phosphorus and pesticide concentration are higher, after outer row, affects River water quality. In city, what the industrial wastewater of a large amount of discharges and sanitary sewage were serious affects river water environmental also and then the health of harm humans, along with the continuous propelling of modernization construction process, building the harmonious water environment of people's water becomes an Important Action that strengthens Urban Competitiveness, promotes city taste, sustainable economic development. Environmental pollution improvement also becomes modern society and faces one of major issue with urgently to be resolved hurrily.
The riverway water quality purification method using at city and country at present has more multiple, wherein building artificial swamp and ecological revetment is to use wider technology, utilize sewage after contacting with plant medium biomembrane, the maintenance of plant self function, the resource of fully purifying waste water, has the function of sewage disposal and landscape concurrently. But because this class biological purification method engineering construction cycle is long, investment is large, and onset is slow, for seriously polluted, burst Pollution thing exceeds standard, local should acute water environment treatment etc. occasion be not suitable for adopting said method. The traditional chemical reagent directly method of throwing in can reduce the water pollutant content in a certain region fast, be widely used in sewage treatment area, but because drug effect has just discharged in several hours, process range is limited, particularly for continuing moving water condition in river course, the medicine of throwing in cannot continue to play a role owing to discharging too fast, has brought difficulty to the environmental improvement of this class occasion. Therefore be badly in need of at present one can fast reducing water body in pollutant levels, can within one period, keep again the spacetabs type water quality purification material of stable purification efficiency, to expanding water environment treatment method, improve water environment processing horizontal and there is positive meaning simultaneously.
Summary of the invention
The present invention proposes a kind of preparation method and preparation facilities from defeated and dispersed type long-acting slow-release purification of water quality filler brick, prepared filler brick can be slowly defeated and dispersed in water, the water quality treating chemicals of doping in brick is evenly slowly discharged in water body, thereby reach the effect of water body being carried out to long-acting stable purification. The advantages such as the present invention has that medicament rate of release is stable, long action time, production cost are low, are applicable to various water conditions, can carry out large-scale production.
Technical solution of the present invention: from the preparation facilities of defeated and dispersed type long-acting slow-release purification of water quality filler brick, its structure comprises blanking mold and shake table; Wherein blanking mold comprises external mold, plug and mold base, the hollow circular-tube that described external mold is both ends open, and 5 plug at right angle settings, on mold base, offer stopper slot on mold base, and external mold is connected with mold base by stopper slot; Described shake table involving vibrations plate, support spring, vibrating motor and shake table support, wherein vibrating motor is installed on oscillating plate below, and oscillating plate is connected with shake table support by some support springs.
From the preparation method of defeated and dispersed type long-acting slow-release purification of water quality filler brick, comprise the following steps:
(1) stalk that is 1cm ~ 3cm by strain footpath carries out nature or artificial processed, after removal lateral lobe, puts into pulverizer, is ground into the particle that length is 1 ~ 1.5cm;
(2) stalk particle crushing is put into the water glass solution that modulus is 3.0, Baume degrees is 50.0 and soaked 30 minutes, take out natural drying 24 hours;
(3) choose applicable solid state chemistry reagent treatment, drying for standby according to the kind of pollutant in staying water;
(4) by stalk particle, sawdust, cement, flyash, river sand, carboxymethyl cellulose, NaHCO3, citric acid, chemical treatment reagent drop in mixer and be dry mixed 5 minutes according to the mass ratio of 50:20:80:50:100:1:3:1:5;
(5) dry mash stirring, water, vegetalitas blowing agent are dropped into the processing of foaming in cement foam maker according to: the mass ratio of 80:120:15, then pour in blanking mold, elemental height is mold height 3/4;
(6) mould is positioned on shake table and vibrates 5 ~ 10 seconds, after filling evenly in mould, leave standstill 30 minutes until slurry;
The present invention has following beneficial effect:
1) prepared filler brick has porous, expanded structure, structural strength is low, the sawdust comprising and stalk particle can be removed by dilation and erosion in water, impel matrix material to occur slowly defeated and dispersed, thereby the water treatment reagent adulterating in material is discharged slowly in water, improve the effective acting time to water body of filler brick, not only rapid-action to reducing water pollution substrate concentration, and can keep before the deadline stable purification efficiency;
2) the sawdust water-swellable adulterating in material and be corroded after can make filler brick surface occur successively to come off, stalk particle soaks after dilation and erosion is removed and can make material be bulk to peel off in water, by adjusting the additional proportion of sawdust and stalk particle, the defeated and dispersed speed in water of capable of regulating filler brick and complete defeated and dispersed time;
3) mixed slurry that comprises cement blowing agent carries out mechanical foaming in foaming machine, simultaneously NaHCO3Also can in slurry, generate a large amount of CO with citric acid reactions2Bubble, this physics and chemistry is combined foaming processing method can improve the porosity in filler brick effectively, has significantly reduced the structural strength of material, and has alleviated the weight of filler brick;
4) the present invention adopts stalk, flyash, river sand etc. as matrix trunk material, can not form secondary pollution after defeated and dispersed, simultaneously also for recycling of waste resource provides a kind of new approach;
5) by adjusting kind and the doping of chemical treatment reagent in filling block, the present invention can use under different water pollution conditions, has stronger adaptability;
6) the present invention is cylindrical loose structure, has larger solid liquid interface, is conducive to improve medicament response area, is conducive to the serial connection of filler brick and the stability laying simultaneously, is suitable for various water body environments;
7) the present invention is simple in structure, with low cost, rapid-action, is suitable for the short-term Emergency management of all kinds of polluted water bodies.
