Problems solved by technology

However, due to the long construction period, large investment and slow effect of this kind of biological purification method, the above method is not suitable for occasions such as serious pollution, sudden pollutants exceeding the standard, and local emergency water environment treatment.
The traditional method of direct injection of chemical reagents can quickly reduce the content of water pollutants in a certain area, and is widely used in the field of sewage treatment. However, because the drug effect is released within a few hours, the treatment range is limited, especially for rivers. Under continuous water conditions, the administered drugs cannot continue to play a role because they are released too quickly, which brings difficulties to the environmental governance of such occasions

preparation example Construction

[0035] Its preparation method: comprises the following process steps:

[0036] (1) Naturally or artificially dehydrate the straw with a plant diameter of 1cm~3cm, remove the side leaves, put it into a grinder, and crush it into particles with a length of 1~1.5cm;

[0037] (2) Soak the crushed straw particles in a water glass solution with a modulus of 3.0 and a Baume degree of 50.0 for 30 minutes, then take it out and dry it naturally for 24 hours;

[0038] (3) Select a suitable solid chemical treatment reagent according to the type of pollutants in the water body to be treated, and dry it for later use;

[0039] (4) Straw particles, sawdust, cement, fly ash, river sand, carboxymethyl cellulose, NaHCO 3 , citric acid, and chemical treatment reagent were put into the mixer according to the mass ratio of 50: 20: 80: 50: 100: 1: 3: 1: 5 and mixed for 5 minutes;

[0040] (5) Put the well-mixed dry powder, water, and vegetable foaming agent into the cement foaming machine accordi...

Embodiment 1

[0044]Corn stalks (plant diameter 1.8cm~2.6cm), No. 425 Portland cement and river sand for construction were used as matrix materials, and commercially available LX-N501 high-efficiency ammonia nitrogen remover was used as doping treatment reagent, which was applied in Jiangxi A farmland drainage ditch project in a river irrigation area. The manufacturing and engineering application process of the self-collapsing long-acting slow-release water purification filler brick is as follows:

[0045] (1) Naturally dehydrate the straw, remove the side leaves, put it into a pulverizer, and pulverize it into particles with a length of 1cm~1.5cm;

[0046] (2) Soak the crushed straw particles in a water glass solution with a modulus of 3.0 and a Baume degree of 50.0 for 30 minutes, then take it out and dry it naturally for 24 hours;

[0047] (3) Straw particles, sawdust, cement, fly ash, river sand, carboxymethyl cellulose, NaHCO 3 , citric acid, and high-efficiency ammonia nitrogen remo...

Embodiment 2

[0051] Sorghum straw (plant diameter 1cm~1.2cm), No. 425 portland cement and river sand for construction were used as matrix materials, and commercially available PCOD-2 COD degradation agent was used as doping treatment reagent, which was applied in a city in Nanjing For the river course project, since the river course is close to many living quarters, the water flow speed is slow, and the concentration of organic matter in the water body has always been high. The manufacturing and engineering application process of the self-collapsing long-acting slow-release water purification filler brick is as follows:

[0052] (1) Naturally dehydrate the straw, remove the side leaves, put it into a pulverizer, and pulverize it into particles with a length of 1cm~1.5cm;

[0053] (2) Soak the crushed straw particles in a water glass solution with a modulus of 3.0 and a Baume degree of 50.0 for 30 minutes, then take it out and dry it naturally for 24 hours;

[0054] (3) Straw particles, sa...

Abstract

The invention relates to a preparation device for a self-collapsible type long-acting and sustained release water quality purifying filler brick. The preparation device for the self-collapsible type long-acting and sustained release water quality purifying filler brick comprises a blank forming mould and a vibrating table, wherein the blank forming mould comprises an outer mould, core rods and a mould base, the outer mould is a hollow circular tube with the two ends open, five core rods are vertically arranged on the mould base, a limit slot is formed in the mould base, and the outer mould is connected with the mould base by virtue of the limit slot; and the vibrating table comprises a vibrating plate, supporting springs, a vibrating motor and a vibrating table support, wherein the vibrating motor is arranged below the vibrating plate, and the vibrating plate is connected with the vibrating table support by virtue of a plurality of supporting springs. The self-collapsible type long-acting and sustained release water quality purifying filler brick has the advantages that the self-collapsible type long-acting and sustained release water quality purifying filler brick can be slowly collapsed in water, the doped medicament is slowly released, and the self-collapsible type long-acting and sustained release water quality purifying filler brick is applicable to short-term emergency treatment of relatively seriously polluted water.

Description

technical field [0001] The invention relates to a preparation method and a preparation device of a self-collapsing long-acting slow-release water purification filler brick, belonging to the technical field of environmental protection materials. Background technique [0002] With the rapid development of my country's industrialization and the further improvement of agricultural intensification, industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of untreated or incompletely treated sewage is directly discharged into rivers, lakes and other water bodies, resulting in the overall deterioration of the water quality of rivers and lakes. At the same time, in rural areas, the excessive use of agricultural inputs such as chemical fertilizers and pesticides, and the unreasonable disposal of agricultural waste such as livestock and poultry manure, crop straw, and residual film on farmland have led to increasing...
