The secondary treatment stage is primarily biological, relying on microorganisms to break down organic matter. However, several chemicals are still employed to enhance this process. For instance, flocculants like polyacrylamide may be used to promote the settling of biomass, facilitating easier removal of residual sludge. Additionally, nutrient management is critical during secondary treatment, as excess nitrogen and phosphorus can lead to water bodies’ eutrophication. To address this, chemicals such as ammonium sulfate or magnesium hydroxide may be introduced to balance nutrient levels and avoid environmental imbalances.

Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction

There are many kinds of specifications for crack resistant welding mesh used in the construction industry. The commonly used specifications are as follows:
- Large aperture hexagonal net is widely used in mountain, embankment protection, railway and highway isolation barrier, river channel management, soil consolidation berm, water conservancy engineering construction, rivers, DAMS and seawall anti-erosion protection and reservoir river interception, animal husbandry, grassland isolation guardrail, etc.
- The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.

2) wire spacing: we all know that the smaller the wire spacing, the stronger the cage, in fact, too close is not good, too close to the dog will have a feeling of repression, we recommend that you buy wire spacing between 15-25mm, so it is not too close, and not too loose.

The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.

Large hexagonal net is called stone cage net, mainly used for mountain protection, hydraulic construction, etc. Small wire hexagonal net is used as a good breeding material, the twisted flower hexagonal net in the welding of the iron frame get on the hexagonal net burning welding coops, pigeonholes, rabbit cages and other cage, hexagonal net is the best breeding material with the net.

The parameters to be provided are as follows:
- In the selection of birdcage, the characteristics of the birds, the way of daily management, the impact of the surrounding environment and so on should be considered. Therefore, it is necessary to have requirements on the shape, structure and technology of the cage, so that the cage can not only be suitable for the birds’ activities, but also delicate and beautiful.

Advantages: The cost of hot dip galvanized rust prevention is lower than that of other paint coating. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair. Galvanized layer and steel is a metallurgical connection, into a part of the steel surface, so the durability of the coating is more reliable.
- The mixture of rare earth and aluminum enhances the fluidity of zinc liquid, makes the coating more uniform, and also reduces the zinc consumption. Hot dip galvanized wire has better protection performance than cold galvanized wire, which makes it good application in chemical experimental equipment. Hot dip wire coating thicker, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot dip galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.

Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.

The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
- In order to adapt to the living habits of different birds, ornamental cages can be roughly divided into two types of bird cages, namely cereal and insectivorous cages. Cereal bird cage with canary cage, yellow bird cage, wenbird cage, bird cage, hydrangea cage, insect-eating bird cage with thrush cage, chin cage, myna cage and so on.
-
The barbed wire factory will store the inventory of the barbed wire blade in the appropriate place because of the understanding of the product characteristics.
-
One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
-
The thorn rope belongs to the weaving industry, so it is less affected by environmental protection. The thorn rope will not be discarded in the production process, and it belongs to the weaving industry, so the situation is less affected by environmental protection.

The application of cold wire drawing is very wide today. What problems need to be paid attention to in the acceptance of cold wire drawing in galvanizing plant?
- Spray hook net wholesale used in the stadium, mainly used to play the role of the game ball isolation block, the field isolation zone. Stadium Seine usually use woven net as the main raw materials, it is different from welding net, woven mesh with mesh uniform, flexible, convenient and has good elasticity, impact resistance, etc. Product characteristics, the stadium fence is divided into two categories, category is packaged stadium fence, also known as Seine bulk type, another kind is with a border plastic spraying hook flower wholesale network. Both kinds of stadium purse Seine have advantages and disadvantages.
- The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
