Method for manufacturing water retaining/absorption dam for intercepting fire fighting wastewater

Abstract

The invention provides a method for manufacturing a water retaining / absorption dam for intercepting fire fighting wastewater. The invention is characterized in that the water retaining / absorption dam comprises an air bag (1) made of waterproof materials, an interlayer (3), a strap-shaped matter (8) filled with self-prepared viscous absorbent resins (11), and strap-shaped matters (9) and (10) filled with super absorbent resins and fibers; in the process of fire accident handling, the air bag (1) can be unfolded quickly along an area polluted by the fire fighting wastewater in the mode of air inflation or filler filling so as to intercept the fire fighting wastewater caused in an accident and improve the depth of the accumulated water, thereby facilitating pumping out the intercepted wastewater by utilizing a pump. By utilizing the method provided by the invention, field fixation and collection can be effectively carried out on the fire fighting wastewater containing complex organic toxicants, and the wastewater is prevented from seeping into the ground to pollute the water body; and the water retaining / absorption dam designed in a rolled mode has the advantages of quick paving speed, simple follow-up processing, safety, environmental friendliness and the like, and is convenient for transportation.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a water retaining and absorbing dam for intercepting fire-fighting waste water. Background technique [0002] Explosion accidents and fire accidents of different scales occur every year in our country, such as explosion and fire accidents in buildings, warehouses, factories, chemical industry areas, forests and other places, which generate a large amount of firefighting wastewater and become an important source of pollution. [0003] In particular, the fire-fighting wastewater in the chemical industry has a large amount of water, mixed with a large amount of various complex organic substances and toxic substances, and the composition is complex. If the control is not good, it will enter the urban water supply and drainage system, rivers, rivers, lakes, seas and groundwater systems, causing water environmental pollution. Pollution, the present invention is mainly used for on-s...

AI Technical Summary

Problems solved by technology

[0005] 1. In the case of explosion and fire, the firewall and drainage pipes are damaged, making it difficult to play the role of water retaining and drainage;

[0006] 2. Temporary earth dams have the problems of slow laying speed, leakage and adsorption pollution;

[0007] 3. Since pipelines are often buried underground at chemical accident sites, it will bring safety hazards to the soil taken from the site when building earth dams;

[0008] 4. It is difficult or too late to take soil to build an earth dam on site, so that the waste water flows to the outside world in a large area, and even flows into rivers, rivers, lakes, and seas, polluting water bodies;

[0009] 5. Earth was taken from the accident site to build the dam, which was labor-intensive

[0012] The flood control bag in the above-mentioned patent is not used for the interception of fire-fighting waste water because of the following defects:

[0013] 1. Fire-fighting wastewater, especially the lack of fire-fighting wastewater containing complex organic poisons in chemical emergency accidents. The water absorption of the resin used in the flood control bag in the above patent is sharply reduced, so the amount of resin is greatly increased, and the cost is too high;

[0014] 2. Ordinary super-absorbent resin, after absorbing water, there is no stickiness between the resins, and the flood control bag and the ground cannot be adhered together, so that there are gaps between the water-absorbing bags, between the water-absorbing bag and the ground, and between the resins to block water. poor effect;

[0015] 3. The flood control bag is filled with super absorbent resin. Compared with the flood control bag filled with sand, the volume and weight are relatively reduced, but the workload in use is still large;

[0016] 4. The flood control bag is filled with super absorbent resin. In the process of water absorption, only the resin that is exposed to water can be saturated in a short time. However, the pollution area formed by firefighting wastewater is large and the water is shallow. The overall water absorption rate of the flood control bag Very low, complicated to operate

[0017] At present, there is no effective technology to intercept fire-fighting wastewater, especially the lack of effective treatment methods for fire-fighting wastewater containing complex organic poisons in emergency accidents of petroleum, chemical and other enterprises
