Environmentally friendly "sludge solidifying agent"

Overview

A "sludge solidifying agent" that can quickly harden various silts and dust, seal waste heavy metal residues and greasy soil, prevent the dissolution of harmful substances, and effectively improve the structure of soil aggregates has been successfully developed in China, and its technical level has reached the international advanced level. .

Sludge solidifier introduces new substances and reacts with clay minerals to form a network structure, which can firmly bind soil particles or heavy metal waste and other substances. What is particularly surprising is that this curing agent can wrap heavy metals and organic matter into a network structure to block the dissolution of harmful substances, which not only ensures the growth of plants but also prevents soil erosion. Using soil solidifier to build roadbeds and road slopes not only allows for planting grass and flowers, but also prevents them from being washed away by heavy rains. For example, the sludge at the bottom of the river needs to be solidified. As long as the curing agent is mixed and used, the sludge at the bottom of the river will solidify, and sewage can be easily treated in the future.

In sewage treatment plants, a large amount of dewatered sludge containing toxic and harmful heavy metal residues needs to be processed in a timely manner every year. Because foreign curing agents are expensive, these sludges cannot be processed in large quantities. And every year, a large amount of treated sludge and waste are eagerly waiting to be disposed of as soon as possible. The new environmentally friendly material soil curing agent should be introduced to the market as soon as possible, so that this high-tech product can benefit mankind as soon as possible.

Characteristics of environmentally friendly sludge solidifier

1. Rapidly harden all kinds of silt and residual soil;

2. It can improve the soil aggregate structure;

3. It has the function of blocking heavy metals;

4. Has deodorizing effect;

5. Neutral, non-toxic and no secondary pollution.

Types of sludge solidifying agents

1. Soil conditioner - improves the aggregate structure of soil and turns it into normal soil;

2. Soil hardener - used to solidify the bottom mud of rivers and lakes in situ to prevent the dissolution of harmful substances; harden roadbeds, road slopes, house foundations and residual construction soil;

3. Waste solidifying agent - used to solidify oil sludge, oil soil, and sewage treatment plant sludge. It can block heavy metals and prevent harmful substances from dissolving;

4. Fly ash curing agent - special for fly ash, can be made into various fly ash products to realize resource reuse.

Application scope of sludge solidifying agent

1. Silt treatment in rivers, lakes and bays;

2. Early treatment and reuse of dredged soil;

3. Solidified sludge from urban sewage treatment plant sludge;

4. Reinforcement of roads, roadbeds and shoulders;

5. Soil improvement of accumulated silt in fish ponds and lakes;

6. Solidification treatment of oil sludge, oil soil and other wastes;

7. Soil improvement of golf courses;

8. Hardness reinforcement and soil improvement of residential land;

9. Eco-friendly park roads, lawn paving and soil improvement;

10. Solidification treatment of general industrial waste.
