Polyacrylamide is widely used in the field of sewage treatment and plays an important role in the treatment and disposal of sludge. However, with the increasing environmental requirements and the increase in waste disposal costs, it is also important to understand the cost of polyacrylamide sludge disposal.
1. Sludge yield coefficient per 10,000 tons: (for those who do not give specific data in the feasibility study, it is estimated accordingly).
SS is less than 100, and the coefficient is 10；SS is between 100 and 200 with a coefficient of 13；SS is greater than 200, and the coefficient is 16. That is: 10,000 tons of aquatic products 20% dry mud 16 tons, converted to 80% moisture content of mud is 16/0.2 = 8 tons. Converted to 60% moisture content of mud is 4 tons.
2. Example of mud and water conversion relationship:
1) The moisture content of 1 ton of sludge is 80, which becomes 0 after dryingHow to calculate the moisture content of 5 tons of sludge?
Re: 0 when dry5 tons of sludge, i.e. 0The original moisture content of 5 tons of water is 80%, that is, there is 08 tons of water, 03 tons of water with a moisture content of 03÷0.5=60%
2) The relationship between the amount of absolute dry sludge and the amount of treated water and the concentration, the amount of absolute dry sludge is equal to the amount of treated water of the equipment multiplied by the concentration of sludge:
For example, the water treated by the equipment is 10m3 h, and the sludge moisture content is 995%, the relative sludge concentration is 05%。The amount of absolute sludge of the equipment is 10*0005*1000=50kg。Multiplying the amount of water treated by the sludge concentration and multiplying it by 1000 equals how many kilograms per hour are treated. This translates to 50kg h.
Knowing the amount of absolute dry sludge to calculate the amount of water treated, the calculation method of the equipment is to divide the amount of absolute dry sludge by the sludge concentration (1-moisture content), for example, the amount of absolute dry sludge treated by the equipment is 60kg h, the moisture content is 99%, and the amount of water treated is 60 (1-099) = 6000kg, one ton is equal to one thousand kilograms, so it is equal to 6t h.
3. The relationship between the moisture content and density of sludge:
4. Units that absolutely dry sludge.
The unit of absolute dry sludge is kgds d, and the empirical value of pam cation dosage is 4g kgds.
5. Sludge disposal fee.
The above is the calculation of the amount of sludge, the sludge disposal fee is generally charged by the ton, according to the local industry situation, in addition to the sludge disposal fee also includes the sludge transportation fee, some disposal companies are responsible for transportation, the transportation fee is incorporated into the disposal fee.
The cost of polyacrylamide sludge disposal is a slightly more complex issue and involves multiple links and factors. Understanding and evaluating these costs is critical to developing effective sludge disposal strategies and decisions. For the choice of polyacrylamide, the industry reputation is better Guangdong Shouxin Environmental Protection, if you need it, you can learn about it. By considering the cost and benefit, the polyacrylamide sludge disposal process can be optimized to achieve efficient use of resources and sustainable environmental development.
