Several factors determining the total cost of sludge disposal.

      Since 2018, with the intensive introduction of China’s environmental protection policies, environmental protection efforts have been further increased. Environmental protection policies and measures have been extended from administrative means to legal, administrative and economic means, and the enthusiasm and initiative of pollution control enterprises have been fully mobilized. As for the sand industry, the problem of sewage treatment of sand washing plant has been widely concerned by the whole industry. It is more and more important to treat the sand washing sewage to realize environmental protection production and pollution-free discharge!

      When it comes to the importance of sand washing wastewater treatment, it has to be said that the reason why most sand plant operators have poor enthusiasm for sand washing wastewater treatment is that the cost of sludge free treatment is too high. As a by-product of sewage treatment, sludge has the characteristics of high concentration, high pollution and difficult treatment. If it is not properly disposed, it will not only fail to achieve the purpose of environmental protection, but also cause more serious pollution to the environment.

      Therefore, how to save the cost of sludge disposal as much as possible has become a problem that the operators of sand farms are exploring. Before analyzing how to save energy sludge disposal cost, first of all, we need to know what factors determine the total cost of sludge disposal. Next, Doyen China will briefly introduce some factors that determine the total cost of sludge disposal.

1. Various expenses in sludge disposal process

     The cost of sludge disposal includes: sludge transportation cost, site cost, sludge drying cost, etc. The cost of sludge drying includes electricity cost, depreciation cost of sludge treatment equipment, labor cost, management cost, etc. In terms of transportation cost, the transportation cost is relatively less when the disposal site is near, and higher when the transportation location is far away, so there are some differences in this part.

2. Sludge treatment equipment used

     If the energy consumption of sludge treatment equipment used in the project is very low, it can save a lot of expenses for the project with a daily sludge treatment capacity of more than 100 tons. In addition, compared with the mechanical sludge treatment equipment, the automatic sludge treatment equipment only needs one person to supervise multiple sludge treatment production lines. Today, with the increasing labor cost, the intangible cost of treatment is also saved. In addition, if the enterprise chooses the deep dehydration treatment equipment, not only the reduction of sludge volume is obvious, but also the later transportation cost and sludge disposal cost will be reduced correspondingly.

3. Design of sludge treatment scheme

     At present, the sludge disposal plan in China tends to be resource-based utilization, and sludge composting, sludge incineration heating power generation, sludge brick making, cement making and other plans occupy the mainstream. When the sludge treatment plan is determined, the approximate cost range of sludge treatment is also basically determined. For example, sludge landfilling includes sludge drying, sludge transportation cost, landfill use cost, etc., and the standard sludge landfill treatment cost is about 200 yuan / ton; sludge incineration cost is about 100-300 yuan / ton, but accompanied by high resource value; sludge composting treatment cost is 90-150 yuan / ton.
