In the production process, the sand washing plant is bound to have a large amount of sediment discharge. For every sand washing plant, the treatment of mud water is not a small problem. If the muddy water is directly discharged into the river without treatment, a large amount of solid matter will be directly discharged into the river, resulting in river siltation and water pollution.

In the production process, the sand washing plant is bound to have a large amount of sediment discharge. For every sand washing plant, the treatment of mud water is not a small problem.
If the muddy water is directly discharged into the river without treatment, a large amount of solid matter will be directly discharged into the river, resulting in river siltation and water pollution.
Therefore, whether it is for environmental protection considerations, or in order to deal with the inspection of relevant departments, how to better deal with sewage, mud and water separation is a very important matter.
How is the sand washing site separated from mud and water?
At present, mud and water separation generally has the following two ways:
1. Mechanical treatment
Mechanical treatment is very common in the process of mud and water separation, which can be said to be standard for mud and water separation. However, there are many types of machinery that can be used for mud water treatment, and different machines have their own advantages and disadvantages for different mud water.
Now the construction site is a common two-stage cyclone equipment of the mud-water separation system. However, in order to save costs, many equipment has castrated some cyclones, so sediment accumulation in mud sedimentation tanks is often seen, and special mechanical equipment must be used to excavate to ensure the normal operation of the whole system.
There are also centrifuges that can directly precipitate soil by centrifugal action, and a mud-water separation system integrating a tailings dry drainage system with a box filter press, ordinary sand irrigation and a belt filter press.
But no matter what kind, mechanical treatment of muddy water has a problem that cannot be bypassed-price. The price of a set of mud-water separation equipment is often very expensive, and it costs millions of yuan to start, which is not a small investment.
At the same time, although the mechanical treatment scheme has the advantages of clean working environment, energy saving and medicine saving, low overall operating cost, small footprint, low labor intensity, etc., the disadvantage is that it is not widely used, requires high mud properties, and is easy to block.
2. Pharmaceutical treatment
Pharmaceutical treatment is a more general solution than mechanical treatment.
The use of polyaluminium chloride, polyacrylamide and other flocculants to treat the sludge can effectively flocculate the sludge in the sludge.
Such as polyacrylamide, through the flocculation of polyacrylamide in the sludge between the individual particles of bridging, so that the polymer chain segments adsorbed on different particles, promote the aggregation of particles, to achieve the effect of rapid mud-water separation.
