Build a sedimentation tank at the construction site

Build a sedimentation tank at the construction site, first discharge the sewage into the sedimentation tank, remove suspended matter and oil substances and neutralize them, and then discharge them into the river after testing to meet the discharge standards.


During the drilling and pouring process, a screen is used to separate small gravel, sand and other solid particles in the mud, and the mud is discharged to the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank for full sedimentation. During the construction process, the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank are cleaned in time by an excavator, and the cleaned sediment is transported to the evaporation tank, and after natural dehydration and solidification, it is transported to the storage yard or the waste dump.


For the abandoned mud water, flocculants are added to the mud water. Since mud water is a suspended liquid containing a certain amount of fine mud particles in water, polymer flocculants are a type of water-soluble polymers. When mixed with mud water, the flocculants have the functions of bridging, netting, adsorption and electrical neutralization, which can destroy the stability of mud water and make mud particles quickly condense and settle from the water, thereby achieving the effect of mud-water separation.

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device.  The trommel screen  is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...
