Example Embodiment

[0021] Such as figure 1 As shown, a process method for wastewater treatment of a natural material sand and gravel processing system includes the following steps:

[0022] 1) The waste water from the natural material sand and gravel processing system is collected and transported to the collection and distribution well 2 through the canal 1 and distributed from the collection and distribution well 2 to the wastewater sedimentation tank 3 for natural precipitation;

[0023] 2) In step 1), the suspended solids in the natural sedimentation wastewater settle to the bottom of the wastewater sedimentation tank 3, and the supernatant that meets the discharge standard is discharged into the river water 5 through the drainage ditch 4 connected with the wastewater sedimentation tank 3.

[0024] The wastewater sedimentation tank 3 is the waste slag storage yard of the natural sand and gravel processing system.

[0025] The wastewater sedimentation tank 3 is a stone masonry structure or an earth-ro...

Abstract

The invention relates to a technological method for processing natural material sandstone processing system waste water. The method comprises steps that: (1) waste water of natural material sandstone processing systems is gathered, and is delivered into a collected water distributing well by using a trench pipe; the waste water is delivered into a waste water sedimentation tank by the collected water distributing well, and is subject to natural sedimentation; (2) suspended matters in the waste water processed through natural sedimentation in the previous step are settled to the bottom of the waste water sedimentation tank, and a supernatant which reaches a discharging standard is discharged into river water through a water discharging ditch communicating with the waste water sedimentation tank. According to the technological method for processing the natural material sandstone processing system waste water, the waste water sedimentation tank is adopted as a waste slag storing site, such that a mechanical dredging equipment structure of the sedimentation tank is saved; the waste water is continuously processed, and no drying time is required, such that the utilization rate of a unit tank is high; the waste water reaching a discharging standard after processing is not recovered and reused, such that the construction investment of facilities such as a recovering technological pipe and a sedimentation tank is saved. Therefore, the waste water processing efficiency is improved, the cost is reduced, the operation is convenient, and the method is economic and reliable.

Description

technical field [0001] The invention relates to a wastewater treatment process, in particular to a process method for wastewater treatment of a natural material sandstone processing system. Background technique [0002] The natural material sand and gravel processing system is usually arranged near the wharf, and the water intake is convenient and economical. The wastewater treatment has the following characteristics: [0003] 1. The sedimentation speed of suspended matter in wastewater is fast, and the discharge standard can be reached after one day of natural precipitation; [0004] 2. Wastewater that reaches the discharge standard after treatment does not need to be recycled. [0005] At present, the wastewater treatment processes of natural material sand and gravel processing systems mainly include radial flow sedimentation tank process, mechanical press filter process, tailings pond process, vacuum filtration process, urban sewage treatment process and large storage ca...
