Stone cutting wastewater resourceful treatment system

Abstract

The invention discloses a stone cutting wastewater resourceful treatment system. The stone cutting wastewater resourceful treatment system comprises a wastewater ore-dressing device, a coarse sand settling and water discharging device and a fine sand settling and sand discharging device. The wastewater ore-dressing device comprises a water-distributing and ore-stopping device, and a magnetic picking belt is rotatably arranged below the water-distributing and ore-stopping device. The coarse sand settling and water discharging device comprises a coarse sand settling tank, and a spiral coarse sand conveying device is arranged at the bottom of the coarse sand settling tank. A sand-stopping baffle plate is arranged in the coarse sand settling tank, and a fine sand wastewater discharging chamber is formed between the sand-stopping baffle plate and the coarse sand settling tank and is provided with a fine sand wastewater delivery device. The fine sand settling and sand discharging device comprises a fine sand settling tank, and a fine sand wastewater distributing device and a fine sand settling baffling device are arranged on the inner upper portion of the fine sand settling tank. The stone cutting wastewater resourceful treatment system is capable of achieving graded recycling of iron powder, coarse sand and fine sand in wastewater and is beneficial to stone cutting wastewater resourceful treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a stone cutting sewage resource treatment system. Background technique [0002] The treatment of sawing sludge in the stone industrial park has always been the focus of environmental protection concerns of various production enterprises and the government, and a complete set of comprehensive treatment equipment for stone cutting sewage has gradually appeared on the market. However, due to the large cost and high operating costs of the existing comprehensive treatment equipment, some enterprises do not have such comprehensive sewage treatment equipment, but use various methods to settle the saw mud sewage, and the waste water and saw silt cannot be recycled. Utilization will pollute the environment more; and the processed sand is the best purified water resource in the river. Over the years, many river courses have lost sand, which has caused great harm to the ...
