Stone material sewage treatment system and method thereof

Abstract

The invention discloses a stone material sewage treatment system and a treatment method thereof. The sewage is characterized in that sewage is filtered by a residue blocking grill, filtered sewage flows into a sewage pool, sewage in the sewage pool is injected to a sewage pipe by a sewage pump, a flocculating agent is injected to the sewage pipe by a metering pump, and the sewage pipe and a sewage tower are communicated to make sewage containing the flocculating agent flow into the bottom in the sewage tower; a solenoid valve is arranged at the bottom of the sewage tower, a grill used for blocking the rise of sludge is arranged in the sewage tower, a solenoid valve is arranged at the bottom of a water purification tower, and a purified water outlet is arranged at the top of the water purification tower; and the solenoid valve at the bottom of the sewage tower and the solenoid valve at the bottom of the water purification tower are respectively communicated with the sewage pool, and the running of each of the sewage pump, the metering pump, the solenoid valves and the sludge pump is controlled by a central controller. The stone material sewage treatment system disclosed in the invention has the advantages of small occupied area, automatic running under the control of the central controller, simple operation, and small manpower demand; and the sewage treatment method disclosed in the invention has the advantages of fast sewage treatment speed, good quality of purified water obtained after the treatment, and high cyclic utilization rate.

Description

technical field [0001] The invention relates to a treatment system and method for waste pollutants, in particular to a stone sewage treatment system and method. Background technique [0002] Stone deep-processing enterprises are large consumers of water resources. The sewage generated during the production process contains a large amount of suspended solids, which will cause serious water pollution after discharge. [0003] The stone sewage treatment methods in the prior art mainly include: pipe sedimentation tank method, advection sedimentation tank method, host sedimentation method, drum concentration and dehydration integrated machine method, although these methods can realize the purification and circulation of stone sewage to a certain extent However, there are still problems such as large floor area, complicated operation, easy sediment compaction, difficult to clean up, large manpower demand, high labor intensity, poor treatment effect and low recycling rate. Conten...
