Embodiment 1

[0023] The waste water to be treated is sucked from the water tank by the lifting pump 2 through the raw water tank 1, and the flocculant is added by the peristaltic pump 5, and mixed with the sucked raw water in the pipeline mixer 8, and the water inlet mode of the pipeline mixer is lateral Water flows in so that the flocculant and waste water can be mixed quickly and effectively. The mixing time is 6-8 seconds. The mixed effluent directly enters the fiber ball filter column 10 through the connecting pipe, and the effluent enters the water storage tank 12.

[0024] A micro-flocculation-polyester high-elastic fiber ball filter algae removal equipment, including a raw water tank 1, a water storage tank 12 and a dosing tank 6, wherein the raw water tank 1 is connected to a pipeline mixer 8 through a lift pump 2, a valve 3, a flow meter 4 The dosing tank 6 communicates with the pipeline mixer 8 through the peristaltic pump 5, and the agitator 7 is installed in the dosing tank 6; t...

Embodiment 2

[0026] The raw water for the test was taken from the lake of Songjiang University Town, and the total number of algae was 6.8×10 6 ~8×10 6 Between, the turbidity is 8 ~ 15NTU, the water is sucked from the water tank by the lifting pump 2 through the raw water tank 1, and the flocculant polyaluminum chloride (PAC) is added by the peristaltic pump 5, and the dosage is 15mg / L. It is mixed with the sucked raw water in the pipeline mixer 8. The water inlet method of the pipeline mixer adopts side flow water, so that the flocculant and waste water can be mixed quickly and effectively. The mixing time is 6-8s, and the mixed water is passed through the connecting pipeline. Directly enter the fiber ball filter column 5, the filtration rate is 15m / h, the filtration cycle is 9h, and the effluent enters the water storage tank 12.

[0027] After 5 months of practical investigation, it was found that the whole system was running well, and the total number of algae in the effluent could be ...

Abstract

The invention relates to a filter and algae removal method by micro flocculation-terylene high elater fiber balls and equipment thereof. The method comprises: (1) the water to be treated and the flocculant which is added by a wriggle pump are mixed in an inflow pipeline in front of a fiber ball filter column, the water after mixing enters the fiber ball filter column, the filler of the filter column is terylene high elater fiber ball filter material, and the fiber ball filter column carries out reverse washing of low intensity at the end of the filter period; the equipment comprises an original water tank, a water storage tank and a drug adding groove, the original water tank is communicated with a pipeline mixer through a valve flow meter by a lift pump; the drug adding groove is communicated with the pipeline mixer by the wriggle pump, and a stirrer is installed in the drug adding groove; the apopore of the pipeline mixer sends the water to the water storage tank by the fiber ball filter column, and the terylene high elater fiber ball filter material is installed at the middle part of the filter ball filter column. By the terylene high elater fiber ball filter material with the characters of high porosity, large specific surface area, fast filter speed and strong pollutant stopping ability and long filter period, the effect on removing algae and turbidity substances in water is very obvious.

Description

technical field [0001] The invention belongs to the field of algae removal in water areas, and in particular relates to a micro-flocculation-polyester high elastic fiber ball filtration algae removal method and equipment thereof. Background technique [0002] In recent years, cyanobacteria blooms have occurred in many waters in China, and the water quality of water sources has been greatly damaged, seriously affecting the local domestic and production water. How to control high-algae source water is one of the major water pollution problems in the world today. [0003] At present, coagulation, pre-oxidation, air flotation, filtration and other treatment processes are mostly used in my country's production. However, these processes have certain limitations, and the algae removal effect is limited. For example, the main problem of the traditional coagulation process for treating high-algae water is the large amount of coagulant dosage and the large amount of sludge generated. ...
