Embodiment approach

[0026] The back-and-forth anti-suction fiber filter of the present invention has two kinds of implementation modes: one is the back-and-forth lifting anti-suction fiber filter, and the other is the back-and-forth horizontal back-suction fiber filter, two implementations below The working principle of the method is explained separately:

[0027] A sewage treatment method for a back-and-forth back-suction fiber filter. The back-and-forth back-suction fiber filter adopts a back-and-forth lifting back-suction fiber filter, and all filter holes are arranged symmetrically in two groups along the horizontal direction. A group of mud suction devices are installed at the front end of each group of filter plates. Under the limit action of the lifting guide rail and the driving action of the lifting mechanism, the suction head of the mud suction device is flush with the filter plate and abuts against the front of the filter cloth. Its movement track is parallel to the filter plate, and t...

Embodiment approach 1

[0081] For small-scale sewage treatment systems, the structure of a back-and-forth lifting back-suction fiber membrane filter involved in Embodiment 1 of the present invention is as follows: Figure 1-12 As shown, it includes a water inlet tank 1, a sewage tank 2, a filtrate tank 3, a water outlet tank 4, two groups of filter plates 5A and 5B, two groups of mud suction devices 6A and 6B, 6A and 6B, a lifting mechanism 7, lifting guide rails 8A, 8B and 8C, limit sensor 9, liquid level sensor 10 and sedimentation sludge pump 11 and other parts. The water inlet tank 1 is located at the front end of the sewage tank 2, and the sewage flows into the sewage tank 2 slowly and steadily through the water inlet between the water inlet tank 1 and the sewage tank 2; the sewage tank 2 is a rectangular structure, and a slope is provided at the bottom to make sediment The sludge is concentrated, which is convenient for suction and cleaning; the back end of the sewage pool 2 is connected to th...

specific Embodiment approach 2

[0086] For some large sewage treatment systems, multiple filter plates and multiple mud suction devices can also be used. The specific structure is as follows: Figure 11 , 12 shown. Its main structure is consistent with the specific embodiment 2, and its main difference from the specific embodiment is that each filter plate 5A01, 5A02, ..., 5A0m, 5B01, 5B02, ..., 5B0m corresponds to a dredge 6A01, 6A02 , ..., 6A0x, 6B01, 6B02, ..., 6B0x; each mud suction device 6A01, 6A02, ..., 6A0x, 6B01, 6B02, ..., 6B0x is connected with a stay rope, and the stay rope 704 passes through the The pulley is connected with the lifting drive 702, driven by the lifting drive 702, the mud suction devices 6A01, 6A02, ..., 6A0x, 6B01, 6B02, ..., 6B0x move at a constant speed, bounded by the horizontal center of the filter plate group, on the same side The movements of the mud suction devices 6A01, 6A02, ... 6A0x or 6B01, 6B02, ..., 6B0x are synchronized and consistent, and the movements of the mud...

Abstract

The invention relates to a returning back suction type fiber filter and a sewage treatment method thereof. Filtering holes are symmetrically formed between a sewage pool and a filtrate tank; filteringplates are fixedly arranged on the filtering holes; sewage in the sewage pool is filtered by the filtering plates and then enters into the filtrate tank; sludge absorbers are arranged on one side ofthe filtering plates on the sewage pool; the sludge absorbers respectively do lifting or horizontal synchronous reverse sludge-absorbing motion under the action of driving mechanisms; when the filtering plates are blocked, the liquid level of the sewage in the sewage pool rises; when the liquid level of the sewage in the sewage pool reaches the liquid level set by a liquid sensor, the sludge absorbers are controlled and started to back suck the sludge on the filtering plates, and meanwhile, the driving mechanisms are started to drive the two sets of sludge absorbers to do lifting or horizontalsynchronous reverse sludge-absorbing motion, so as to suck the sludge on the filtering plates and recover the filtering capacity of the filtering plates. The sewage treatment device provided by the invention is low in cost, is high in sewage treatment capacity and has an excellent sewage treatment effect.

Description

technical field [0001] The invention relates to sewage treatment technology in the field of environmental protection, in particular to a back-and-forth back-suction fiber filter tank and a sewage treatment method thereof. Background technique [0002] my country's water shortage situation has gradually emerged since the 1980s, and with the passage of time, the situation has been increasing year by year. In order to solve the problem of water shortage, it is necessary to adopt measures to reduce expenditure and increase revenue at the same time. Measures such as long-distance water diversion, seawater utilization, and sewage resource utilization are adopted to increase revenue. However, the cost of long-distance water diversion and seawater utilization is high, and relatively speaking, the utilization of sewage resources is a more economical way. [0003] The State Environmental Protection Administration promulgated and implemented the "Pollutant Discharge Standards for Urba...
