Problems solved by technology

[0004] Sludge scraper is a kind of sludge discharge equipment, which is mainly used in sedimentation tanks in urban sewage treatment plants, water plants and industrial wastewater treatment. Among them, the chain plate type sludge scraper has high sludge discharge efficiency and simple structure. (motor reducer, transmission chain system), driven wheel (shaft) device, driving wheel (shaft) device, tensioning wheel (shaft) device, transmission chain and scraper, bracket, electric control box and other components, suitable for Rectangular settling tanks, rectangular primary settling tanks and rectangular secondary settling tanks greater than or equal to 6 meters. However, the width of the settling tank of the chain plate sludge scraper is limited by the scraper and is usually not more than 6m, and it is impossible to treat sludge with different characteristics.

Embodiment 1

[0041] A particle separation device such as Figure 1~3 As shown, it includes the left side mud scraper, the right side mud scraper, the scraper bracket 19 shared by the two mud scrapers and the combined mobile traction device. The two mud scrapers have the same structure and are arranged oppositely. Plate type mud scraper, and the mud scraping direction is opposite. The particle separation equipment is arranged in the sedimentation tank 1. The left side of the sedimentation tank 1 is provided with a perforated flower wall water inlet 23, which is the water inlet side, and the right side is provided with an outlet overflow tank 24, which is the water outlet side. Both sides are equipped with mud buckets 20, the rotary chain 3 of the left mud scraper rotates clockwise, the mud scraper 18 on the rotary chain 3 scrapes mud towards the water inlet side mud bucket 20, and the rotary chain 3 of the right mud scraper reverses Clockwise rotation, the mud scraper 18 on the rotary chai...

Embodiment 2

[0053] A kind of particle separation equipment, same structure as embodiment 1, this equipment is used for the treatment of phosphorus removal chemical sludge and inorganic fine sand and biochemical sludge mixed liquid, comprises the following steps:

[0054] (1) According to the process design parameters, the service length of the left mud scraper and the right mud scraper is pre-configured, and the assembly is preset according to the centering method.

[0055] (2) The mixed liquid containing phosphorus removal chemical sludge and inorganic fine sand and biochemical sludge enters the sedimentation tank 1 from the water inlet 23 of the perforated flower wall on the left.

[0056] (3) The chemical sludge and inorganic micro-sand sludge with a large specific gravity settle quickly and distribute in the range of the left sludge scraper, and the specific gravity of biochemical sludge is close to that of water, and the sedimentation speed is slow to distribute in the range of the ri...

Abstract

The invention relates to particle separation equipment and a use method thereof. The particle separation equipment comprises two chain plate type mud scrapers respectively arranged on the water inlet side and the water outlet side of a sedimentation tank (1), the bottoms of the two mud scrapers are provided with combined movable traction wheels (2), and the combined movable traction wheels (2) are simultaneously connected with two mud scrapers. Compared with the prior art, the equipment has the advantages that the sludge is scraped in different areas, and the target sludge is separated according to quality.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a particle separation device and a use method thereof. Background technique [0002] In the water treatment process, sedimentation separation is widely used in activated sludge sludge water separation, coagulation sedimentation chemical sludge separation and other processes. During separation, the sedimentation process usually does not distinguish the characteristics of the sludge, and the settled sludge is collected and mixed for treatment. [0003] With the continuous emergence of various new sewage treatment processes such as activated sludge process, granular sludge process, heavy powder carrier enhanced water treatment process, granular sludge flocculent sludge composite process, and in-situ chemical phosphorus removal process in biochemical pools, sewage The sludge in the reactor gradually exhibits multiple composite characteristics, so it must be strictly separate...
