Description

Technical Field

[0001] This utility model relates to the field of algal sludge treatment technology, specifically a treatment system that uses ferric chloride and modified bamboo powder to condition algal sludge. Background Technology

[0002] With the acceleration of urbanization, eutrophication of water bodies is becoming increasingly serious, leading to the proliferation of cyanobacteria and the formation of algal sludge. Traditional algal sludge treatment methods suffer from low dewatering efficiency, heavy environmental pollution, and low resource utilization. Therefore, developing a novel algal sludge treatment system is of great significance for improving environmental quality and increasing resource utilization efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a treatment system for algal sludge using ferric chloride and modified bamboo powder, which can conveniently and efficiently treat algal sludge.

[0004] The technical solution is as follows: a treatment system for conditioning algal sludge using ferric chloride and modified bamboo powder, characterized in that it includes a sludge receiving tank and an algal sludge receiving tank, the outlets of which are respectively connected to a sludge storage tank and an algal sludge storage tank. The volume of the sludge storage tank is twice that of the algal sludge storage tank. The outlets of both the sludge storage tank and the algal sludge storage tank are connected to the inlet of the conditioning tank. A ferric chloride dosing tank and a modified bamboo powder dosing tank are also provided next to the conditioning tank. The outlet of the conditioning tank is connected to the inlet of a plate and frame filter press. The liquid outlet of the plate and frame filter press is connected to a wastewater treatment plant. A sludge storage bin is provided next to the plate and frame filter press.

[0005] A further feature is that the bottom outlet of the sludge storage silo is connected to an inclined discharge chute;

[0006] Both the ferric chloride dosing tank and the modified bamboo powder dosing tank include a main tank and a backup tank.

[0007] By adopting this utility model, sludge and algal sludge are mixed at a volume ratio of 2:1 and then fed into a conditioning tank. Ferric chloride and modified bamboo powder are added through a dosing tank to improve dewatering and sludge calorific value. Solid-liquid separation is then achieved using a plate and frame filter press. The sludge cake is recycled to a sludge storage silo for subsequent incineration, while the filtrate is sent to a wastewater treatment plant for further treatment. This method enables convenient and efficient treatment of algal sludge. Attached Figure Description

[0010] See Figure 1 , Figure 2 As shown, a treatment system for conditioning algae sludge using ferric chloride and modified bamboo powder includes a sludge receiving tank 1 and an algae sludge receiving tank 2. The outlets of the sludge receiving tank 1 and the algae sludge receiving tank 2 are respectively connected to a sludge storage tank 3 and an algae sludge storage tank 4. The volume of the sludge storage tank 3 is twice the volume of the algae sludge storage tank 4. The outlets of both the sludge storage tank 3 and the algae sludge storage tank 4 are connected to the inlet of a conditioning tank 5. A ferric chloride dosing tank 6 and a modified bamboo powder dosing tank 7 are also provided next to the conditioning tank 5, allowing the addition of the corresponding chemicals, ferric chloride and modified bamboo powder, into the conditioning tank 5. Both the ferric chloride dosing tank 6 and the modified bamboo powder dosing tank 7 are equipped with a main tank and a backup tank to achieve uninterrupted dosing.

[0011] The outlet of the conditioning tank 5 is connected to the inlet of the plate and frame filter press 8, and the liquid outlet of the plate and frame filter press 8 is connected to the sewage treatment plant 9. The filtrate directly enters the sewage treatment plant 9 for treatment to meet the tertiary discharge standard. A sludge storage silo 10 is set up next to the plate and frame filter press 8. The sludge cake pressed out by the plate and frame filter press 8 can be stored in the sludge storage silo 10 and finally transported out for co-firing.

[0012] The bottom outlet of the mud storage bin 10 is connected to an inclined discharge chute 11, which can conveniently discharge the mud cake and facilitate its transport to the incineration site.

[0013] This application adds ferric chloride and modified bamboo powder to the conditioning tank 5. The modified bamboo powder includes S-BF (bamboo powder modified with stearic acid) and KH-BF (bamboo powder modified with KH-500). The introduction of stearic acid makes the surface of S-BF (stearic acid modified bamboo powder) more hydrophobic, which helps to bind with oily substances in algae. Hydrophobicity can promote the adsorption of organic matter and improve the flocculation ability of algal sludge. The long-chain fatty acid structure formed by stearic acid can enhance the adhesion of the complex and help the interaction between sludge particles, thereby enhancing the flocculation effect.

[0014] The introduction of KH-500 (aminosilane) increases the number of amino and hydroxyl functional groups on the surface of KH-BF (KH-500 modified bamboo powder). These polar functional groups effectively adsorb water molecules and enhance the binding with polar substances in sludge. The hydrophilic properties of KH-BF help form a good aqueous phase, promoting the binding and precipitation of heavy metals and organic matter in the aqueous phase, thereby effectively improving the flocculation effect.

[0015] Ferric chloride, a common flocculant, can work in conjunction with modified bamboo powder to promote the aggregation of sludge particles through charge neutralization and bridging effects, thereby improving the conditioning effect.

[0016] Ultimately, this improved the dewatering efficiency of algal sludge and reduced treatment costs; reduced environmental pollution and improved the resource utilization of sludge; and increased the calorific value of sludge through the use of modified bamboo powder, providing a new approach for the energy utilization of sludge.
