Embodiment Construction

[0033] Please refer to the attached figure 1 Shown, the present invention is a kind of carbon sand filter tank, and it is made of left pool body 1, right pool body 2, water inlet channel 3, filter plate 4, support plate 5, quartz sand layer 6, activated carbon layer 7, water outlet channel 8 And several parts such as roofing 9 form.

[0034] Wherein, the left pool body 1 and the right pool body 2 are arranged side by side and communicated with each other. The inner walls of the left pool body 1 and the right pool body 2 are provided with an anti-corrosion layer 100;

[0035] The upper part of the left pool body 1 and the right pool body 2 is provided with several water distribution tanks 10;

[0036] The filter plate 4, the supporting plate 5, the quartz sand layer 6, and the activated carbon layer 7 are arranged sequentially from the bottom of the left pool body 1 from bottom to top. Due to the rough surface structure of activated carbon 7, it can accommodate a large amoun...

Abstract

The invention relates to a carbon-sand filter tank. The carbon-sand filter tank comprises a left tank body, a right tank body, a water inlet channel, a filter board, a supporting board, a quartz sand layer, an activated carbon layer, a water outlet channel and a roof; the left tank body and the right tank body are arranged side by side, and are communicated; anti-corrosive coatings are arranged on inner walls of the left tank body and the right tank body; a plurality of water distribution slots are formed in the upper parts in the left tank body and the right tank body; the water distribution slots are connected with the water inlet channel for discharging water into the left tank body and the right tank body; the filter board, the supporting board, the quartz sand layer and the activated carbon layer are sequentially arranged on the bottom of the left tank body from bottom to top; aeration holes are formed in the right tank body; the water outlet channel is enclosed at the outer sides of the left tank body and the right tank body, and a water outlet flashboard is arranged among the water outlet channel, the left tank body and the right tank body; and the roof is erected on the tops of the left tank body and the right tank body by a plurality of framework columns. The carbon-sand filter tank disclosed by the invention has the advantages such as a simple structure, good ammonia nitrogen removal effect, high removal speed, low treatment cost and the like.

Description

【Technical field】 [0001] The invention relates to drinking water treatment equipment, in particular to a construction method of a carbon sand filter tank and an anticorrosion layer thereof, and belongs to the technical field of water treatment equipment. 【Background technique】 [0002] Ammonia nitrogen is one of the main pollutants in my country's surface water bodies, and the conventional process of "coagulation-sedimentation-filtration-disinfection" adopted by most waterworks in my country has very limited removal effect on ammonia nitrogen, so it is difficult for the factory water to meet the "Life Drinking Water Sanitation Standards (GB 5749-2006) requires that ammonia nitrogen effluent is less than 0.5mg / L. [0003] On the basis of the conventional process, the activated carbon biological treatment process is added, through the abundant biomass and relatively sufficient oxygen, the efficient removal of ammonia nitrogen can be achieved, and the quality of the factory wate...
