摘要:- 深圳橫嶺污水廠二期（40×104 m3/d）工程原污水處理主工藝采用強(qiáng)化預(yù)處理加反硝化、硝化兩級(jí)曝氣生物濾池和紫外消毒工藝，
原出水水質(zhì)執(zhí)行一級(jí)A排放標(biāo)準(zhǔn)。2018年應(yīng)廣東省環(huán)保廳要求,啟動(dòng)地表準(zhǔn)Ⅳ類(lèi)提標(biāo)工程。同時(shí)，為改善現(xiàn)有系統(tǒng)預(yù)處理水力及固體負(fù)荷偏高，濾料破損、板結(jié)導(dǎo)致加大濾池水損及曝氣不均等運(yùn)行問(wèn)題，提標(biāo)工程設(shè)計(jì)采用新建濾池反沖洗水處理工藝以降低預(yù)處理負(fù)荷，主工藝流程為兩級(jí)曝氣濾池改造加新建反硝化濾池、新建高負(fù)荷混凝沉淀池工藝，實(shí)現(xiàn)深度脫氮及除磷要求。新建深度處理工段具有設(shè)計(jì)負(fù)荷高、節(jié)省占地、處理效果可靠、工藝先進(jìn)的特點(diǎn)，適用于用地受限的提標(biāo)工程。
Abstract:- The phase Ⅱ project of Shenzhen Hengling wastewater treatment plant (400 000 m3/d) adopted the enhanced pretreatment, denitrification, nitrification two-stage biological aerated filter and ultraviolet disinfection process, and the original effluent standard was required to reach the first level A. According to the request of Guangdong Provincial Environmental Protection Department, a quasi Ⅳ standard upgrading project was conducted in 2018. In order to solve the operation problems of high hydraulic and solid loading of pretreatment, filter water loss due to breakage and hardening of filter material, and uneven aeration, the upgrading project adopted the new filter backwash water treatment process to decrease the load of pretreatment. The main process included the renovation of the two-stage aeration filter and the construction of a new denitrification filter and a new high load coagulation sedimentation tank to realize the deep nitrogen and phosphorus removal requirements. The new advanced treatment section had advantages of high design load, low occupation of land, reliable treatment performance and advanced technology, which was suitable for land-restricted upgrading projects.
