江蘇蘇州天通一體化污水處理設(shè)備
工程概況
本污水處理系統(tǒng)污水來源為生活污水,生活污水如果直接排放會污染周邊環(huán)境,因此必須對排放的污水進(jìn)行處理,使處理后的排放水達(dá)標(biāo)排放。 根據(jù)實際情況,針對本處理工程,在處理工藝上采用AO處理技術(shù),工藝成熟,處理效果好,處理后的排放水可達(dá)到國家《污水綜合排放標(biāo)準(zhǔn)》(GB8978-1996)一級排放標(biāo)準(zhǔn)。
設(shè)計依據(jù)
1、《城市區(qū)域環(huán)境噪聲標(biāo)準(zhǔn)》(GB3096-93); 2、《室外排水設(shè)計規(guī)范》(GBJ14-87); 3、《給水排水工程結(jié)構(gòu)設(shè)計規(guī)范》(GBJ69-84); 4、《污水綜合排放標(biāo)準(zhǔn)》(GB8978-1996)。
設(shè)計范圍
污水處理站范圍內(nèi)的污水處理建(構(gòu))筑物及配套建(構(gòu))筑物的工藝、土建、電氣、儀表及供電線路及進(jìn)出水管線的設(shè)計。
工藝選擇
水質(zhì)濃度不高且穩(wěn)定,可生化性較好,屬可生化污水。工藝確定
工藝可分為生物掛膜法和活性污泥法。生物掛膜法一般適用于水量較小、水質(zhì)較為穩(wěn)定、濃度不高的污水水質(zhì),同時由于生物膜培養(yǎng)較快系統(tǒng)調(diào)試好后運行穩(wěn)定,可操作性較強(qiáng)。
由于污水中氨氮和有機(jī)物含量較高,建立調(diào)節(jié)池的目的是調(diào)節(jié)污水的數(shù)量和質(zhì)量。A級池的生化作用后,仍存在一定量的有機(jī)質(zhì)和較高的氮和氨氮污水中。為了進(jìn)一步氧化和分解有機(jī)物,同時,當(dāng)炭化效果趨于完整時,硝化反應(yīng)可以順利進(jìn)行。特別是在生物有機(jī)物氮、有機(jī)物、氨氮等有機(jī)物的生物降解中,氨氮也是污染控制的重要指標(biāo)之一,因此污水處理采用厭氧好氧A/O生物接觸氧化工藝,生化池需要分為池池和O池兩部分。
Design scope
The design of sewage treatment, construction, construction and construction, construction, electrical, instrument, power supply line and inlet and outlet water line of sewage treatment station.
Process selection
The water quality is not high and stable, and it can be biodegradable, which is a biodegradable sewage. Process determination
The process can be divided into biological membrane method and activated sludge process. Biofilm is generally suitable for sewage with small water quality, stable water quality and low concentration. At the same time, because biofilm culture is faster and system debugging is good, operation is stable, and operability is strong.
Because of the high content of ammonia nitrogen and organic matter in the sewage, the purpose of setting up the regulating pool is to adjust the quantity and quality of the sewage. There is still a certain amount of organic matter and higher nitrogen and ammonia nitrogen sewage after the biochemical action of the A-level pool. In order to further oxidize and decompose organic matter, the nitrification reaction can be carried out smoothly when the carbonization effect tends to be complete. Especially in the biodegradation of organic compounds, such as nitrogen, organic matter and ammonia nitrogen, ammonia nitrogen is also one of the important indicators of pollution control. Therefore, the anaerobic aerobic A/O biological contact oxidation process is applied in wastewater treatment. The biochemical pool needs to be divided into two parts: pool pool and O pool.
