I. Project Overview
Txoj haujlwm no yog txoj haujlwm kho qaib cov dej khib nyiab ntawm Lingwu City Han-style Ecological Agriculture Development Co., Ltd. Lub tuam txhab nyob hauv Lingwu City, Ningxia, feem ntau koom nrog npua ua liaj ua teb, nrog 2,800 npua tam sim no nyob rau hauv Tshuag, thiab txhua hnub tso cov nqaij qaib pov tseg yog 600 m³. Cov dej khib nyiab yog los ntawm pighouse rinsing, fecal sib tov, thiab pab tu thaum ua liaj ua teb. Vim qhov tsis zoo ntawm cov chaw kho mob qub, cov dej khib nyiab tsis ua raws li cov qauv. Yog li ntawd, Jinan Guangbo Environmental Protection tau tso cai los muab cov phiaj xwm kho kom yooj yim kho kom haum, xav tau cov dej ntws los ua raws li "Pollutant Discharge Standards for Tsiaj thiab Poultry Industry" (GB 18596-2001), suav nrog kev ua haujlwm qis thiab kev siv peev txheej rau kev ua liaj ua teb, thiab kev tiv thaiv ib puag ncig.
II. Cov yam ntxwv ntawm cov dej khib nyiab thiab kev kho mob nyuaj
Cov ntsiab lus tseem ceeb ntawm lub tuam txhab cov dej khib nyiab: COD 3500-7000 mg / L, ammonia nitrogen 400-700 mg / L, SS 1800-3500 mg / L. Nws muaj ntau tus npua quav seem thiab cov khoom khib nyiab, nrog COD siab, siab ammonia nitrogen, ntau cov khib nyiab tshem tawm, yooj yim kom muaj ntxhiab tsw, thiab cov dej tsis zoo. Qhov kev sib tw tseem ceeb yog tias cov impurities yog cov khoom siv clogging thiab muaj kev tiv thaiv siab rau kev poob siab. Nws yog ib qho tsim nyog kom ua tiav cov qauv tso tawm sai sai hauv qhov chaw ntawm tus nqi qis.
III. Txoj Kev Kho Mob Core
Jinan Guangbo Environmental Protection tau kho cov txheej txheem yooj yim: Nqaij qaib cov dej khib nyiab → mechanical grille → solid-kua separator → regulating tank → UASB anaerobic reactor → aerobic biochemical pool → disinfection and discharge. Kev cia siab rau nws tus kheej-tsim UASB reactor kom ua tau zoo degrade siab -concentration organic teeb meem, ua ke nrog cov khoom sib cais- kua sib cais los daws qhov teeb meem ntawm impurity clogging, cov txheej txheem yog modularized thiab yooj yim rau kev khiav lag luam thiab tswj, haum rau lub suab nrov ntawm npua teb.
IV. Qhov project Achievements
Tom qab qhov project tau muab tso rau hauv kev siv, cov dej ntws tau ruaj khov thiab ua tau raws li cov qauv. COD thiab ammonia nitrogen tshem tawm cov nqi siab tshaj 96%, thiab cov khoom tshem tawm raug tshem tawm mus txog 98%. Nws ua tiav qhov kev hloov pauv ntawm biogas residue thiab biogas kua rau hauv cov chiv rau thaj av ib puag ncig, txuag 800,000 yuan hauv kev pov tseg thiab cov nqi chiv txhua xyoo. Nws daws sai sai rau lub tuam txhab cov teeb meem ib puag ncig thiab paub txog kev sib koom tes ntawm kev ua liaj ua teb npua thiab kev tiv thaiv ib puag ncig ecological.
