我公司主要產(chǎn)品：水處理設(shè)備，污水處理設(shè)備、廢水處理設(shè)備、工業(yè)污水設(shè)備、農(nóng)業(yè)廢水設(shè)備、雨水凈水設(shè)備、醫(yī)院污水設(shè)備、鋼廠廢水設(shè)備、屠宰場(chǎng)廢水設(shè)備、食品廠廢水處理設(shè)備等多種設(shè)備，可根據(jù)要求專業(yè)定制水處理設(shè)備。

在生活污水、食品加工和造紙等工業(yè)廢水中，含有碳水化合物、蛋白質(zhì)、油脂、木質(zhì)素等有機(jī)物質(zhì)。這些物質(zhì)以懸浮或溶解狀態(tài)存在于污水中，可通過(guò)微生物的生物化學(xué)作用而分解。在其分解過(guò)程中需要消耗氧氣，因而被稱為耗氧污染物。這種污染物可造成水中溶解氧減少，影響魚類和其他水生生物的生長(zhǎng)。水中溶解氧耗盡后，有機(jī)物進(jìn)行厭氧分解，產(chǎn)生硫化氫、氨和硫醇等難聞氣味，使水質(zhì)進(jìn)一步惡化。水體中有機(jī)物成分非常復(fù)雜，耗氧有機(jī)物濃度常用單位體積水中耗氧物質(zhì)生化分解過(guò)程中所消耗的氧量表示，即以生化需氧量(BOD)表示。一般用20℃時(shí)，五天生化需氧量(BOD5)表示

市政污水處理工程案例(缺氧+傳統(tǒng)活性污泥法)

某污水處理廠是福建某市修建的一座大型污水處理廠。該廠的建設(shè)引進(jìn)關(guān)鍵技術(shù)、監(jiān)控裝置和設(shè)備，提高污水處理效率，充分利用生物能，節(jié)約能耗，節(jié)省用地，降低工程造價(jià)和運(yùn)行成本。

該污水處理廠的工藝設(shè)計(jì)，在進(jìn)行各種工藝方案比較的基礎(chǔ)上，仍選用鼓風(fēng)曝氣的設(shè)計(jì)方案。其理由是大型污水處理廠采用鼓風(fēng)曝氣工藝管理簡(jiǎn)便、運(yùn)行可靠。該污水處理廠肖化吸收了國(guó)外的先進(jìn)技術(shù)，對(duì)每個(gè)單項(xiàng)構(gòu)筑物及污水、污泥處理的細(xì)部方案都作了改進(jìn)，如進(jìn)水泵房及污水量計(jì)量的自動(dòng)控制、洗砂排砂、排泥濃度控制、溶解氧白控、脫氨反硝化工藝、二沉池出水槽新工藝、消化池投泥方式、大型消化池的沼氣攪拌、沼氣發(fā)電升壓聯(lián)網(wǎng)、沼氣鍋爐及排泥閥、可調(diào)堰、細(xì)格柵等先進(jìn)技術(shù)都在該廠得到了應(yīng)用。

 主要處理構(gòu)筑物及設(shè)備參數(shù)：

    1.進(jìn)水格柵

    格柵是污水處理廠的第一道預(yù)處理設(shè)施。該廠設(shè)6臺(tái)垂直格柵，由計(jì)算機(jī)程序控制。高水位時(shí)格柵清污機(jī)將連續(xù)工作，運(yùn)送格柵攔截的浮渣的皮帶運(yùn)輸機(jī)與格柵清污機(jī)聯(lián)鎖運(yùn)行，在所有格柵停止工作后，皮帶運(yùn)輸機(jī)仍將繼續(xù)運(yùn)行一段時(shí)間。

    6臺(tái)垂直格柵每臺(tái)寬2m，柵條凈距25 mm。

It always insists on making high-quality products, in line with the 10 purposes of "pursuit, employees, technology, spirit and interests". We have a group of competent managers and a high-quality professional and technical team, comfortable and elegant office environment and a new and modern standard factory. We are based on the quality of life, time as a credit, price competitive business belief, based on the Jining region

Our main products: water treatment equipment, sewage treatment equipment, sewage treatment equipment, industrial equipment, agricultural sewage water equipment, water purification equipment, water equipment, steel hospital sewage water equipment, slaughterhouse wastewater equipment, food factory wastewater treatment equipment and other equipment, can be customized according to the requirements of professional water treatment equipment.

It contains organic substances such as carbohydrates, proteins, Oils and lignin in sewage, food processing and papermaking industrial wastewater. These substances exist in the sewage in the state of suspension or dissolving, which can be decomposed by the biological chemical action of microbes. Oxygen consumption is needed in the process of decomposition, so it is called oxygen consumption. This kind of pollutant can cause the decrease of dissolved oxygen in water, which affects the growth of fish and other aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter is decomposed anaerobic, and the unpleasant odors such as hydrogen sulfide, ammonia and mercaptan are produced, and the water quality is further deteriorated. The composition of organic matter in water is very complex. The concentration of oxygen consumption organic matter is commonly expressed in the biochemical decomposition process of oxygen consumption substances in unit volume water, that is, biochemical oxygen demand (BOD). The five day biochemical oxygen demand (BOD5) is generally used at 20 degrees centigrade.

A case of municipal sewage treatment (anoxia + traditional activated sludge process)

A sewage treatment plant is a large sewage treatment plant built in Leshan. The key technologies, monitoring devices and equipment are introduced to improve the efficiency of sewage treatment, make full use of bio energy, save energy, save land and reduce project cost and operation cost.

On the basis of the comparison of various technological schemes, the design scheme of air blast aeration is still used in the process design of the sewage treatment plant.  The reason is that the large sewage treatment plant uses blast aeration technology to be easy to manage and operate reliably. The sewage treatment plant Xiao of absorbing foreign advanced technology, sewage and sludge treatment structures and the detail scheme of each individual were improved, such as the pump room and sewage metering automatic control, sand washing, sand mud concentration control, dissolved oxygen control, white ammonia denitrification process two, sedimentation tank tank process, digestion tank, large investment mud digester biogas stirring, biogas power generation, biogas boiler and boost network mud valve, adjustable weir, fine grid and other advanced technologies are applied in the factory.

Mainly dealing with the parameters of the structure and equipment:

1. inlet grille

The grille is the first pretreatment facility for the sewage treatment plant. The plant has 6 vertical grille, which is controlled by computer program. When the water level is high, the grille cleaning machine will interlock and run continuously with the grille intercepting scum belt conveyor and the grille cleaning machine. After all grille stops, the belt conveyor will continue to run for a period of time.

6 vertical grille is 2m with a width of 25 mm.

2. water inlet pump room

There are 6 HLWB-10 vertical vortex shell mixed flow pumps, 5 for 1.

Pump parameters: flow 1.32 cubic per second, head 13.2m, motor dynamic 260kw.

The pump room has 6 control water levels to control the operation of 5 pumps. In order to avoid the heavy load of individual pumps, the pump will circulate and run in turn.  When a pump stops working because of a failure, the other pump will be put into operation automatically.

3. surface grille

8 curved grille are located at the end of the sand sink. The width of each grid is 1.2m, the radius of curvature of the gate is 2 m, and the net distance of the gate bar is 10m.

The cleaning action of each grid is controlled by the computer according to the analog signal of the water level. When the water level difference is in the normal value, the cleaning work will act according to the setting time; when the current water level difference exceeds the set value, the cleaning work will be carried out continuously. If the cleaning work is too long for a long time, the computer will send out the alarm signal.

The scum scraped from the surface grille falls on the belt conveyor. The operation of the belt conveyor is interlocked with the grille cleaning machine. After the cleaning operation is stopped, the transporter will still run for a period of time.

4. sand sedimentation tank

The aeration and sand sedimentation tank has 6 corridors with a length of 30m, wide 4m and deep 4.3m, and the hydraulic retention time is about 6min.

The tank has a vibratory air (VIBRAIR) aerator with 648 gas supply of 5184 cubic meters per hour. There are two sand suction working bridges in the whole pool. There are 3 air lifting devices on each working bridge, which is responsible for the sand suction of the 3 corridors. The polluted sand is raised to the sand washing tank. After mixing, the organic matter is returned to the pump room with the flow of sand washing. The sand water is sent to the sanding machine for further dehydration. The sand separator is located on the top floor of the upper building of the inlet pump room, so that the dehydrated sand is flowing into the sand bucket.

The sand suction working bridge is controlled by a stroke switch, and a slag scraping facility is provided to remove the slag in the pool. The air lifting device requires continuous work and is controlled by a computer. When the air compressor fails, the standby machine can be automatically put into operation. The operating state of air compressor, sanding machine and pump is monitored by computer. If failure occurs, it will alarm automatically.

5. primary sink

Two schemes of rectangle and circle have been designed in the primary settling tank, which are compared from operation management, land occupation and concrete dosage. It is considered that the equipment of circular radial sedimentation tank is transported.
