一． 設備簡介

1、 Equipment introduction

日化品廠產(chǎn)生的廢水量一般都不會很大，但是這些廢水中的污染濃度非常高，就算日化品的生產(chǎn)量再大，它的廢水因為日化品生產(chǎn)工序的原因?qū)е聫U水的產(chǎn)生量也不會太大，不過其水量和水質(zhì)的起伏也比較大不規(guī)律，不止如此廢水中的LAS和COD的濃度也比一般的水質(zhì)高出很多，其水中的活性劑在水中的存貨量非常的少因此另一方面也會造成破壞水質(zhì)的張力。如果遇到生物處理時活性劑又不得超過1000mg/L，因為生物處理工藝在遇到有毒物質(zhì)在好氧的階段會產(chǎn)生大量的泡沫；而中水回用他是一體化全自動的生物膜反應器，也叫MBR設備它的生物處理技術可完全代替了傳統(tǒng)的中水處理工藝，其可從進水到達標出水一體達成，可大|大的減少用地面積和人工，而且出水穩(wěn)定易操作可的去除水中的各種有毒物質(zhì)和，產(chǎn)出污泥量非常少，而水中的懸浮物質(zhì)幾乎接近零排出，還含有消毒殺菌的作用，直接處理到中水達標的標準。

The amount of waste water produced by daily chemical products factories is generally not very large, but the pollution concentration of these waste water is very high. No matter how large the production volume of daily chemical products is, the amount of waste water produced due to the production process of daily chemical products will not be too large, but the fluctuation of water quantity and quality is relatively large and irregular, More than that, the concentration of LAS and COD in wastewater is much higher than the general water quality, and the inventory of active agent in water is very small, so on the other hand, it will cause the tension of damaging water quality. In case of biological treatment, the active agent should not exceed 1000mg/L, because the biological treatment process will produce a large amount of foam when it meets toxic substances in the aerobic stage. The reclaimed water reuse is an integrated automatic biofilm reactor, also known as MBR equipment. Its biological treatment technology can completely replace the traditional reclaimed water treatment process. It can be achieved from the inlet water to the standard outlet water. It can greatly reduce the land area and manpower, and the effluent is stable and easy to operate. It can remove all kinds of toxic substances and pollutants in the water, and produce very little sludge, The suspended matter in the water is almost zero discharge, and it also has the function of disinfection and sterilization, which can be directly treated to the standard of reclaimed water.

宏潔水務的中水回用設備工藝已采用膜處理技術，包括預處理、超濾系統(tǒng)和反滲透(RO)系統(tǒng)及EDI系統(tǒng)（可選）幾部分。由于廢水通過現(xiàn)代技術的深度處理能夠達到生產(chǎn)用水標準或者生活雜用水標準，使廢水能夠循環(huán)使用，這樣企業(yè)對于廢水這一塊的整體運行費用得到大|大的降低，對環(huán)境保護起到很大的作用。

Membrane treatment technology has been adopted in the process of reclaimed water reuse equipment of Hongjie water, including pretreatment, ultrafiltration system, reverse osmosis (RO) system and EDI system (optional). Due to the advanced treatment of wastewater by modern technology, it can meet the production water standard or domestic miscellaneous water standard, so that the wastewater can be recycled, so that the overall operation cost of the enterprise for wastewater has been greatly reduced, which plays a great role in environmental protection.

9. Membrane treatment technology is the same as other filtration and separation technology. In the long-term operation process, the membrane is blocked as a kind of filter medium, and the water flow of membrane decreases gradually with the operation time. Effective backwashing and chemical cleaning can slow down the decline of membrane flux and maintain the effective service life of MBR system.
